python-pip-conda中如何调用命令行帮助信息？command line help
竺焕
一、基本规律
1.1 对于python、pip、conda这种最顶层命令，可以直接调用-h获取下一层帮助信息。
1.2 有些父命令有子命令部分，这时候可能它的-h帮助信息不完全；比如pip的子命令有install，直接用pip -h无法取得关于install的比较详细的解释信息，而调用pip install -h才可获取与install子命令相关的帮助。
1.3 有些命令会把帮助信息划分版本，比如tensorboard的-h是简略版本，--helpful是详细版本。
二、对于规律一的演示
执行python -h，可以获得所有与python相关的命令，包括-h和--h这种调用帮助信息的命令。
(py38train) D:\BaiduNetdiskDownload\pycv-learning\pytorchlearning>python -h
usage: python [option] ... [-c cmd | -m mod | file | -] [arg] ...
Options and arguments (and corresponding environment variables):
-b : issue warnings about str(bytes_instance), str(bytearray_instance)
and comparing bytes/bytearray with str. (-bb: issue errors)
-B : don't write .pyc files on import; also PYTHONDONTWRITEBYTECODE=x
-c cmd : program passed in as string (terminates option list)
-d : debug output from parser; also PYTHONDEBUG=x
-E : ignore PYTHON* environment variables (such as PYTHONPATH)
-h : print this help message and exit (also --help)
-i : inspect interactively after running script; forces a prompt even
if stdin does not appear to be a terminal; also PYTHONINSPECT=x
-I : isolate Python from the user's environment (implies -E and -s)
-m mod : run library module as a script (terminates option list)
-O : remove assert and __debug__-dependent statements; add .opt-1 before
.pyc extension; also PYTHONOPTIMIZE=x
-OO : do -O changes and also discard docstrings; add .opt-2 before
.pyc extension
-q : don't print version and copyright messages on interactive startup
-s : don't add user site directory to sys.path; also PYTHONNOUSERSITE
-S : don't imply 'import site' on initialization
-u : force the stdout and stderr streams to be unbuffered;
this option has no effect on stdin; also PYTHONUNBUFFERED=x
-v : verbose (trace import statements); also PYTHONVERBOSE=x
can be supplied multiple times to increase verbosity
-V : print the Python version number and exit (also --version)
when given twice, print more information about the build
-W arg : warning control; arg is action:message:category:module:lineno
also PYTHONWARNINGS=arg
-x : skip first line of source, allowing use of non-Unix forms of #!cmd
-X opt : set implementation-specific option. The following options are available:
-X faulthandler: enable faulthandler
-X showrefcount: output the total reference count and number of used
memory blocks when the program finishes or after each statement in the
interactive interpreter. This only works on debug builds
-X tracemalloc: start tracing Python memory allocations using the
tracemalloc module. By default, only the most recent frame is stored in a
traceback of a trace. Use -X tracemalloc=NFRAME to start tracing with a
traceback limit of NFRAME frames
-X showalloccount: output the total count of allocated objects for each
type when the program finishes. This only works when Python was built with
COUNT_ALLOCS defined
-X importtime: show how long each import takes. It shows module name,
cumulative time (including nested imports) and self time (excluding
nested imports). Note that its output may be broken in multi-threaded
application. Typical usage is python3 -X importtime -c 'import asyncio'
-X dev: enable CPython's "development mode", introducing additional runtime
checks which are too expensive to be enabled by default. Effect of the
developer mode:
* Add default warning filter, as -W default
* Install debug hooks on memory allocators: see the PyMem_SetupDebugHooks() C function
* Enable the faulthandler module to dump the Python traceback on a crash
* Enable asyncio debug mode
* Set the dev_mode attribute of sys.flags to True
* io.IOBase destructor logs close() exceptions
-X utf8: enable UTF-8 mode for operating system interfaces, overriding the default
locale-aware mode. -X utf8=0 explicitly disables UTF-8 mode (even when it would
otherwise activate automatically)
-X pycache_prefix=PATH: enable writing .pyc files to a parallel tree rooted at the
given directory instead of to the code tree
--check-hash-based-pycs always|default|never:
control how Python invalidates hash-based .pyc files
file : program read from script file
- : program read from stdin (default; interactive mode if a tty)
arg ...: arguments passed to program in sys.argv[1:]
Other environment variables:
PYTHONSTARTUP: file executed on interactive startup (no default)
PYTHONPATH : ';'-separated list of directories prefixed to the
default module search path. The result is sys.path.
PYTHONHOME : alternate <prefix> directory (or <prefix>;<exec_prefix>).
The default module search path uses <prefix>\python{major}{minor}.
PYTHONCASEOK : ignore case in 'import' statements (Windows).
PYTHONUTF8: if set to 1, enable the UTF-8 mode.
PYTHONIOENCODING: Encoding[:errors] used for stdin/stdout/stderr.
PYTHONFAULTHANDLER: dump the Python traceback on fatal errors.
PYTHONHASHSEED: if this variable is set to 'random', a random value is used
to seed the hashes of str and bytes objects. It can also be set to an
integer in the range [0,4294967295] to get hash values with a
predictable seed.
PYTHONMALLOC: set the Python memory allocators and/or install debug hooks
on Python memory allocators. Use PYTHONMALLOC=debug to install debug
hooks.
PYTHONCOERCECLOCALE: if this variable is set to 0, it disables the locale
coercion behavior. Use PYTHONCOERCECLOCALE=warn to request display of
locale coercion and locale compatibility warnings on stderr.
PYTHONBREAKPOINT: if this variable is set to 0, it disables the default
debugger. It can be set to the callable of your debugger of choice.
PYTHONDEVMODE: enable the development mode.
PYTHONPYCACHEPREFIX: root directory for bytecode cache (pyc) files.
三、对于规律二的演示
而调用pip -h同理，可以看到下面的commands中有install，说明它是具备子命令的。

我们再打印pip install的帮助信息看看；果然关于install子命令的信息详细多了！
(py38train) D:\BaiduNetdiskDownload\pycv-learning\pytorchlearning>pip install -h
Usage:
pip install [options] <requirement specifier> [package-index-options] ...
pip install [options] -r <requirements file> [package-index-options] ...
pip install [options] [-e] <vcs project url> ...
pip install [options] [-e] <local project path> ...
pip install [options] <archive url/path> ...
Description:
Install packages from:
- PyPI (and other indexes) using requirement specifiers.
- VCS project urls.
- Local project directories.
- Local or remote source archives.
pip also supports installing from "requirements files", which provide
an easy way to specify a whole environment to be installed.
Install Options:
-r, --requirement <file> Install from the given requirements file. This option can be used multiple times.
-c, --constraint <file> Constrain versions using the given constraints file. This option can be used multiple times.
--no-deps Don't install package dependencies.
--pre Include pre-release and development versions. By default, pip only finds stable versions.
-e, --editable <path/url> Install a project in editable mode (i.e. setuptools "develop mode") from a local project path or a VCS url.
-t, --target <dir> Install packages into <dir>. By default this will not replace existing files/folders in <dir>. Use --upgrade to replace existing packages in <dir> with new
versions.
--platform <platform> Only use wheels compatible with <platform>. Defaults to the platform of the running system. Use this option multiple times to specify multiple platforms
supported by the target interpreter.
--python-version <python_version>
The Python interpreter version to use for wheel and "Requires-Python" compatibility checks. Defaults to a version derived from the running interpreter. The
version can be specified using up to three dot-separated integers (e.g. "3" for 3.0.0, "3.7" for 3.7.0, or "3.7.3"). A major-minor version can also be
given as a string without dots (e.g. "37" for 3.7.0).
--implementation <implementation>
Only use wheels compatible with Python implementation <implementation>, e.g. 'pp', 'jy', 'cp', or 'ip'. If not specified, then the current interpreter
implementation is used. Use 'py' to force implementation-agnostic wheels.
--abi <abi> Only use wheels compatible with Python abi <abi>, e.g. 'pypy_41'. If not specified, then the current interpreter abi tag is used. Use this option multiple
times to specify multiple abis supported by the target interpreter. Generally you will need to specify --implementation, --platform, and --python-version
when using this option.
--user Install to the Python user install directory for your platform. Typically ~/.local/, or %APPDATA%\Python on Windows. (See the Python documentation for
site.USER_BASE for full details.)
--root <dir> Install everything relative to this alternate root directory.
--prefix <dir> Installation prefix where lib, bin and other top-level folders are placed
--src <dir> Directory to check out editable projects into. The default in a virtualenv is "<venv path>/src". The default for global installs is "<current dir>/src".
-U, --upgrade Upgrade all specified packages to the newest available version. The handling of dependencies depends on the upgrade-strategy used.
--upgrade-strategy <upgrade_strategy>
Determines how dependency upgrading should be handled [default: only-if-needed]. "eager" - dependencies are upgraded regardless of whether the currently
installed version satisfies the requirements of the upgraded package(s). "only-if-needed" - are upgraded only when they do not satisfy the requirements of
the upgraded package(s).
--force-reinstall Reinstall all packages even if they are already up-to-date.
-I, --ignore-installed Ignore the installed packages, overwriting them. This can break your system if the existing package is of a different version or was installed with a
different package manager!
--ignore-requires-python Ignore the Requires-Python information.
--no-build-isolation Disable isolation when building a modern source distribution. Build dependencies specified by PEP 518 must be already installed if this option is used.
--use-pep517 Use PEP 517 for building source distributions (use --no-use-pep517 to force legacy behaviour).
--install-option <options> Extra arguments to be supplied to the setup.py install command (use like --install-option="--install-scripts=/usr/local/bin"). Use multiple --install-
option options to pass multiple options to setup.py install. If you are using an option with a directory path, be sure to use absolute path.
--global-option <options> Extra global options to be supplied to the setup.py call before the install or bdist_wheel command.
--compile Compile Python source files to bytecode
--no-compile Do not compile Python source files to bytecode
--no-warn-script-location Do not warn when installing scripts outside PATH
--no-warn-conflicts Do not warn about broken dependencies
--no-binary <format_control>
Do not use binary packages. Can be supplied multiple times, and each time adds to the existing value. Accepts either ":all:" to disable all binary
packages, ":none:" to empty the set (notice the colons), or one or more package names with commas between them (no colons). Note that some packages are
tricky to compile and may fail to install when this option is used on them.
--only-binary <format_control>
Do not use source packages. Can be supplied multiple times, and each time adds to the existing value. Accepts either ":all:" to disable all source
packages, ":none:" to empty the set, or one or more package names with commas between them. Packages without binary distributions will fail to install when
this option is used on them.
--prefer-binary Prefer older binary packages over newer source packages.
--require-hashes Require a hash to check each requirement against, for repeatable installs. This option is implied when any package in a requirements file has a --hash
option.
--progress-bar <progress_bar>
Specify type of progress to be displayed [off|on|ascii|pretty|emoji] (default: on)
--no-clean Don't clean up build directories.
Package Index Options:
-i, --index-url <url> Base URL of the Python Package Index (default https://pypi.tuna.tsinghua.edu.cn/simple). This should point to a repository compliant with PEP 503 (the
simple repository API) or a local directory laid out in the same format.
--extra-index-url <url> Extra URLs of package indexes to use in addition to --index-url. Should follow the same rules as --index-url.
--no-index Ignore package index (only looking at --find-links URLs instead).
-f, --find-links <url> If a URL or path to an html file, then parse for links to archives such as sdist (.tar.gz) or wheel (.whl) files. If a local path or file:// URL that's a
directory, then look for archives in the directory listing. Links to VCS project URLs are not supported.
General Options:
-h, --help Show help.
--isolated Run pip in an isolated mode, ignoring environment variables and user configuration.
-v, --verbose Give more output. Option is additive, and can be used up to 3 times.
-V, --version Show version and exit.
-q, --quiet Give less output. Option is additive, and can be used up to 3 times (corresponding to WARNING, ERROR, and CRITICAL logging levels).
--log <path> Path to a verbose appending log.
--no-input Disable prompting for input.
--proxy <proxy> Specify a proxy in the form [user:passwd@]proxy.server:port.
--retries <retries> Maximum number of retries each connection should attempt (default 5 times).
--timeout <sec> Set the socket timeout (default 15 seconds).
--exists-action <action> Default action when a path already exists: (s)witch, (i)gnore, (w)ipe, (b)ackup, (a)bort.
--trusted-host <hostname> Mark this host or host:port pair as trusted, even though it does not have valid or any HTTPS.
--cert <path> Path to PEM-encoded CA certificate bundle. If provided, overrides the default. See 'SSL Certificate Verification' in pip documentation for more
information.
--client-cert <path> Path to SSL client certificate, a single file containing the private key and the certificate in PEM format.
--cache-dir <dir> Store the cache data in <dir>.
--no-cache-dir Disable the cache.
--disable-pip-version-check
Don't periodically check PyPI to determine whether a new version of pip is available for download. Implied with --no-index.
--no-color Suppress colored output.
--no-python-version-warning
Silence deprecation warnings for upcoming unsupported Pythons.
--use-feature <feature> Enable new functionality, that may be backward incompatible.
--use-deprecated <feature> Enable deprecated functionality, that will be removed in the future.
除此之外，不是所有的父命令的子命令版本都会在父命令的-h打印信息中显示出来；比如conda父命令下有activate命令，然而没有显示在commands中。
(base) D:\BaiduNetdiskDownload\pycv-learning\pytorchlearning>conda -h
usage: conda-script.py [-h] [-V] command ...
conda is a tool for managing and deploying applications, environments and packages.
Options:
positional arguments:
command
clean Remove unused packages and caches.
compare Compare packages between conda environments.
config Modify configuration values in .condarc. This is modeled after the git config command. Writes to the user .condarc file (C:\Users\Administrator\.condarc) by default.
create Create a new conda environment from a list of specified packages.
help Displays a list of available conda commands and their help strings.
info Display information about current conda install.
init Initialize conda for shell interaction. [Experimental]
install Installs a list of packages into a specified conda environment.
list List linked packages in a conda environment.
package Low-level conda package utility. (EXPERIMENTAL)
remove Remove a list of packages from a specified conda environment.
uninstall Alias for conda remove.
run Run an executable in a conda environment. [Experimental]
search Search for packages and display associated information. The input is a MatchSpec, a query language for conda packages. See examples below.
update Updates conda packages to the latest compatible version.
upgrade Alias for conda update.
optional arguments:
-h, --help Show this help message and exit.
-V, --version Show the conda version number and exit.
conda commands available from other packages:
build
content-trust
convert
debug
develop
env
index
inspect
metapackage
pack
render
repo
server
skeleton
token
verify
但是，其实activate是存在的，该命令可以用来激活某一个虚拟环境；执行conda activate -h看看，明显没有pip install -h的帮助信息更详细，所以其实conda的开发者对这一部分完善得不是很好。
(base) D:\BaiduNetdiskDownload\pycv-learning\pytorchlearning>conda activate -h
usage: conda activate [-h] [--[no-]stack] [env_name_or_prefix]
Activate a conda environment.
Options:
positional arguments:
env_name_or_prefix The environment name or prefix to activate. If the
prefix is a relative path, it must start with './'
(or '.\' on Windows).
optional arguments:
-h, --help Show this help message and exit.
--stack Stack the environment being activated on top of the
previous active environment, rather replacing the
current active environment with a new one. Currently,
only the PATH environment variable is stacked. This
may be enabled implicitly by the 'auto_stack'
configuration variable.
--no-stack Do not stack the environment. Overrides 'auto_stack'
setting.
四、对于规律三的演示
前面我已经提过，我们可以通过-h命令来获取父命令的所有帮助信息，包括如何调用它本身的帮助信息的帮助信息（套娃...）。下面执行tensorboard -h后，显示了--helpful那一行，表示可以通过该命令调用更详细的帮助信息。
(py38train) D:\BaiduNetdiskDownload\pycv-learning\pytorchlearning>tensorboard -h
2022-03-23 11:25:53.352669: I tensorflow/stream_executor/platform/default/dso_loader.cc:49] Successfully opened dynamic library cudart64_110.dll
usage: tensorboard [-h] [--helpfull] [--logdir PATH] [--logdir_spec PATH_SPEC] [--host ADDR] [--bind_all] [--port PORT] [--reuse_port BOOL] [--load_fast {false,auto,true}]

[--samples_per_plugin SAMPLES_PER_PLUGIN] [--whatif-use-unsafe-custom-prediction YOUR_CUSTOM_PREDICT_FUNCTION.py] [--whatif-data-dir PATH]
{serve,dev} ...
TensorBoard is a suite of web applications for inspecting and understanding your TensorFlow runs and graphs. https://github.com/tensorflow/tensorboard
positional arguments:
{serve,dev} TensorBoard subcommand (defaults to 'serve')
serve start local TensorBoard server (default subcommand)
dev upload data to TensorBoard.dev
optional arguments:
-h, --help show this help message and exit
--helpfull show full help message and exit
--logdir PATH Directory where TensorBoard will look to find TensorFlow event files that it can display. TensorBoard will recursively walk the directory structure rooted at
logdir, looking for .*tfevents.* files. A leading tilde will be expanded with the semantics of Python's os.expanduser function.
--logdir_spec PATH_SPEC
Like `--logdir`, but with special interpretation for commas and colons: commas separate multiple runs, where a colon specifies a new name for a run. For example:
`tensorboard --logdir_spec=name1:/path/to/logs/1,name2:/path/to/logs/2`. This flag is discouraged and can usually be avoided. TensorBoard walks log directories
recursively; for finer-grained control, prefer using a symlink tree. Some features may not work when using `--logdir_spec` instead of `--logdir`.
--host ADDR What host to listen to (default: localhost). To serve to the entire local network on both IPv4 and IPv6, see `--bind_all`, with which this option is mutually
exclusive.
--bind_all Serve on all public interfaces. This will expose your TensorBoard instance to the network on both IPv4 and IPv6 (where available). Mutually exclusive with
`--host`.
--port PORT Port to serve TensorBoard on. Pass 0 to request an unused port selected by the operating system, or pass "default" to try to bind to the default port (6006) but
search for a nearby free port if the default port is unavailable. (default: "default").
--reuse_port BOOL Enables the SO_REUSEPORT option on the socket opened by TensorBoard's HTTP server, for platforms that support it. This is useful in cases when a parent process
has obtained the port already and wants to delegate access to the port to TensorBoard as a subprocess.(default: False).
--load_fast {false,auto,true}
Use alternate mechanism to load data. Typically 100x faster or more, but only available on some platforms and invocations. Defaults to "auto" to use this new
mode only if available, otherwise falling back to the legacy loading path. Set to "true" to suppress the advisory note and hard-fail if the fast codepath is not
available. Set to "false" to always fall back. Feedback/issues: https://github.com/tensorflow/tensorboard/issues/4784 (default: auto)
--extra_data_server_flags EXTRA_DATA_SERVER_FLAGS
Experimental. With `--load_fast`, pass these additional command-line flags to the data server. Subject to POSIX word splitting per `shlex.split`. Meant for
debugging; not officially supported.
--grpc_creds_type {local,ssl,ssl_dev}
Experimental. The type of credentials to use to connect to the data server. (default: local)
--grpc_data_provider PORT
Experimental. Address of a gRPC server exposing a data provider. Set to empty string to disable. (default: )
--purge_orphaned_data BOOL
Whether to purge data that may have been orphaned due to TensorBoard restarts. Setting --purge_orphaned_data=False can be used to debug data disappearance.
(default: True)
--db URI [experimental] sets SQL database URI and enables DB backend mode, which is read-only unless --db_import is also passed.
--db_import [experimental] enables DB read-and-import mode, which in combination with --logdir imports event files into a DB backend on the fly. The backing DB is temporary
unless --db is also passed to specify a DB path to use.
--inspect Prints digests of event files to command line. This is useful when no data is shown on TensorBoard, or the data shown looks weird. Must specify one of `logdir`
or `event_file` flag. Example usage: `tensorboard --inspect --logdir mylogdir --tag loss` See tensorboard/backend/event_processing/event_file_inspector.py for
more info.
--version_tb Prints the version of Tensorboard
--tag TAG tag to query for; used with --inspect
--event_file PATH The particular event file to query for. Only used if --inspect is present and --logdir is not specified.
--path_prefix PATH An optional, relative prefix to the path, e.g. "/path/to/tensorboard". resulting in the new base url being located at localhost:6006/path/to/tensorboard under
default settings. A leading slash is required when specifying the path_prefix. A trailing slash is optional and has no effect. The path_prefix can be leveraged
for path based routing of an ELB when the website base_url is not available e.g. "example.site.com/path/to/tensorboard/".
--window_title TEXT changes title of browser window
--max_reload_threads COUNT
The max number of threads that TensorBoard can use to reload runs. Not relevant for db read-only mode. Each thread reloads one run at a time. (default: 1)
--reload_interval SECONDS
How often the backend should load more data, in seconds. Set to 0 to load just once at startup. Must be non-negative. (default: 5.0)
--reload_task TYPE [experimental] The mechanism to use for the background data reload task. The default "auto" option will conditionally use threads for legacy reloading and a
child process for DB import reloading. The "process" option is only useful with DB import mode. The "blocking" option will block startup until reload finishes,
and requires --load_interval=0. (default: auto)
--reload_multifile BOOL
[experimental] If true, this enables experimental support for continuously polling multiple event files in each run directory for newly appended data (rather
than only polling the last event file). Event files will only be polled as long as their most recently read data is newer than the threshold defined by
--reload_multifile_inactive_secs, to limit resource usage. Beware of running out of memory if the logdir contains many active event files. (default: false)
--reload_multifile_inactive_secs SECONDS
[experimental] Configures the age threshold in seconds at which an event file that has no event wall time more recent than that will be considered an inactive
file and no longer polled (to limit resource usage). If set to -1, no maximum age will be enforced, but beware of running out of memory and heavier filesystem
read traffic. If set to 0, this reverts to the older last-file-only polling strategy (akin to --reload_multifile=false). (default: 86400 - intended to ensure an
event file remains active if it receives new data at least once per 24 hour period)
--generic_data TYPE [experimental] Hints whether plugins should read from generic data provider infrastructure. For plugins that support only the legacy multiplexer APIs or only the
generic data APIs, this option has no effect. The "auto" option enables this only for plugins that are considered to have stable support for generic data
providers. (default: auto)
--samples_per_plugin SAMPLES_PER_PLUGIN
An optional comma separated list of plugin_name=num_samples pairs to explicitly specify how many samples to keep per tag for that plugin. For unspecified
plugins, TensorBoard randomly downsamples logged summaries to reasonable values to prevent out-of-memory errors for long running jobs. This flag allows fine
control over that downsampling. Note that 0 means keep all samples of that type. For instance "scalars=500,images=0" keeps 500 scalars and all images. Most users
should not need to set this flag.
what-if-tool:
--whatif-use-unsafe-custom-prediction YOUR_CUSTOM_PREDICT_FUNCTION.py
The file location of your custom prediction function. Note that the flag executes arbitrary code, so make sure you passed the correct file location. See how to
define the function in https://github.com/PAIR-code/what-if-tool/blob/master/README.md
--whatif-data-dir PATH
An optional additional directory under which the What-If Tool can load example data from, outside of the TensorBoard logdir.
