过程问题
1 安装问题
anaconda prompt （anaconda3）base 环境下
WARNING: You are using pip version 21.1.1; however, version 22.0.4 is available.
升级pip
python -m pip install --upgrade pip
未成功
2 从头检查环境
cmd下
python
Python 3.8.5 (default, Sep 3 2020, 21:29:08) [MSC v.1916 64 bit (AMD64)] :: Anaconda, Inc. on win32
Warning:

not been activated. Libraries may fail to load. To activate this environment
please see https://conda.io/activation
C:\Users\>conda activate

conda安装，输入 conda --version
输入 conda info ，出现info内容则校验成功

3 CUDA
CUDA安装成功
C:\Users\>nvcc -V
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2020 NVIDIA Corporation
Built on Tue_Sep_15_19:12:04_Pacific_Daylight_Time_2020
Cuda compilation tools, release 11.1, V11.1.74
Build cuda_11.1.relgpu_drvr455TC455_06.29069683_0
4 测试pytorch
测试pytorch
import torch
x = torch.rand(2,3)
print(x)
应该输出的内容
tensor([[0.8159, 0.1670, 0.9336],
[0.9877, 0.6789, 0.2509]])
torch.cuda.is_available()
True
此时，GPU驱动和CUDA可支持pytorch的加速计算。
打开anaconda navigator，点击左边enviroment，然后creat d2l
5 安装 d2l 软件包
进入d2l-zh\pytorch 的cmd里
安装成功以后还需要安装 d2l 软件包，它封装了本书中常用的函数和类。
-U：将所有包升级到最新的可用版本
pip install -U d2l
D:\d2l\d2l-zh\pytorch>pip install -U d2l
6 开始使用d2l
打开anaconda prompt
conda activate d2l
退出输入
conda deactivate
7 遗留问题
paddlepaddle 2.1.0 环境与李沐d2l 环境产生冲突
ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
paddlepaddle 2.1.0 requires numpy<=1.19.3,>=1.13; python_version >= "3.5" and platform_system == "Windows", but you have numpy 1.22.2 which is incompatible.
mxnet 1.7.0.post2 requires numpy<1.17.0,>=1.8.2, but you have numpy 1.22.2 which is incompatible.
mxnet 1.7.0.post2 requires requests<2.19.0,>=2.18.4, but you have requests 2.25.1 which is incompatible.
WARNING: You are using pip version 21.1.1; however, version 22.0.4 is available.
You should consider upgrading via the 'D:\Anaconda3\python.exe -m pip install --upgrade pip' command.
Successfully installed d2l-0.17.4 matplotlib-3.4.0 numpy-1.22.2 pandas-1.2.4
pip 的依赖项解析器当前未考虑安装的所有包。此行为是以下依赖项冲突的根源。
paddlepaddle 2.1.0
mxnet 1.7.0
要求包低
incompatible 不匹配
于是：
就重新安装这几个包
pip install 包名 -i 地址
pip install 包名 -i https://pypi.tuna.tsinghua.edu.cn/simple # 清华

9 问题AttributeError: module ‘torch’ has no attribute ‘plot’
在linear-regression中
该步中
再次使用numpy进行可视化
x = np.arange(-7, 7, 0.01)
均值和标准差对
params = [(0, 1), (0, 2), (3, 1)]
d2l.plot(x, [normal(x, mu, sigma) for mu, sigma in params], xlabel='x',
ylabel='p(x)', figsize=(4.5, 2.5),
legend=[f'mean {mu}, std {sigma}' for mu, sigma in params])
产生如下错误
AttributeError Traceback (most recent call last)
<ipython-input-13-f717769c2c17> in <module>
4 # 均值和标准差对
5 params = [(0, 1), (0, 2), (3, 1)]
----> 6 d2l.plot(x, [normal(x, mu, sigma) for mu, sigma in params], xlabel='x',
7 ylabel='p(x)', figsize=(4.5, 2.5),
8 legend=[f'mean {mu}, std {sigma}' for mu, sigma in params])
AttributeError: module 'torch' has no attribute 'plot'
按上述步骤从头重新配置环境后解决问题。
注意jupyter notebook（anaconda3）中可以直接启动http://localhost:8888/
若需要jupyter打开的目录是D盘：
首先打开cmd输入命令 cd /d D:
cd /d D:
jupyter notebook
即可
