1.48 Programmer's Guide
The documents in this unit dive into the details of writing TensorFlow code. This section begins with the following guides, each of which explain a particular aspect of TensorFlow:
- @{$variables$Variables: Creation, Initialization, Saving, and Loading}, which details the mechanics of TensorFlow Variables.
- @{$dims_types$Tensor Ranks, Shapes, and Types}, which explains Tensor rank (the number of dimensions), shape (the size of each dimension), and datatypes.
- @{$variable_scope$Sharing Variables}, which explains how to share and manage large sets of variables when building complex models.
- @{$threading_and_queues$Threading and Queues}, which explains TensorFlow's rich queuing system.
- @{$reading_data$Reading Data}, which documents three different mechanisms for getting data into a TensorFlow program.
The following guide is helpful when training a complex model over multiple days:
- @{$supervisor$Supervisor: Training Helper for Days-Long Trainings}, which explains how to gracefully handle system crashes during a lengthy training session.
TensorFlow provides a debugger named tfdbg
, which is documented in the following two guides:
- @{$debugger$TensorFlow Debugger (tfdbg) Command-Line-Interface Tutorial: MNIST}, which walks you through the use of
tfdbg
within an application written in the low-level TensorFlow API. - @{$tfdbg-tflearn$How to Use TensorFlow Debugger (tfdbg) with tf.contrib.learn}, which demonstrates how to use
tfdbg
within the Estimators API.
A MetaGraph
consists of both a computational graph and its associated metadata. A MetaGraph
contains the information required to continue training, perform evaluation, or run inference on a previously trained graph. The following guide details MetaGraph
objects:
- @{$meta_graph$Exporting and Importing a MetaGraph}.
To learn about the TensorFlow versioning scheme, consult the following two guides:
- @{$version_semantics$TensorFlow Version Semantics}, which explains TensorFlow's versioning nomenclature and compatibility rules.
- @{$data_versions$TensorFlow Data Versioning: GraphDefs and Checkpoints}, which explains how TensorFlow adds versioning information to computational graphs and checkpoints in order to support compatibility across versions.
We conclude this section with a FAQ about TensorFlow programming:
- @{$faq$Frequently Asked Questions}
