如何学习TensorFlow源码

如果从源码构建TensorFlow会需要执行如下命令：
bazel build -c opt //tensorflow/tools/pip_package:build_pip_package
对应的BUILD文件的rule为：
sh_binary(
name = "build_pip_package",
srcs = ["build_pip_package.sh"],
data = [
"MANIFEST.in",
"README",
"setup.py",
"//tensorflow/core:framework_headers",
":other_headers",
":simple_console",
"//tensorflow:tensorflow_py",
"//tensorflow/examples/tutorials/mnist:package",
"//tensorflow/models/embedding:package",
"//tensorflow/models/image/cifar10:all_files",
"//tensorflow/models/image/mnist:convolutional",
"//tensorflow/models/rnn:package",
"//tensorflow/models/rnn/ptb:package",
"//tensorflow/models/rnn/translate:package",
"//tensorflow/tensorboard",
],
)
sh_binary在这里的主要作用是生成data的这些依赖。一个一个来看，一开始的三个文件MANIFEST.in、README、setup.py是直接存在的，因此不会有什么操作。
