What the subject says.
I have a working Tensorflow installation via CUDA, CUDNN and pip. To examine a graph I followed a comment here which lead me to here, and accordingly I executed the command:
bazel build tensorflow/tools/graph_transforms:summarize_graph
Script kiddie that I am.
Ten minutes later I looked back at it and Bazel is furiously compiling C files with paths that look suspiciously like a source code checkout.
Is it actually compiling TF from source?!!!
Well yes, that is indeed what the bazel build command does.
If you look at the actual BUILD file (tensorflow/tools/graph_transform/BUILD) you'll see that it has its build rules and dependencies, which basically includes all the source code in that directory. The summarize_graph command's logic is included in those (you'll find that in summarize_graph_main.cc under the same directory).
You can follow the specific build rule to see what it does, or use a visualization tool. Here's what it looks like:
tf_cc_binary(
name = "summarize_graph",
copts = tf_copts(),
linkstatic = 1,
visibility = ["//visibility:public"],
deps = [
":summarize_graph_main_lib",
],
)
