TensorFlow: Quantization Error "Analysis of target '//tensorflow/tools/graph_transforms:transform_graph' failed; build aborted."

Question

I am working to quantize my existing inception model graph in an attempt to reduce its size from ~89mb so something around 30mb as claimed according to the google tutorial here. The issue I am having is when I try to copy the following code snippet into mac OS terminal I get the following error.

Code Snippet I try to copy and run:

bazel build tensorflow/tools/graph_transforms:transform_graph
bazel-bin/tensorflow/tools/graph_transforms/transform_graph \
  --in_graph=/tmp/classify_image_graph_def.pb \
  --outputs="softmax" --out_graph=/tmp/quantized_graph.pb \
  --transforms='add_default_attributes strip_unused_nodes(type=float, shape="1,299,299,3")
    remove_nodes(op=Identity, op=CheckNumerics) fold_constants(ignore_errors=true)
    fold_batch_norms fold_old_batch_norms quantize_weights quantize_nodes
    strip_unused_nodes sort_by_execution_order'

A screenshot of the error I get:

The error essentially says the following in case you don't want to open the image:

ERROR: /Users/vivek/Desktop/commit2/tensorflow-master/tensorflow/core/BUILD:1546:1: no such target '//tensorflow/tools/git:gen/spec.json': target 'gen/spec.json' not declared in package 'tensorflow/tools/git' defined by /Users/vivek/Desktop/commit2/tensorflow-master/tensorflow/tools/git/BUILD and referenced by '//tensorflow/core:version_info_gen'.

    ERROR: Analysis of target '//tensorflow/tools/graph_transforms:transform_graph' failed; build aborted.
    INFO: Elapsed time: 28.452s

Any ideas as to why this is happening and how I can go about troubleshooting this?

Answer 1

It looks like you did not configure the tensorflow repo. You need to ./configure in the top level tensorflow directory and answer all the questions it asks before you can build anything in it (including transform_graph tool).

For more info, see section "Configure the installation" in https://www.tensorflow.org/install/install_sources
