This script was inspired by Han, Mao, and Dally's work and implements neural net quantization on TensorFlow graph files.
For a more in-depth explanation, see here.
python converge_weights.py FILE_PATH
Where FILE_PATH is the path to a GraphDef protobuf that encodes the graph you want to compress. This will output a FILE_PATH.min with is a valid GraphDef protobuf, and can be imported and used in the exact same way as FILE_PATH.
Additionally, the script accepts the following flags:
--whitelisted=SomeVariable,SomeOtherVariable: A comma separated list of constants not to cluster. Defaults to ''.--global_clusters: Turns on global clusters (one global codebook for weights rather than per layer weights).--n_clusters=256: How many clusters to form. Defaults to 256.--min_n_weights=256: In the case of global clusters, only clusters weights in layers with more than n weights (useful to filter out constants that aren't weights). Defaults to 256.
For further configuration options and implementation details, see the code in converge_weights.py.
