mxProfileParser

A simple tool for parsing the profile.json file of mxnet

Enable mxnet profiler with environment variables

export MXNET_EXEC_BULK_EXEC_INFERENCE=0
export MXNET_EXEC_BULK_EXEC_TRAIN=0
export MXNET_PROFILER_AUTOSTART=1

Specify the json file. The tool will load profile.json by default

$ python mxProfileParser.py --file demo.json
