FP32 TO INT8 model conversion using Calibration tool

CJOY01 — Fri, 31 Jan 2020 21:13:40 GMT

I am facing one issue on using the calibrate.py tool used for calibrating the FP32 model.

I was successfully able to convert data annotation files using the below mentioned step.

python3 convert_annotation.py imagenet --annotation_file /home/cyril.pj/Downloads/downloadsforint8/val.txt --labels_file /home/cyril.pj/Downloads/downloadsforint8/synset_words.txt -ss 2000 -o ~/annotations -a imagenet_calibration.pickle -m imagenet_calibration.json

after successful completion of the above mentioned step, i was able to generate .json and .pickle file.

then for calibrating the model, i tried the below mentioned step,

python3 calibrate.py --config /opt/intel/openvino_2019.3.376/deployment_tools/tools/calibration_tool/configs/inception_v1.yml --definition /opt/intel/openvino_2019.3.376/deployment_tools/tools/calibration_tool/configs/definitions.yml -M /opt/intel/openvino_2019.3.376/deployment_tools/model_optimizer --tf_custom_op_config_dir ~/tf_custom_op_configs --models ~/models --source /home/cyril.pj/SSD_COPIED/rawfiles --annotations ~/annotations –cfc

but i am not able to successfully execute the calibration tool, the error i am getting is ,

Detected not satisfied dependencies:

networkx: installed: 2.4, required: 2.4

on checking the model_optimizer/requirements_tf.txt , the required version for networkx is given as networkx>=1.11,<2.4 .

I have tried with couple of networkx version between 1.11 and 2.3 and installed all its dependency packages, but the same issue is coming every time.

Kindly look into this issue,Any help you can give would be greatly appreciated.

Thanks and Regards,
