Error optimizing tensorflow2 model

New Contributor I


i have trained this model  with tensorflow2 , now i am trying to optimize it with file with below command 

 python --saved_model_dir E:\tensorflow_models\my_mobilenetv2\saved_model\ --tensorflow_object_detection_api_pipeline_config E:\tensorflow_models\my_mobilenetv2\pipeline.config --tensorflow_use_custom_operations_config ssd_v2_support.json --data_type FP32 --reverse_input_channels

but i got below error:

Original exception message: 'ascii' codec can't decode byte 0x93 in position 183: ordinal not in range(128)



with --tensorflow_use_custom_operations_config ssd_v2_support.json i also tried  ssd_support_api_v1.15.

previously i have trained a ssd inception v2 module with tensorflow1.15 and optimization with that worked.

so is tensorflow 2 is supported with openvino


Thanks & Regards

Openvino does support TF2. You can refer here for more details:

the error 'ascii' codec can't decode byte 0x93 in position 183: ordinal not in range(128) indicates some type of Unicode Decode error. Perhaps you can try these workaround:
