Internal Error when using Model Optimizer with Tensorflow

I am attempting to convert a tensorflow graph to a valid intermediate representation for use with the inference engine. I get the following internal error

[ ERROR ]  -------------------------------------------------

Hi Patel, D,

As the error "Permission denied: 'C:\\Program Files (x86)\\IntelSWTools\\openvino\\deployment_tools\\model_optimizer\\.\\inference_graph.bin'" suggests, it looks like there is an issue with writing permissions on the directory you are converting the model.

Since you are using Windows, I could suggest two things:

  • Open a Command Prompt and run as Administrator so it can write to such directory
  • Change to a directory that doesn't need Admin rights to write to it, for example C:\Users\your-username\Downloads

Please give it a try and let me know if the issue persists.

 

Regards,

Luis
