I have this error - how could i sovle it?

Thank you

Hello Oleg Syvyniuk,

Thank you for reaching out.

I successfully converted a yolo-v4-tf model from Open Model Zoo by using the following MO command:

python mo_tf.py --input_model="C:\Program Files (x86)\Intel\openvino_2021.3.394\deployment_tools\open_model_zoo\tools\downloader\public\yolo-v4-tf\yolo-v4.pb" --output_dir="C:\Program Files (x86)\Intel\openvino_2021.3.394\deployment_tools\open_model_zoo\tools\downloader\public\yolo-v4-tf" --data_type=FP32 --model_name=yolo-v4-tf --input_shape=[1,608,608,3] --input=image_input --scale_values=image_input[255] --reverse_input_channels

Can you give it a try and see if it is able to convert the model or not.

For your information Python 3.9 is not officially validated by OpenVINO.
