Support python 3.10

[skaldesh]

I followed the install guide on https://pypi.org/project/openvino-dev/
When running the command python -m pip install openvino-dev[caffe,onnx,tensorflow2,pytorch,mxnet]==2021.4.2 this error occurred:

I am using a virtual environment, as suggested in the install guide. Does somebody know why this fails?

@skaldesh which python version do you use?

[skaldesh]

python 3.10.1

[eaidova]

@skaldesh unfortunatly, this version is not supported on our side yet.. some thirdparty components can not be found for this python version on pypi (ctc-decode is available only for 3.9 now as I can see https://pypi.org/project/fast-ctc-decode/0.3.0/#files, you can try to install it manually from repo to resolve the current issue, but after that, you will get another issue because the key dependency of openvino-dev is openvino 2021.4.2, which is also available only for python3.9 and below)

My recommendation is downgrade python version for now... @slyubimt do you have plans to support python3.10 for openvino and openvino-dev for pypi distribution?

[skaldesh]

Ah understood, thank you! I'll change the title then...
