I was not able to run the pip-compile commands to generate the new requirements files, it failed on protobuf version error

Adding grpcio-status<1.49.0 to the requirement.in can probably fix it.

@pingsutw, what do you think about having a model.py rather than a model folder, or better module.py since the type transformer will be for tf.Module? It seems to make more sense to me. Since we also have a PR for tensor, we can have a tensor.py file.

yes. make sense. I prefer module.py

@techytushar, let me know once the changes are in.

[techytushar]

@samhita-alla I have pushed the changes.

Note: I could not use the generic Struct type for storing the layer config because in protobuf format the int values gets converted to float due to which when we convert it back to the tf layer it was not able to parse it. So I have stored them as simple json string

@samhita-alla since its the last day of Hacktoberfest and all comments are resolved, please can you merge this PR or add label so that it can count towards my contribution

[samhita-alla]

@techytushar, I'll merge the PR later as I need to push some changes.

We're going to need to move these changes into the tensorflow plugin @eapolinario

Great, I'll make sure to incorporate those there.
