[Minigo] Pre-trained checkpoint conversion script across frameworks

[nv-rborkar]

As per #317 , we would like all references that use pre-trained weights or start from a checkpoint to provide conversion scripts for use across different frameworks (Pytorch, TF, & other frameworks of choice for submission) to ensure submitters use the same pre-approved checkpoint.

@christ1ne could you assign to the reference owner?

[christ1ne]

@johntran-nv are you referring to the following example for converting the weights? mlcommons/training#436
That's a from PyTorch model. Is there an TF model weights export example?
Thanks!

@delock who's the reference owner.

[johntran-nv]

Yes that's what we're referring to. Sorry but I don't know of a similar TF export example. We could ask the Google folks for help, if you want.

[christ1ne]

I think we should ask the Google folks for an TF example.
Meanwhile, I am not sure if all the TF models can be converted to Pytorch as they are today.
