Spleeter: [Feature] Provide SavedModels of pretrained models

[JeffreyCA]

Can you provide SavedModels of pretrained models (with the saved_model.pbfile)?

[bboettcher3]

Related to this, do you have any plans to convert the model to a TensorflowJS model? Having a Javascript counterpart would be pretty useful for embedding Spleeter in other applications.

Update: SavedModels are already currrently being outputted to /tmp/serving after running a spleeter separation.

You can change this output directory via the DEFAULT_EXPORT_DIRECTORY constant in estimator.py.

This will not happening from our side, the only migration we would consider at some point is porting library with TensorFlow 2. Plus I had checked a little bit before releasing and it would be very complicated as TensorFlow JS does not provide the range of functionality _Spleeter_ is currently using in _Python_ (estimator API to be more specific)

But if you are motivated feel free to explore, we would love having other language adoption from contributors.

I will close the issue since you seem to have figured out how but we will also upload those model on the release soon.

@JeffreyCA did you succeed in properly convert the SavedModes into tf.js?
I used the method explained here but had these warnings during conversion:

No I did not try to do that
