TIPSv2 Training code Release

[MlLearnerAkash]

Thanks for amazing work public. We are looking forward for release of training the model on a different dataset.

We won't be able to release the original training code, but we tried to show examples on how to take our models and train a model based on them.

See for example the foreground segmentation colab: https://colab.sandbox.google.com/github/google-deepmind/tips/blob/main/pytorch/TIPS_foreground_segmentation_demo.ipynb You should be able to follow similar instructions to fine-tune the model as needed.
