v0.9.91

Bug Fixes and Improvements

• Fixed CircleLoss bug, by improving the logsumexp keep_mask implementation. See #173
• Fixed convert_to_weights bug, which caused a runtime error when an empty indices_tuple was passed in. See #174
• ProxyAnchorLoss now adds miner weights to the exponents which are fed to logsumexp. This is equivalent to scaling each loss component by e^(miner_weight). The previous behavior was to scale each loss component by just miner_weight.

Other updates

• Added an example notebook which shows how to use a customized loss + miner in a simple training loop.
• A new arxiv paper and an improved Readme give a better high level explanation of the library.
• Added better explanations for the testers and the default accuracy metrics
