Reintroducing Batch Size Limitation to 1 in CoTracker3: Intentional Change or Bug?

[RoyMikeJiang]

I noticed that the latest CoTracker3 restricts the batch size to 1 (line 93 and 148 in train_on_kubric.py), whereas a previous version had removed this limitation (issue #36), allowing batch sizes greater than 1. Could you please clarify the reason for this change? Was it an intentional decision due to performance or compatibility issues, or is this a bug that needs to be addressed?

Looking forward to your feedback. Thank you!

Hi @RoyMikeJiang, we haven't tested CoTracker3 with batch sizes greater than 1. I'm not sure if it will work out of the box. This is something that needs to be addressed.
