@rok I've investigated all tensor sparse formats and I want to give my final opinion: 1. Regarding [this](https://github.com/apache/arrow/issues/47520#issuecomment-3271622837), my assumption about case 2 was wrong; the problem only exists in the CooTensor format. 2. All types of sparse tensor format creation from dense tensors have the problem of handling negative zero. 3. HalfFloatType is not handled during the creation of any format at all (negative zero does not cause a memory problem). > This is quite unfortunate, and we should address it ASAP. pitrou, it would probably be best to fix this before the release. My initial solution is ready; however, since I've changed 12 files, it will take several days to clean it up. I think the release is frozen on October 6th. -- This is an automated message from the Apache Git Service.
