Reproduction

It saids I need tensorflow even I only use torch.

ValueError: Backend should be defined in the BACKENDS_MAPPING. Offending backend: tf

Expected behavior

@resc863 You need to more details than it just failed. Some sample reproducing script would be great plus stack trace.

Hi @resc863, I don't think we have version-specific wheels! Can you try installing from main and seeing if the problem goes away?
