One question about the loss backward of temporal_deform_attn

[kimsimple]

Thanks open source for this good work.

But, I met a problem.

models/ops/temporal_deform_attn/functions/temporal_deform_attn_func.py", line 40, in backward value, value_spatial_shapes, value_level_start_index, sampling_locations, attention_weights, grad_output, ctx.seq2col_step) RuntimeError: Not implemented

I wonder if it is convenient for you to answer.

Thanks for your interest in this work. Currently, this repo only contains the model code. The full code is not ready for release.
