Error when doing backward computation using adacof.py.

[gaopinghai]

Thank you very much for your adacof.py algorithm. When I use it in my work, the forward computing is fine, however, when calling loss.backward(), I met the following errors:

  File "/home/gph/Desktop/rpg_e2vid_internal-master/e2vid_pytorch/trainer/lstm_trainer.py", line 265, in _train_epoch

You can try to repro this exception using the following code snippet. If that doesn't trigger the error, please include your original repro script when reporting this issue.

Any suggestions? Thanks!

CUDNN_STATUS_EXECUTION_FAILED error usually occurs when the CUDA, PyTorch, or graphic card driver versions don't match.
Also, CUDA_ERROR_ILLEGAL_ADDRESS error usually occurs when the inputs for the cupy functions are not appropriate (nan, inf, etc.)
Thanks.
