Shape mismatch error occurs in multiprocessing

[cmh1027]

If I use 2~ gpus on inference, following error occurs.

RuntimeError: shape '[4, -1, 2, 16, 72]' is invalid for input of size 105523

I tested on 2/3/4 gpus, and all give the same error.

"My solution is to change the 'batch_size' value on line 32 of 'configs/opensora/inference/16x512x512.py' to 1, and that resolves the error."
