RuntimeError: Expected to have finished reduction in the prior iteration before starting a new one.
Hi, I am facing the error message described below while training on my RTX 4090 GPU. I've adjusted the frame number to avoid exceeding the memory limitation, and left the remaining code unchanged. However, the training process could not function properly. Besides, I've seen someone posted similar issue previously, though I did not understand how did he solve his problem. Thus, I'm posting this issue again to ask for help. Thanks!
The following values were not passed to accelerate launch and had defaults used instead:
More than one GPU was found, enabling multi-GPU training.
If this was unintended please pass in --num_processes=1.
--num_machines was set to a value of 1
--mixed_precision was set to a value of 'no'
--dynamo_backend was set to a value of 'no'
To avoid this warning pass in values for each of the problematic parameters or run accelerate config.

making sure all forward function outputs participate in calculating loss.
If you already have done the above, then the distributed data parallel module wasn't able to locate the output tensors in the return value of your module's forward function. Please include the loss function and the structure of the return value of forward of your module when reporting this issue (e.g. list, dict, iterable).
