Thanks to the author for this excellent benchmark!
When I try to change the GPU devices setting, I get the following error:
RuntimeError: It looks like your LightningModule has parameters that were not used in producing the loss returned by training_step. If this is intentional, you must enable the detection of unused parameters in DDP, either by setting the string valuestrategy='ddp_find_unused_parameters_true'or by setting the flag in the strategy withstrategy=DDPStrategy(find_unused_parameters=True).
It might be some parameter just used for forward but not backward, which might result in this error.
Thank you for your feedback. We appreciate your interest in our benchmark. As of now, we haven't experimented with multi-GPU training. We will investigate this issue.
