GPU显存占满，但利用率低 #30

batch_size设为4，pin_memory=true, num_workers=8, 现在GPU利用率一直在1%左右，你们有这样的情况吗？

@Dany119 I'm facing the same issue, have you solved it?

Facing the same issue, anyone solved it yet?

@adijindal30 it seems like the data is loaded into GPU but it's still waiting for the "post-processing" step to finish, I think it's a bottleneck.
