WebThis may or may not be related and may already be a know issue but Dataloader seems to be broken with respect to cuda forking semantics. Forking after calling cuInit is not allowed by cuda which Dataloader (at least in 1.3.1) appears to do. This is probably fine since Dataloader doesn't actually make any cuda calls but I could envision a case where a … WebJan 5, 2024 · in = torch.cat ( (in, ...)) will slow down your code as you are concatenating to the same tensor in each iteration. Append to data to a list and create the tensor after all samples of the current batch were already appended to it. fried-chicken January 10, 2024, 7:58am #4. Thanks a lot.

Why is Dataloader faster than simply torch.cat() on Dataset?
