After searching a lot inside the code the issue is not related with pin_memory on the dataloader but with the private method __generate_indices__ of the distributed sampler.
It is a problem even if the dataset contains 500K images.

Even in the case of 200K images, I get the error:

My config is the same as here: #21

Hi @ysig,
Thanks for your issue. Could you please set the data.repeat as a small number like 10? The variable repeats the indices of the whole dataset multiple times, requiring large memory.

Thank you, I will try it.
But what about the lod error: #22 (comment) ?
Thanks

The lod variable is defined here. My guess is that you are using StyleGAN2 generator. Since StyleGAN2 does not require progressive training, lod will be of no use in the generator and hence not well-defined.
