hi, thanks for your great job. I noticed that this project is mainly based on VCL(which based on iCAN). And in VCL projects issues you once said that have met some bugs when running on multi-GPU. Does FCL have the same bug?
thank you!

No. in VCL, I tried to compose samples among GPUs, i.e., each GPU has an image (model parallel). But on FCL, It is not necessary to compose samples among different GPUs. But, I guess when we run FCL on multi-GPU, we need to tune the hyperparameters (e.g. lr)
