inputs is empty

[tigerccx]

I am trying to run the model with BalancedDataParallel and I initialized my network with
tt = TT(args, device).to(device); if ((not args.cpu) and (args.num_gpu > 1)): tt = BalancedDataParallel(1 ,tt, dim=0);.

But I keep getting this error:
data_parallel_my.py", line 79, in scatter bsz = inputs[0].size(self.dim) IndexError: tuple index out of range

I printed inputs out and found it to be empty. My code works with DataParallel itself so I am not sure what went wrong. Here is where I try to call the network: srhd, S, T_lv3, T_lv2, T_lv1 = tt(lr=sr, ref=ref)

I can not find any error juse through your code here，maybe you can make some debug to find solution.
