The problem shows as follows:
“Traceback (most recent call last):
File “train.py”, line 26, in 
train_net(config)
File “train.py”, line 17, in train_net
solver = Solver(config, data_loader=data_loader, device=“cuda”)
File “/home/zhangwei/PSGAN-master/psgan/solver.py”, line 41, in init
self.snapshot_step = config.LOG.SNAPSHOT_STEP // torch.cuda.device_count()”
Can someone tell me what   this problem is?
