no such file problem when training ST 2urban scripts

[lyhnsn]

When training self-training 2urban scripts, such as CBST_train.py and IAST_train.py, there is a problem which is 'FileNotFoundError: No such file: '/home/xxx/ssuda/UDA/log/cbst/2urban/pseudo_label/3814.png''. I guess this is because that the batch size is set to 2, and as expected the problem is solved when batch size is modified to 1.

So, I wonder that if this is a bug or something what?

Thanks for your excellent works!
