Start pre-training

[Tang18970202]

What can I do about the problems I ran into running the train. py file?
File "C:\Users\admin\AppData\Local\Programs\Python\Python35\lib\site-packages\numpy\core\shape_base.py", line 283, in vstack
return _nx.concatenate(arrs, 0)
File "<array_function internals>", line 6, in concatenate
ValueError: need at least one array to concatenate

@Tang18970202 Can u provide more detail on this error (e.g., Python package versions, what have you done before running the script, etc.)?

It seems to be because the dataset has not been loaded, and when np.vstack is run on an empty array it throws this error.
this is part of the _load_npz_list_files method in the dataloader.py file
