Error ValueError: __len__() should return >= 0

I created my own sh file to run on my own dataset (4 features including the target) and I got this error
File "LTSF-Linear/exp/exp_main.py", line 42, in _get_data
data_set, data_loader = data_provider(self.args, flag) File "LTSF-Linear/data_provider/data_factory.py", line 46, in data_provider
print(flag, len(data_set))
ValueError: len() should return >= 0

Maybe you can make your dataset have the same format as the existing dataset.

Maybe you can make your code extensible to different formats!!! :)
