The code runs well in Linux, but with errors in windows.

Here is the code and error message: `t = tn.rand((3,3,3,3,3,3)) print(t)

t = tn.cross(function=lambda x: x**2, tensors=[t]) print(t)`

Traceback (most recent call last): File "C:\Users\4\PycharmProjects\TTALS\test.py", line 22, in t = tn.cross(function=lambda x: x ** 2, tensors=[t]) File "C:\Users\4\anaconda3\lib\site-packages\tntorch\cross.py", line 261, in cross ys_val = f([t[Xs_val].torch() for t in tensors]) File "C:\Users\4\anaconda3\lib\site-packages\tntorch\cross.py", line 261, in ys_val = f([t[Xs_val].torch() for t in tensors]) File "C:\Users\4\anaconda3\lib\site-packages\tntorch\tensor.py", line 1019, in getitem factors['index'] = get_key(counter, key[i]) File "C:\Users\4\anaconda3\lib\site-packages\tntorch\tensor.py", line 933, in get_key return self.cores[counter][..., key, :] IndexError: tensors used as indices must be long, byte or bool tensors

I change the "key" to 0, and the error is gone. So the problem may be the "key". The problem only occurs on Windows.
