ModuleNotFoundError with PyTorch and setting a custom interpreter

Description

What steps will reproduce the problem?

i install Spyder_64bit_full.exe 5.1.2, Because the built-in spyderIDE does not have a pytorch library, I use the pytorch that has been installed in Anaconda before, and then import exteral module ,spyder report internal problem,for example:

import torch
b = torch.arange(0,20)
k = b.numpy()
print(k)

i have already set python interpreter is D:/Anaconda3/python.exe ,anaconda have many modules before.

Traceback

Exception in comms call get_namespace_view:
  File "D:\Program Files\spyder\pkgs\spyder_kernels\comms\commbase.py", line 315, in _comm_message
    encoding='latin-1')

@ccordoba12 I was able to reproduce this. @cuixing158 as a workaround seems like checking the option Exclude unsupported data types in the variable explorer options menu prevents the error dialog poping-up. Let us know if that helps!

@dalthviz, could you try to solve this problem next week to see if we can include a fix for this in 5.2.0?
