AttributeError: module 'dill' has no attribute 'extend'

Question

I have just installed Pytorch, using:

(base) C:\>pip3 install torch torchvision torchaudio
Requirement already satisfied: torch in c:\users\Emil\appdata\roaming\python\python38\site-packages (1.9.0)
Requirement already satisfied: torchvision in c:\users\Emil\appdata\roaming\python\python38\site-packages (0.10.0)
Requirement already satisfied: torchaudio in c:\users\Emil\anaconda3\lib\site-packages (0.12.1)
Requirement already satisfied: typing-extensions in c:\users\Emil\anaconda3\lib\site-packages (from torch) (3.7.4.3)
Requirement already satisfied: numpy in c:\users\Emil\anaconda3\lib\site-packages (from torchvision) (1.22.2)
Requirement already satisfied: pillow>=5.3.0 in c:\users\Emil\anaconda3\lib\site-packages (from torchvision) (8.0.1)

Then, I tried to import torch in Spyder but received the following error:

import torch
C:\Users\Emil\AppData\Roaming\Python\Python38\site-packages\torch\package\_mock_zipreader.py:17: UserWarning: Failed to initialize NumPy: numpy.core.multiarray failed to import (Triggered internally at  ..\torch\csrc\utils\tensor_numpy.cpp:67.)

AttributeError: module 'dill' has no attribute 'extend'

What can I do to overcome this error?

I'm the `dill` author. The `dill` module does provide an `extend` attribute. I noticed that `dill` doesn't show up in the requirements, however... so, it might be possible that you have a really really really old version of `dill` installed. I would think more likely that there's an import error somewhere that overwrites the `dill` module. It may be worthwhile to report as a potential `pytorch` bug on GitHub if you haven't already. — Mike McKerns, Aug 22 '22 at 11:26

Based on Mike McKerns' comment, I successfully used:

pip install dill --upgrade
