[Resolved] Pytorch v0.2 OSX issue

1

I just upgraded to v0.2 with pip install http://download.pytorch.org/whl/torch-0.2.0.post1-cp27-none-macosx_10_7_x86_64.whl and pip install torchvision. When I try importing torch in the shell, I get:

>>> import torch
RuntimeError: module compiled against API version 0xb but this version of numpy is 0xa
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/torch/__init__.py", line 53, in <module>
    from torch._C import *
ImportError: numpy.core.multiarray failed to import

I already have numpy and can do

>>> import numpy as np
>>> np.empty(3)
array([ 0.,  0.,  2.])
>>>

But cannot use Pytorch…

Had same issue. I uninstalled and reinstalled numpy than installed torch again. That fixed for me

3

pip install --upgrade numpy will solve it.

This does not solve it for me:

import numpy as np
np.__version__

'1.11.2'

import torch
