Problems installing and importing pytorch

Question

It's taken me hours trying to install pytorch using an anaconda environment. It appears that I've finally managed it using conda install filename.tar.bz2:

But when trying to import the package using import pytorch I get:

>>> import pytorch
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named 'pytorch'

And when I try import torch:

>>> import torch
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Users\conner\Anaconda3\envs\pytorch\lib\site-packages\torch\__init__.py", line 76, in <module>
    from torch._C import *
ImportError: DLL load failed: The specified module could not be found.

The difference in errors is actually encouraging, but I don't know how to interpret it. Why am I not able to import pytorch if it shows up on the list of packages in the environment?

EDIT

After continued attempts, I'll ask a much more general question: Has anyone had success at installing and importing Pytorch for Windows 10 on a 64-bit machine?

Answer 1

When I installed pytorch by creating a conda environment, it worked fine.

Below are the steps that I tried out. Please try it from your side.

1. conda create -n (env_name) python=3.5
2. source activate (env_name)
3. conda install pytorch-cpu -c pytorch
4. pip install torchvision

Answer 2

What finally ended up working was to reinstall the entire Anaconda package, although this seems less than ideal.
