guess
guess that you didn't push c++ extensions onto github

Hi, I also encountered this mistake. Can you tell me how to solve it?
thanks!

still stuck in it

Hi,I also encountered this problem.
Please ensure that you have source activate to your conda env before running python setup.py build develop.

I surely did what you said. But I still haven't work out it

[yghcats]

@huangr76 My conda is OK.

[kingbackyang]

@huangr76 My conda is OK
I have solved this problem by this website https://www.archlinux.org/packages/community/x86_64/python-pytorch/files/, which contains the complete source code of pytorch 1.0. The code in github is incomplete. I downloaded the packages and substituted the csrc (the compile error filefolder) filefolder for torch filefolder ( in the packages that downloaded). Done

Hi,

This problem usually happens because you are not using a nightly version of PyTorch 1.0, but an older version like PyTorch 0.4

Can you print the output of

import torch
print(torch.__version__)

and paste it here?

[kingbackyang]

You are right. But .....

[fmassa]

Try uninstalling PyTorch and installing it again. It should fix your issue I think

[yghcats]

@kingbackyang Can you tell me about your installation steps?
The downloaded folder contains: bin、lib、share
thanks！

recommend that you should check you installed pytorch version first. And according to the official step of the install.md, there is no problem at all. My bug is about my root environment path and virtual environment path.
Good luck!

Hi everyone, I'm facing a similar issue where this command conda install pytorch-nightly -c pytorch returns:
PackagesNotFoundError: The following packages are not available from current channels: pytorch-nightly

When I go with conda install pytorch -c pytorch it will automatically install pytorch 0.4. If I continue with the remaining steps it will fail in python setup.py build develop with a similar error as reported above.

Am right in thinking that this is mainly because I'm on Windows 10? It seems like the conda pytoruch-nightly 1.0 is still not supported for Windows.

CUDA 9, latest gcc for Windows.

pay attention to the official website of pytorch

[soumith]

Yes, PyTorch-nightly is not available for Windows yet.

[qalid7]

thanks both, may I ask from -based on previous releases- how long would it take for the Windows release? I can meanwhile entertain myself on a MBP but my main dev is still on Windows.
