Issue while pip installing fft package

[ghost]

I have following issue while installing pytorch-fft package.

This looks like an issue with the ffi_extension package handling Windows style path names, are you able to run the examples here?

@fswerty @riceric22 i got the same issue when i pip install pytorch-fft on windows.

I made a ugly hack and successfully installed this plugin.

I also added an compiled egg, you may try your luck.

I had the same problem in windows 10 and so I tried the "hacked one". Got the following errors;

What's your cl.exe version? Does it match the version of your toolset? I analysed build flags, there are few differences:

1073741515 means some dll cannot be found. Maybe you should install some extra windows toolset.

Hi, i 'm also working on windows (10), i followd the steps bloodmage suggested but when i try to run python -c "import pytorch_fft" i get: Traceback (most recent call last): File "<string>", line 1, in <module> File "C:\Users\iariav\Anaconda3\envs\pytorch\lib\site-packages\pytorch_fft\__init__.py", line 1, in <module> from . import fft File "C:\Users\iariav\Anaconda3\envs\pytorch\lib\site-packages\pytorch_fft\fft\__init__.py", line 1, in <module> from .fft import * File "C:\Users\iariav\Anaconda3\envs\pytorch\lib\site-packages\pytorch_fft\fft\fft.py", line 3, in <module> from .._ext import th_fft File "C:\Users\iariav\Anaconda3\envs\pytorch\lib\site-packages\pytorch_fft\_ext\th_fft\__init__.py", line 3, in <module> from ._th_fft import lib as _lib, ffi as _ffi ImportError: DLL load failed: The specified module could not be found.

any idea what it could be? i made sure all compiled files are where they should (i have the _th_fft.pyd file at the th_fft folder)

thanks

Pytorch is updated, aten.lib and thc.lib should be regenerated using most recent dll. Check my most recent version or regenerate these libraries by yourself. That should work.
