module 'encoding._ext.encoding_lib' has no attribute 'Encoding_Float_sum_square_Forward' about pytorch-encoding HOT 6 CLOSED

Are you running the script in the repo base folder? Try to run it in different folder.

from pytorch-encoding.

No, this is not the issue here. I'm running my script from a separate folder, say /home/<user>/code. But thanks for having a look at this. I'll keep you updated when I found something that could be responsible for this issue.
Is it intentional that the folder /home/<user>/.conda/envs/pytorch-0.3.1-3.5-s/lib/python3.5/site-packages/encoding/_ext does not contain any .py files?

from pytorch-encoding.

something wrong with the installation, there should be __init__.py automatically generated:
_encoding_lib.abi3.so* __init__.py __pycache__/

from pytorch-encoding.

Ok, strange. It just didn't copy the __init__.py file for some reason. I also couldn't find anything in the log files, Everything seemed to be run though without errors. I tried installation multiple times.

I ended up just copying this file manually from the sources to this directory, this solved the issue.

But now I get:

  [...]

TypeError: initializer for ctype 'struct THCudaTensor *' must be a cdata pointer, not Variable

Is this related to my incomplete installation or actually a new bug?

P.S. cffi package version 1.11.5 is installed on my system.

Edit: Solved by changing two lines of code!
It was not related to this issue, it's rather a pytorch 0.3.1 compatibility issue, I opened a new issue report for this.

And finally, the code runs on my machine! Thanks so far for all the helpful comments!
