I think you may need import torch
before a line like from pytorch3d import _C
, which touches pytorch3d's internals, can possibly work.
from pytorch3d.
@nikhilaravi @bottler , Thanks a lot for your help. It's solved after installing the new updated repo. I confirmed that import torch
is needed before from pytorch3d import _C
as mentioned by @bottler .
from pytorch3d.
Thanks @jcjohnson @nikhilaravi for your replies.
@jcjohnson ,
import pytorch3d
This line works. But the second line from pytorch3d import _C
prompts the above error.
@nikhilaravi ,
I install it from local clone as guided
from pytorch3d.
Does it work if you import pytorch3d before importing _C?
import pytorch3d
from pytorch3d import _C
from pytorch3d.
Are you using the conda package or trying to install from source?
from pytorch3d.
@amiltonwong were you able to resolve this issue after installing from a local clone?
from pytorch3d.
hi @bottler @amiltonwong @jcjohnson @nikhilaravi @likethesky
I installed pytorch3D according to https://github.com/facebookresearch/pytorch3d/blob/master/INSTALL.md
And I still get an error:
File "/userhome/pytorch3d/pytorch3d/renderer/blending.py", line 8, in <module>
from pytorch3d import _C
ImportError: cannot import name '_C'
My system setting:
- python 3.6
- pytorch 1.16
- cuda 10.2
- Ubuntu 16
I have confirmed that
import pytorch
has been added in front of the
from pytorch3d import _C
Thank you in advance!
from pytorch3d.
@Frank-Dz Please open a new issue and paste the output of conda list
.
from pytorch3d.
@Frank-Dz I have the same error.Have you solved it?
from pytorch3d.
@bottler
My error is the same as Frank-Dz's which are as follows:
- File "/userhome/pytorch3d/pytorch3d/renderer/blending.py", line 8, in
- from pytorch3d import _C
- ImportError: cannot import name '_C'

@mengxiangxiang414 Please always open a new issue for things like this. How did you build/install PyTorch3D. It looks like you have installed from a local checkout of the repository, but did you actually build the library successfully? And did you build it with the current environment active? Were there and errors in building? Is there a file with a name beginning with _C
in /home/mxx/pytorch3d/pytorch3d
or /home/mxx/pytorch3d
? Best to open a new issue with a post explaining all this if it is still problematic.
NOTE for future passers-by: If you have an import error with PyTorch3D which you cannot solve, please open a new issue.
from pytorch3d.
@bottler
OK,thanks.
As you said,I have installed from a local clone of the source, but did not actually build the library successfully.
Two bad actions resulted in my error :
I ignored the
CUB library
i retryed installing it without the
rm -rf build/ **/*.so
It was my mistake.
from pytorch3d.
receiving the same error however when I import chamfer loss.
