• TorchText version: '0.11.0a0+05cb992'

• Install pytext from source

cd /tmp 
git clone https://github.com/facebookresearch/pytext.git
cd pytext
sudo python3 setup.py install

• Import pytext

import pytext

ModuleNotFoundError: No module named 'pytorch'

Expected Results

• What did you expect to happen?
  No errors while importing pytext

Module causing this error pytorch.text.fb.utils is not mentioned in the requirements.txt. Is this an internal module to FB?
Any recommendation to circumvent this error?

Thanks!

@hudeven I came across a commit in June 2021 where you committed changes adding this import statement: 7ec49a8

from pytorch.text.fb.utils import PATH_MANAGER as PathManager  # noqa

Could you help with this issue?

Is torchtext's installation from source supported for non-facebook (external) users? It will be great to update the README.md if that is no longer the case.

Thanks!

same issue here.
Torch version: 1.5.1
TorchText version: 0.6.0
Install pytext from source

[lyan62]

same issue here. Torch version: 1.5.1 TorchText version: 0.6.0 Install pytext from source

same here, did you figure it out?

[bbored]

I guess our gpu is not supported from cuda or you don't have the right cuda version installed for torch.

Same problem here.

apparently this is a bug left in the source. installing from pypi does not have this problem.
