[QUESTION] Does COMET work on windows? about comet HOT 12 CLOSED

Actually I got the installation working - used python 3.7 + torch==1.4.0. Now I'm trying to run it end to end.

from comet.

Python 3.6 and python 3.8 also gave me similar errors.

from comet.

Hey @ranjita-naik! did you installed the latest COMET version ? pip install unbabel-comet==0.1.0?

COMET was not running for windows due to FastBPE package but I removed that dependency on the latest version. I see you are having a problem with test-tube, but I dont think test-tube is a COMET dependency

from comet.

pip install unbabel-comet==0.1.0

is also failing with the same error.

from comet.

Ok ok, I'll have to create a VM and try to see why it's breaking for windows.
I'll send you some updates early next week

from comet.

That's good news! is it running well?

from comet.

No, it failed with the following error

Ok that's a known error from fairseq: fairseq issue #865

I'll allocate some time next week to look at it. Probably you have to install fairseq locally and change the logic behind path splitting convention

from comet.

fairseq==0.10.0 doesn't have this problem but COMET depends on 0.9.0. After I fixed the path splitting logic in the locally installed version of fairseq==0.9.0, COMET ran fine. I also managed to create an exe through pyinstaller.

@ranjita-naik what did you do to get it working? I'm also having problems getting it installed on windows.

from comet.

@lodeous the following worked for me.

conda create --name comet_windows_3_7 python=3.7
conda activate comet_windows_3_7
pip install torch==1.4.0 -f https://download.pytorch.org/whl/torch_stable.html
pip install unbabel-comet==0.1.0 torch==1.4.0

I was able to build from the source as well; had to add torch==1.4.0 to poetry.

poetry add https://download.pytorch.org/whl/cu92/torch-1.4.0%2Bcu92-cp37-cp37m-win_amd64.whl

If the above doesn't work, do share the errors, I can take a look.

@ranjita-naik Thanks for helping out 🙏
