I'm trying solutions in #14 to downgrade pytorch to 2.1.0.

I'm trying solutions in #14 to downgrade pytorch to 2.1.0.

but in setup.py, the pytorch version must be >=2.3.1.
ok it might be a error

did you succeed? how did you do that? Thank you.

Same issue. Tried to downgrade to 2.1.0 - did not help

It was solved for me after running: python setup.py build_ext --inplace

Me too. GPT-4 told me to run this command. It solved.

Yep, it worked.

this seems like a nicer solution than downgrading pytorch.

I still have the issue even after python setup.py build_ext --inplace
is there any other way?

python setup.py clean --all then python setup.py build_ext --inplace works for me

Worked for me too. For anyone using Colab ran the following

import os

# Change directory to your project folder
project_dir = 'your_path'
os.chdir(project_dir)

# Remove the build directory if it exists
!rm -rf build

# Build the extension
!python setup.py build_ext --inplace

This works! I found that the install file setup.py needs this command, or some packages are not installed correctly. Thanks a lot!
