"Disabling PyTorch because PyTorch >= 2.1 is required but found 1.12.1+cu113" leads to errors in YOLOWorld instantiation

[paulo-cortesao]

Thank you for your research.

I am working on a Ubuntu 24.04 machine, which originally supports CUDA 12.8 and gcc-13. The python version in my environment is 3.10.9. For the purpose of installing this software, I installed CUDA 11.3, gcc-9 and g++-9, appropriately setting the CXX and CUDA_HOME variables before installation, and using the linux-5.4-headers in the setup of MinkowskiEngine.

I used a slightly different command for installing torch-scatter since the version given by the link was incorrect: pip3 install torch-scatter==2.1.0 -f https://data.pyg.org/whl/torch-1.12.1+cu113.html

I also explicitly installed numpy==1.26.4 to avoid errors in the installation of mmcv==2.0.0 and other packages.

After following the installation instructions up until Pointnet2, installing pytorch-lightning==1.7.2 makes pip remove the existing installation of torch==1.12.1 and replace it with torch==2.7.1. YOLO-World also explicitly requires torch>=2.1.0.

Finishing all the steps, I tried to run the single_scene_inference.py file without arguments but torch is explicitly deactivated in the beginning of the program:

Disabling PyTorch because PyTorch >= 2.1 is required but found 1.12.1+cu113
None of PyTorch, TensorFlow >= 2.0, or Flax have been found. Models won't be available and only tokenizers, configuration and file/data utilities can be used.

As such, instantiating the YOLOWorld class (more precisely, initializing network_2d) leads to this error:

CLIPTextModelWithProjection requires the PyTorch library but it was not found in your environment. 
Check out the instructions on the installation page: https://pytorch.org/get-started/locally/ and follow the ones that match your environment. 
Please note that you may need to restart your runtime after installation.

How can I correct this error? Do you use a different python version? Is there any detail of the setup that I might have missed?

I appreciate your time and attention.

I eventually found the solution to the problem. It had to do with the version of the transformers library. Pip installed transformers==4.53.0 by default but looking at the documentation in https://pypi.org/project/transformers/ the latest version supporting torch==1.12 is transformers==4.45.2. As such I would suggest changing the dependencies in models/YOLO-World/pyproject.toml or anywhere else you see fit.

Hey @paulo-cortesao ,

Thanks for sharing, will update the file.
