ERROR: Package 'lietorch' requires a different Python: 3.8.20 not in '>=3.9'

I encountered an issue when trying to install lietorch with Python 3.8 - the error message indicated that the package requires Python version 3.9 or higher (specifically: 'ERROR: Package 'lietorch' requires a different Python: 3.8.20 not in '>=3.9''). However, when I switched to Python 3.9 and attempted to run the data preprocess, another problem occurred:

Any suggestions?

I solved the problem. Still using the python 3.8. The instructions are as follows:

pip install torch==1.13.0+cu117 torchvision==0.14.0+cu117 torchaudio==0.13.0 --extra-index-url https://download.pytorch.org/whl/cu117
pip install -r requirements.txt
pip install open3d
pip install git+https://github.com/aimi-lab/lietorch.git
pip install tqdm

Be noted, when install lietorch, please use the forked repository by aimi-lab, instead of the original repo.
