I am installing it like this: (venv) PS C:\Users_\OneDrive\Desktop\VOR-Models\2021-VOR-Model> pip install -r requirements.txt Because I am so lost, I will show you requirements.txt. This function literally installs everything before numpy, then it fails. clearbeautifulsoup4==4.9.3 certifi==2021.5.30 chardet==4.0.0 idna==2.10 numpy==1.20.3 pandas==1.2.4 python-dateutil==2.8.1 pytz==2021.1 requests==2.25.1 six==1.16.0 soupsieve==2.2.1 urllib3==1.26.5  Any help is appreciated. The reason I am doing this is because I took a course online (https://www.fantasyfootballdatapros.com/), and am trying to do data munging with pandas. I need NumPy for that. I also tried looking at other questions, but they didn't give me the answers I needed, or didn't have an answer at all. Please help.

Answer: It says it in the error message.  RuntimeWarning: NumPy 1.20.3 may not yet support Python 3.10.  Two quick trys:  Without looking through each packages, try removing numpy from requirements, and run "python -m pip install -r requirements.txt" again. Then in command line, try typing this to see if it installed because the other packages (ex. Tensorflow install numpy automatically, with the version it depends on).   python -m numpy   try a lower numpy version. inside requirments.txt try typing or something under 1.20.3   numpy==1.19.2
