Pytorch installation on raspberry pi fails

Hi all,

I have the follwoing problem. I would like to install pytorch on my raspberry pi. My installed Python version is 3.9.2 which should be compatible with Pytorch. I use the following command to install Pytorch:

pip3 install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cpu

Unfortunately I get the following error:

ERROR: Could not find a version that satisfies the requirement torch
ERROR: No matching distribution found for torch

I grasped the internet, however did not find a solution to my problem. It seems also that my Python Version should be supported. Any ideas what might went wrong?
