Use Python 3.8.*. No point in 3.9, however it should be fine.
Run these to test if install is successful, and install some important packages. Please follow the errors as they come, one will ask the user to install C++ build tools, if not already installed (see below). This will take several minutes, as the dependencies are a few GBs. You must be off VPN, or set-proxy, as shown below.
