If on Windows, numpy has not yet released a precompiled wheel for Python 3.10. However you can try the unofficial wheels available at https://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy .

Specifically look for

`numpy‑1.21.2+mkl‑cp310‑cp310‑win_amd64.whl`

or`numpy‑1.21.2+mkl‑cp310‑cp310‑win32.whl`

depending on you system architecture.

After downloading the file go to the download directory and run `pip install "<filename>.whl"`

.)

(I have personally installed `numpy‑1.21.2+mkl‑cp310‑cp310‑win_amd64.whl`

and it worked for me.)
