Installation Logs

Trying to install pandas with python3.9 -m pip install pandas
But it fails on installing Numpy. I have Numpy 1.22.4 installed. That version should be ok for installing pandas. However pandas tries to install cached numpy-1.26.1.tar.gz . I know that version is not possible to run on armv7l. How can i point pandas to numpy 1.22.4 when installing ??

Collecting numpy>=1.20.3 (from pandas==1.5.2)

Try explictly specifing numpy==1.22 in the install command.
