I want to use the python package 'numpy'. After a bit of research, I found that using apt install python3-numpy
seems to be the recommended way of installing it on the raspberry pi 3 (within a docker container based on 'arm32v7/python:latest').
The apt
installation command seems to work without any issues, but once I try to import numpy
in python, I get a ModuleNotFoundError: No mule named 'numpy'
.
How can I get numpy to work in python on my setup?
