I have a python application running on the latest Raspberry Pi OS (Debian version 11 (bullseye)) and I am getting an error when importing SciPy. The specific error is:
from scipy.linalg import _fblas
ImportError: libf77blas.so.3: cannot open shared object file: No such file or directory
Does anyone know why this error is being thrown or how to fix it? I have tried uninstalling and reinstalling SciPy but that doesn't help. I am also running in a python venv with python 3.9 and SciPy version 1.8.1 in case that makes a difference.
Fixed by installing libatlas3-base with apt-get install libatlas3-base which contains libf77blas.so.3.
