Whenever I import numpy in any program I get this error:

Original error was: dlopen(/Users/ulto4/miniforge3/envs/python386/lib/python3.8/site-packages/numpy/core/_multiarray_umath.cpython-38-darwin.so, 2): Library not loaded: @rpath/libcblas.3.dylib
  Referenced from: /Users/ulto4/miniforge3/envs/python386/lib/python3.8/site-packages/numpy/core/_multiarray_umath.cpython-38-darwin.so
  Reason: image not found

This happens with numpy 1.19.5 and numpy 1.21.1 on my Mac M1. The weird thing is just a month ago everything was fine. I install numpy with conda install numpy.

Again the code doesn't matter because even if I just have import numpy I get this error.

How would I go about fixing this?

Try to install openblas with conda:

conda install -c conda-forge openblas

in your terminal.

You should see something like this:
