Troubleshooting

numpy/scikit-image issues with M1 mac

If you are using an M1 mac and are having issues installing MapReader due to an error when installing numpy or scikit-image:

• Try separately installing the problem packages (edit as needed) and then installing MapReader:

  pip install numpy==1.21.5
  pip install scikit-image==0.18.3
  pip install mapreader
  

• Alternatively, you can try using a different version of openBLAS when installing:

  brew install openblas
  OPENBLAS="$(brew --prefix openblas)" pip install mapreader
