Summary
I have added a missing installation instruction necessary to install
monailabel
on Ubuntu.Issue
If you attempt to install
monailabel
through pip on Ubuntu, you needpython3-dev
. This is due to theopenslide-python
dependency that needs to be compiled during installation (see here for more information about this issue).If not, installation will fail resulting in the error log:
Logs
This error was observed on Ubuntu 20.04 with Python 3.8 attempting to install latest release of monailabel from PyPI.
Note that a PR to build precompiled binaries of
openslide-python
has been made, so this might not be an issue in the future, but the PR has yet to be merged or included in the latest release (see openslide/openslide-python#188)
