I cannot install MONAI Label extension in 3DSlicer application on MacOS Monterey on a M1 Pro MacBook Pro (2021).
MonaiLabel is only available from the ExtensionsManager when using latest Slicer Preview. It is not available when using Slicer stable 4.11.20210226.
Did you try to install using latest Slicer preview and it fail to install? Or did you not find it in the ExtensionsManager because you were using Slicer 4.11.20210226?
Yes I installed the stable version therefore not found in ExtensionManager. I will install Slicer Preview and see what happens
