Hi @vsnlme108 ,
The pip install failure may be related to not being in the correct environment. You have to make sure you first activate the environment in which the OMERO server is installed before running the pip install command.
The “omero duplicate” functionality should indeed allow you to do what you want. If you import all the Images into Datasets in a Project inside one Group, then you can duplicate that Project and move the duplicate copy in its entirety to a second Group, and, if desired, duplicate again and move to the third Group, etc. Users belonging to each of the Groups will see the entire Project with all Datasets and Images inside and all annotations and modifications within each Group will be confined to just that one Group. But almost no additional hard disk space will be used (except for some space for additional records in the postgres DB).
