Hi!
I builded 3DSlicer in my computer, and tried to install the SlicerRT extension on Extension Manager, but when I tried to open my DICOM images I had this issue:

Traceback (most recent call last):

Anyone had this issue too? Or anyone know how to fix it?
I builded 3D Slicer 4.11.0-2020-04-25 on Ubuntu 18.04.4 LTS

Thanks.

Extension manager downloads only work for factory built Slicer releases. If you build your own Slicer, you will need to build your own SlicerRT too.

Thanks, it worked for me! However, I had to build another extension, as it is not available in the extension manager, and I need SlicerRT to be able to use my images. Would you know how I could put the two extensions together in a Slicer?

If you ask this because you use SlicerRT with the SlicerWithSlicerRT executable, then you need to add the binary folders as additional module directories. You can find all the information in the documentation https://www.slicer.org/wiki/Documentation/Nightly/Developers/FAQ#How_to_manually_install_an_extension_package.3F
