Hello, I have installed the extension OpenDose3D. On windows it has all the features, however, on ubuntu there were missing features. I was able to solve the problem by updating the scipy library thorugh the Python interactor by typing pip\_install(‘scipy -U’).

Just to let you know that there is this problem.

Thank you and kind regards.

Thanks for the report! I’m assuming you are using Slicer stable 4.11.20210226? A fix was issued in early March 2021 so you shouldn’t have this issue when using the latest Slicer preview build.

It shouldn’t be a problem if you use latest Slicer Preview as that commit came a few days after the latest Stable release back in February.

Yes I am using Slicer stable 4.11.20210226.  
The problem only existed on linux and not on windows.  
Many of my colleagues had this issue today as we tried using it, so it wasn’t only on my computer.
