Hello !  
I’m running the docker version of 3D-slicer : [GitHub - Slicer/SlicerDocker: Build, package, test, and run 3D Slicer and Slicer Extensions in Docker.](https://github.com/Slicer/SlicerDocker)

I have a problem when i’m trying to export the RT contour . I have also installed all the plugins.

"Failed to export using plugin DicomRtImportExportPluginClass  
Traceback (most recent call last):  
File “”, line 3, in   
File “/home/sliceruser/Slicer/NA-MIC/Extensions-30822/SlicerRT/lib/Slicer-5.0/qt-scripted-modules/DicomRtImportExportPlugin.py”, line 126, in export  
message = slicer.modules.dicomrtimportexport.logic().ExportDicomRTStudy(exportablesCollection)  
AttributeError: module ‘modules’ has no attribute ‘dicomrtimportexport’ "

How should I approach this ?  
Thanks,  
Alex

SlicerRT may not be properly installed. Do you get any errors on startup? Please see the log.

@cpinter  
I’m getting this error suddenly. I have done clean uninstall, installed again Slicer stable and Slicer nightly again the same issue mentioned by OP.

I see these errors in my Error log. Any idea what is happening? I have re-installed and installed again everything no success.

![CleanShot 2023-10-05 at 15.09.56](https://us1.discourse-cdn.com/flex002/uploads/slicer/original/3X/d/b/dbe1b63b800289c14486e7b1eea71c30c14f391a.png)

After a fresh install these errors are not there, but as soon as I install SlicerRT they appear

PS: I’m using Mac M2

This is one of the errors

Thanks for reporting - I have seen similar errors when trying to use the Extension manager on 5.4.0 on mac (intel mac pro) but haven’t had time to report or investigate.

I suspect there’s something getting corrupted in the installation paths because I had already installed some extensions and the errors started when I tried to install more.

Try running:

```auto
/Applications/Slicer.app/Contents/MacOS/Slicer --settings-path

```

And deleting the extensions folders from the indicated directory.

For me, the message from 5.4.0 is pasted below. I deleted the .app folder and re-installed a fresh download and still get the same message. It seems different from what @alireza is reporting.

```auto

Hi just checking in on this. I reverted back to a previous version, but I installed 5.5.0 today and I believe the issue hasn’t been fixed yet?

The issue has been fixed both in Slicer-5.4 and recent Slicer-5.5 releases. If you still experience any issues then let us know.
