3d Slicer - MonaiLabel - custom labels

Support

Hi!

Windows 10, Slicer 3D 5.6.2, MonaiLabel 0.8.1.
I have a functioning Nvidia card with cuda support.
I ran the ‘hello world’ spleen segmentation.

I converted my dicom files to nifti, it works until I use custom labels in the monailabel config. If I use only 1 of my custom labels everything seems fine. After adding at least 1 more custom label, things are getting messy.
I’m unsure what I’m doing wrong.

Somewhere I read try to change the application (radiology) name. May it be the solution?

(I tried to use the --conf use_pretrained_model false, or changing it in the conf, the error is consistent)

Log:
Traceback (most recent call last):

The name change did not solve the problem. I’ve tried to manipulate the pip installs but had no success.

The error was on my side.
I found in another forum:
" remove all files in the model folder"

this solved the problem. It has to be done if the training is from absolute zero (“scratch”)
