MONAI Label - Training from Scratch

chendong9416 · November 27, 2022, 2:49pm

Currently, i am training my own dataset as the video showed. I wonder, after i trained about 10-20 cases, how can i use the trained model? Does a simple click on auto-segmentation works (it does not work in low cases trained model-report error)?

Hi @chendong9416,

Yes, you should be able to get a prediction by clicking the auto-segmentation button.

(it does not work in low cases trained model-report error)?

I’m not sure I understand this. Have you trained the model?

Hi, Andres,

There is problem in my training.

After manual segmentation of 5 cases with infra-renal abdominal aortic aneurysm and submit label in the monai label module in 3D slicer, i click on the “Train” button, but no accuracy was seen, below is the code in Anaconda Prompt

(base) C:\Users\xgzxe>conda activate monailabel

(monailabel) C:\Users\xgzxe>monailabel start_server --app radiology --studies my_dataset --conf models segmentation

Please tell me how can i solve this problem, thanks.

Hi @chendong9416,

Which Python version are you using? Can you please make sure you’re using 3.7/3.8/3.9 python versions?

It seems there are some issues with Python 3.10 support. Not everything is compatible with itk or some other libraries.

chendong9416 · November 30, 2022, 10:37pm

i am using python 3.9

diazandr3s · December 1, 2022, 3:20am

We’ve seen this issue before and it was solved by creating a python virtual env with Python 3.9 version. Please see here: RuntimeError: Unknown type: itkMatrixF44 · Issue #1064 · Project-MONAI/MONAILabel · GitHub

chendong9416 · December 3, 2022, 1:45am

Ok, i will try this way
