MONAILabel server not responding and given this error: [25188] [MainThread] [ERROR] (uvicorn.error:59) - Application startup failed. Exiting.

[VSPuzzler]

Hello I am trying to start a server on my windows 10 laptop (doesn't have CUDA, but I assume it will still work just slower). I have followed the steps to use MONAILabel on 3DSlicer, but I am having issues starting the server. I run this command in command prompt: monailabel start_server --app radiology --studies Task02_Heart/imagesTr
I then get this error:

Does anyone know what is wrong?

[tangy5]

Hi, the command is not complete,

you will need to add a model name to start monailabel command: ex.g,
monailabel start_server --app radiology --studies Task02_Heart/imagesTr --conf models deepedit
But note here, we current don't have a pre-trained model for segmenting Task02 heart MRI data, you will need to provide your own pre-trained model.

Hello, where can I find the list of tasks that MONAILabel can do? I am trying to segment arteries from MRA data.

[diazandr3s]

Hi @VSPuzzler,

These are the currently available models in MONAI Label (https://github.com/Project-MONAI/MONAILabel/tree/main/sample-apps/radiology#pretrained-models) and in the MONAI Model Zoo (https://github.com/Project-MONAI/model-zoo/tree/dev/models)

I'm not sure there is a model for brain arteries segmentation using MRA. However, if you have labels, you may find this video useful to create your own model: https://youtu.be/3HTh2dqZqew

Hope this helps,

[VSPuzzler]

Hello, Thank you for the help. I will try that. I click train in 3d slicer on a test picture to make sure everything is working but this appears:

Hi @VSPuzzler,

It seems you don't have annotated samples to train the model. This is what I'm seeing from the logs:

ValueError: num_samples should be a positive integer value, but got num_samples=0

Did you organize the volumes as shown here or here? Are you using NIfTI or DICOM format?

If using DICOM format, you have to use a DICOM Web server. Otherwise, images have to be converted to NIfTI.

Hope this helps,
