Error Using nVIDIA AIAA - Prostate Model

Dear all,

Unfortunately I’m facing issue using nVIDIA AIAA module: prostate MRI segmentation.

Running the AI I get this error:

" Traceback (most recent call last):

NvidiaAIAAClientAPI.client_api.AIAAException: (3, ‘Status: 500; Response: b’{“error”:{“message”:[],“type”:“InferenceServerException”},“success”:false}\n’’) "

Please, do you have any clues?

Thank you very much!

The prostate model probably fails because it requires two input images (T2 and ADC) and most likely the AIAA client that NVidia developers created for Slicer does not support this yet.

Please submit a feature request to NVidia developers at Issues · NVIDIA/ai-assisted-annotation-client · GitHub and copy the link here.
