Unable to run the prostate-mri-lesion-seg tutorial notebook using jupyter about research-contributions HOT 6 CLOSED

Notably, the error seems to be the same as in #342.

Thanks for giving the code a try @deepakri201!

The only thing that I can really give feedback based on the error you shared is to make sure that the notebook and the repository are in the right location...the notebook is originally designed to be executed right alongside the application folder, just as it is in the repository. I see that you changed the reference of the folder to an absolute path instead of the relative one...this shouldn't cause an error, but please verify location on your system is referenced properly. Otherwise try keeping as-is and executing alongside application code.

@fedorov I see the issue that you raised in #342 when trying to execute on Colab that is also similar. If you just run the notebook in Colab without cloning the full repository files, it will not be able to build the container.

Thanks for responding!

I was able to fix the above error (I had the wrong path name). Now I'm able to run the !monai-deploy package successfully, and also run the load_and_visualize_dicom_image.

However now I am running the following command !monai-deploy run lesion_seg_workflow_app:v1.0 {dcm_dir} output and get the following error about the organ model not being found:

I've downloaded the models from the Google drive folder, and placed them in prostate_mri_lesion_seg_app/models as the tutorial says. This is what my folder structure looks like:

I've also verified that the model.ts file does in fact exist in the organ folder.

Am I supposed to put the models in a different folder? Thanks!

Hey @deepakri201 ...that is strange. I am not sure what would be causing this error. I tried some different version of MONAI (I was originally testing with 1.2.0, but 1.3.0 is now available) but I couldn't reproduce. I am using monai==1.3.0 and monai-deploy-app-sdk==0.5.1. Are these the versions you are using?

A way to verify directly would be to try to look inside the docker container with a command like:
docker run --rm -it --entrypoint=/bin/bash lesion_seg_workflow_app:v1.0

This will open a shell in the container and you could look in the /opt/monai/app/models folder and see if the right model is there. If not, then that is the issue and the container is not properly copying in the models during the build. I see nothing wrong with your folder structure or naming, but maybe something else. Please give this a try and let me know.

Hi @jtetrea,

I checked my version numbers and I'm also using monai==1.3.0 and monai-deploy-app-sdk==0.5.1.

Interestingly, I re-ran everything (!monai-deploy package and !monai-deploy run), and now it seems to find the model just fine :) I was able to go through the notebook without any further issues.

Thank you for your help!
