When I run (in Windows 10):

_monailabel start\_server --app monaibundle --studies Task09\_Spleen/imagesTr --conf models renalStructures\_UNEST\_segmentation_

I get:

I don’t know what to do next. I installed monailabel and then monai-weekly to avoid the hardcoded site request issue with running the server in Windows.

Did you install MonaiLabel as [described here](https://projectweek.na-mic.org/PW37_2022_Virtual/Projects/MONAILabelLung/MONAILabel_Installation.html) and which works for most use cases?

What did you do differently?

Thank you for your assistance!

I was following directions from another web site, so I started over and used your directions. It got me this far:

_requests.exceptions.HTTPError: 404 Client Error: Not Found for url: [https://api.github.com/repos/Project-MONAI\model-zoo/releases](https://api.github.com/repos/Project-MONAI%5Cmodel-zoo/releases)_

The "" is the problem. I believe I read about this Windows specific error and that the solution was to install monailabel-weekly. I don’t know if this is what I should do and I don’t want to mess up what has gotten me this far. Do you have a suggestion?

Thanks again.

Gene

At which installation stage/command from the script (link above) does this happen?

I can reproduce that.  
Have you tried the radiology apps? Do you rely on monaibundle?

</div>

This is where I confess my ignorance… I want to use Slicer3d with a radiology app and was excited when I saw the kidney study because I have kidney cancer and want to learn as much as I can. Is there another way to run this study?

Is there a way to download the models and then refer to them on my PC vs getting them from github ?

Give it some time. You should get it going.  
I would recommend studying kidney (and related organs/tissues) anatomy.  
Also checkout this:

I figured it out. There are environment variables (MONI\_ZOO\_SOURCE = ‘’ and MONI\_ZOO\_REPO = ) that seems to be working.

Could you write a short passage that I could add to the installation script? Thank you.

How’s this?

**IF**

the git api request for a model fails due to an improperly formatted URL

(for example _[https://api.github.com/repos/Project-MONAI\model-zoo/releases](https://api.github.com/repos/Project-MONAI%5Cmodel-zoo/releases)_)

**THEN**

Step 1: The model “.zip” file can be downloaded (via web browser, for example) with a properly formatted version of the URL (replace '' with ‘/’) and then expanded into a folder on your PC.

Step 2: Set values for two environment variable the server will use as an override:

- $Env:MONAI\_ZOO\_SOURCE = ‘local’
- $Env:MONAI\_ZOO\_REPO = \< folder name \>

Step 3: Start monailabel server

Thanks for the ping @rbumm  
I’d suggest asking questions or reporting any issues on using MONAI Bundle or models from the model Zoo directly on the main GitHub repo ([GitHub - Project-MONAI/model-zoo: MONAI Model Zoo that hosts models in the MONAI Bundle format.](https://github.com/project-monai/model-zoo)). The developers will answer you within hours 🙂
