Cant setup Orthanc Mammography plugin on Windows 11

General

Greetings,
I have been pulling my hair out trying to setup the new Orthanc Mammography plugin on Windows 11. I’m using Python 3.12.

I execute the following commands to set up the Virtual enviroment

D:\orthanc-mammography-master>python -m venv mammovenv

D:\orthanc-mammography-master>cd mammovenv

D:\orthanc-mammography-master\mammovenv>cd scripts

D:\orthanc-mammography-master\mammovenv\Scripts>activate

(mammovenv) D:\orthanc-mammography-master\mammovenv\Scripts>D:\orthanc-mammography-master\mammovenv\Scripts\python.exe -m pip install --upgrade pip

(mammovenv) D:\orthanc-mammography-master\mammovenv\Scripts>cd ..

(mammovenv) D:\orthanc-mammography-master\mammovenv>cd ..

(mammovenv) D:\orthanc-mammography-master>pip install -r requirements.txt

Add the following to my config file

"Plugins" : [ "C:\\Orthanc\\Plugins" ],

"Python" : {
    "Path" : "D:\\orthanc-mammography-master\\mammography.py"
  },
  "Mammography" : {
    "VirtualEnv" : "D:\\orthanc-mammography-master\\mammovenv\\Lib\\site-packages"
  },

Then end up with the following error in the logs

Hello,

This kind of error is not linked to Orthanc, but to Python running PyTorch on Microsoft Windows. There are many threads regarding the same issue on Internet, for instance: Error loading "\lib\site-packages\torch\lib\shm.dll" or one of its dependencie - PyTorch Forums

I guess the first step would be to identify the missing DLL by using Dependency Walker on the D:\orthanc-mammography-master\mammovenv\Lib\site-packages\torch\lib\shm.dll shared library.

As I don’t use a proprietary operating system, I cannot provide any guidance. Maybe would it be time to try GNU/Linux?

There are some requirements due to which I have to use Windows :frowning:

So Im now seeing the “Stone Web Viewer (for mammography)”

but when I click that button I dont get any labeled masses

That’s because you haven’t applied the deep learning algorithm on the mammogram before opening the Stone Web viewer for mammography.

You first have to click on the yellow button “Deep learning for mammography” that appears at the instance level of the study containing the mammogram. This will call PyTorch to generate the DICOM-SR instance.

Check out the figure attached to my original post.

Dear Rana,

This is always the same answer: Check out your logs.

E0903 11:41:01.186138          HTTP-10 PluginsManager.cpp:154] Error in the REST callback, traceback:
<class 'RuntimeError'>
Could not infer dtype of numpy.float32

This indicates that you manually modified the requirements.txt file to change the version of some Python libraries, resulting in an environment that is incompatible with the RetinaNet model. Again, I cannot provide any support on Microsoft Windows.
