Beginner Windows and Python question

COLE_Jonathan_ROYAL · November 10, 2021, 4:18pm

Hi

Sorry if the answer is obvious, but I can’t seem to get anywhere.

I’m on Windows (because that’s what the hospital have available for me at the moment). I’ve installed Orthanc 64 bit, Python 64 bit and the pre-built Python plugin. Both Python and the plugin are version 3.7 (though I also tried 3.8). When I start Orthanc it sees the plugin and correctly loads my script from the directory given in the config. But then it never seems to run the script. I’ve tried various things, including nonsense that should throw an error, but even with verbose turned on I don’t see anything from my script. Just the usual python importers.

Are there any known issues on Windows? I’m trying to get a linux option sorted, or else get docker desktop but there are hurdles for those.

Kind regards

Jonathan

Hi Jonathan,

I think that would help if you could share your scripts (and logs) .

Also note that, under Windows, you won’t see the python print statements in the logs. You should use orthanc.LogInfo() or orthanc.LogWarning() instead.

HTH,

Hi

My current script is:

import orthanc

orthanc.LogInfo(“Hello world”)

I’ve tried various different things though and none seem to work.

Hi Jonathan,

You should try with orthanc.LogWarning() instead or increase the verbosity of your logs to “verbose”: https://book.orthanc-server.com/faq/log.html

Thanks. Unfortunately that’s not made any difference.

I don’t think the Python script is actually running. I think I’ve got compatible versions, but is there anything else I should be looking out for?

The plugin seems ok and tries to load your script:

W1116 09:31:21.589056 PluginsManager.cpp:168] Python plugin is initializing

W1116 09:31:21.589056 PluginsManager.cpp:168] Using Python script “orthanc.py” from directory: C:\Program Files\Orthanc Server

Maybe you should try to move the script to another folder ? FYI, here’s what I have on my side with your script:

“PythonScript”: “c:\Users\Alain\Downloads\orthanc.py”,

with this script content:

import orthanc
orthanc.LogWarning(“Hello world”)

and then, my logs:

W1117 08:29:31.827634 PluginsManager.cpp:269] Registering plugin ‘python’ (version 3.1)
