Qlik Sense SSE Python error - ModuleNotFoundError: No module named 'ServerSideExtension_pb2'

marcus_malinow — Sat, 16 Nov 2024 09:11:33 GMT

Hi,

hoping someone can help me here, with what is probably a newbie issue.

I'm trying to get the HelloWorld Python example up and running - https://github.com/qlik-oss/server-side-extension/blob/master/examples/python/GetStarted.md

So far I have:

Installed Python 3.6.3 x64

Followed the instructions here to install Python prerequisites - https://github.com/qlik-oss/server-side-extension/blob/master/examples/python/prerequisites.md

Downloaded .py, .json, and .config files from server-side-extension/examples/python/HelloWorld at master · qlik-oss/server-side-extension · GitHub to a subfolder on my desktop

Added SSEPlugin=HelloWorld,localhost:50052 to my settings.ini

When I attempt to run python ExtensionService_helloworld.py from my desktop subfolder I get the following error:

>python ExtensionService_helloworld.py

Traceback (most recent call last):

File "ExtensionService_helloworld.py", line 16, in <module>

import ServerSideExtension_pb2 as SSE

ModuleNotFoundError: No module named 'ServerSideExtension_pb2'

Any ideas what I could have got wrong here?

Thanks,

Marcus

Ok, think I have figured it out.

In addition to the HelloWorld source code from here - https://github.com/qlik-oss/server-side-extension/tree/master/examples/python/HelloWorld

It looks like I need the ServerSideExtension_pb2.py file, which I managed to find here - https://github.com/tim-wright/PythonSSE/blob/master/Toy%20Example/ServerSideExtension_pb2.py

Hi Camila,

yes it works, no expression errors in the app I'm working with.

Are you using the Python examples here? If so, do you see any errors in the Python command window?

Hi Marccus, It appears to me "INFO - *** Running server in insecure mode on port: 50052 ***"

Hi Camila,

that's not an issue - I see exactly the same in my environment. This is because there is no certificate installed.

I'm assuming you're using Qlik Sense Desktop here. Have you added the necessary information to the settings.ini file?

[Settings 7]

SSEPlugin=HelloWorld,localhost:50052

Yes, I have it added to the settings.ini file. Should I just run the "python ExtensionService_helloworld.py" command and then open QlikSense?

Hi Camila,

yes, that should be sufficient. Make sure the python script is running prior to opening Qlik Sense and it *should* work correctly

Strangely, now I work, thanks for the help. Have you worked with any prediction algorithm with python?

Hi Camila,

thus far my tinkerings have been solely around the examples, so no not yet with Python. I'm a little further ahead with the R component.

Hi Marcus,

Could you please help me here as i am getting an error while using an example (helloworld)

I am attaching the error in my reply.

I have checked about this error it is related to non compatibility with the google cloud.

Please suggest me if you have any idea of resolving it.

Might be GRPC not installed properly, or the library path where GRPC is installed is not added to sys.path()

Thanks

Hello Marcus,

I am trying to integrate python with Qlik Sense and started with the course video in official Qlik Sense website. I am using Qlik Sense Business where I was able to download Desktop version. I was able to run the ExtensionService_HelloWorld.py file and got the message Running Server in insecure mode. But my execution paused there and not able to see the GetCapabilities messages. I launched my Desktop App and drag the QVF file but not able to see the python functionality over there. Please find the attached.
