deployed Custom Python IOT EDGE module on edge device always in "Stopped" status.

Question

Hi community,

I am currently working on creating python module for IOT EDGE device. When I only run "SimulatedTemperatureSensor" module provided by azure I am able to run it and monitor the data.

When try to run custom python module for IOT EDGE device, it is directly going to "Stopped" state in device.

My custom python code currently contains a simple dataframe operation. I am using vscode in local system for development. I am able to push the docker image as module to azure-container-registry. From there I am able deploy the module to IOT EDGE device.

I am following below links

• https://learn.microsoft.com/en-us/azure/iot-edge/tutorial-develop-for-linux?view=iotedge-1.4
• https://learn.microsoft.com/en-us/azure/iot-edge/tutorial-python-module?view=iotedge-1.4

Answer 1

Hello @Roshan Ardeshana , Please make sure your module is running , it has to meet the condition in your code. Please take a closer look at the below code where i am running the sample in a While loop.

Similarly please have a look at the sample Github page :

When i don't use the While loop or the criteria is not met , my Python module is Stopped and no further telemetry is sent:

After i started using the criteria (While Loop) or any other condition as mentioned in the GitHub samples, the module keeps running.

Hello @Roshan Ardeshana ,
Did you try to check the logs on the IoT Edge for the Python's Custom module?

sudo iotedge logs dataframeModuleName

Hi @QuantumCache

I did check the logs. Unfortunately, I could not find any hints that can help. Here is the output of Troubleshoot your IoT Edge device.

Hi @QuantumCache

Thank you for your response.

I was able to resolve the issue related to 'Stopped" status.

Now module is in running state still I am not able to receive the responses from the python script. Python script contains a simple dataframe operations.
