Question: Native Python Support for Edge X Device Services

[nnshah1]

I really appreciated the time and thought you put into the tutorial and was pleasantly surprised that you added python scripts to create devices as well as send sensor data to EdgeX. Are there any plans to provide this as an SDK for EdgeX similar to the C and Go device service sdks?

Maybe a separate question, we have been working on a video analytics microservice based on OpenVINO and DLStreamer, and one of our samples uses the MQTT Device Service to send in detection results to Edge X.

https://github.com/intel/video-analytics-serving/tree/master/samples/edgex_bridge

If you have any feedback on the approach - would be interested. I've also thought that removing the MQTT bridge and using a native device service would be another approach - but had stopped short because of the lack of a supported python sdk. After coming across your tutorial - I'm rethinking that approach.

Thanks!

Hi Neelay, Thanks for your message. Great to hear the guide has been useful! *In regard to creating a separate Device service for your video analytics: * If the current implementation does the job and gives satisfactory performance I'd probably leave it as-is (if it's not broken - don't fix it). However, if you'd like to reduce the number of hoops your data has to pass through and possibly improve performance (as well as learn more about the innards of EdgeX) it'd certainly be an option to create your own. Please note that I haven't been involved with EdgeX for a long time now since Dell Tech reduced the focus on IoT. Cloud, on CC, may be able to offer better insights than I'm able. *In regard to a Python SDK;* To my knowledge there aren't any initiatives to provide a Python SDK. However, since I'm not directly involved with the development I don't have the latest information. I've CC'd Cloud Tsai at IOTech who likely knows a lot more about this. Hi Cloud, Would you happen to know if there's an SDK for Python in the works? I talked to Jim about it a couple of years back but haven't heard anything since then. All the best, Jonas

@jonas-werner thanks for the reference.
@nnshah1 the community wants to extend the Device SDK, absolutely including Python SDK, but we don't have enough resource and contributor to implement it. However, IOTech provide the commercial version of EdgeX Foundry with the OpenVino Device Service. It is implemented by C and might fit your needs.

We are working with Intel closely. Please let me know if you are interested in the commercial offering.

@jonas-werner @cloudxxx8 Thanks for the information! We met with Jim last fall, I'll reach out to see where things are headed in regards to an OpenVINO / DL Streamer device service.

It would be nice to see a python SDK also.
