Azure-docs: Call the direct method section, BackEndApplication/azure-iothub-service-client failure.

[jflynn129]

I am trying to run the direct method example 'BackEndApplication.py'. I have followed the instructions but when I get to the part that it says to execute, the response is:

Traceback (most recent call last):
File "BackEndApplication.py", line 9, in <module>
import iothub_service_client
File "/home/xilinx/.local/lib/python2.7/site-packages/iothub_service_client/__init__.py", line 1, in <module>
from .iothub_service_client import *
ImportError: /home/xilinx/.local/lib/python2.7/site-packages/iothub_service_client/iothub_service_client.so: invalid ELF header

I understand that for this sample, you have to install the Pip package for the V1 service client, azure-iothub-service-client, which I did and this appears to be generating the error. Is this a known issue? Is there a work-around or another sample that works correctly that can be used?

@jflynn129 FYI, the topic has now been updated for V2 service and device clients. Please check it out. At this time, we're still working on some of the other topics. In the meantime, please check out the Python SDK for more detail about functionality and samples.
