ActiveGate remote plugin Python dependency - module not found

DynaMight Champion

I found various posts on python module dependencies, most of them related to OneAgent plugins and direct dependencies. I'm trying to build a AG remote plugin where the python module that the plugin depends on (ExasolDatabaseConnector) has another dependency to the pyodbc module.

In the remoteplugin logs (and the UI) I'm getting an error that the module is not found:

     import pyodbc
 ModuleNotFoundError: No module named 'pyodbc'


Regardless of if I add only the Exasol Database python module or also the pyodbc module as a requirement in the plugin.json file. The module is not found:

"source": {
"package": "dynatrace_activegate_exasol_plugin",
  "className": "ExasolPluginRemote",
  "install_requires": ["pyodbc>=4.0.30","ExasolDatabaseConnector>=0.1.7"],
  "activation": "Remote"


I'm building the plugin in a python venv directly on the ActiveGate and the build/deployment succeeds. It seems that the pyodbc module creates some native libraries. Could that be a problem?

Here is the log (build_plugin.txt ) of the plugin build command.

Any ideas?

Hi Reinhard!

Try building plugin on Python3.6 venv instead on Python3.7 - native dependencies are not compatible with other minor versions, and we use Python3.6 to run extensions


Make sure that you use the 64 bit version of Python 3.6.


Hi Maciej,

thanks! I didn't think about that! Switching to python3.6 was the solution. I've switched my build docker container to 3.6 and that worked fine. Maybe that dependency is worth a note in the AG plugin documentation, since many distros are already switching to more recent versions of python. Especially since the documentation recommends to build directly on Activegates this might not be obvious to people.

Thanks again! My Exasol Plugin is on the way!

Reinhard, hello! Thanks for feedback! We actually mention it in the hands-on tutorial, but I agree this could be surfaced better. Will work on it.
