Third party library python-keycloak doesn't work

[Marcos_Verdugo]

I installed the python-keycloak library in my host PC using "pip install python-keycloak", I made my tests outside ignition and everything works fine. Once I tested everything I tried to do it inside Ignition scripting. I downloaded the files from the library and pasted the folder under ...user-lib/pylib.

I copy and pasted my previously tested code on a scripting action by a button. I tried to execute the script by I always have an error. Is there any way of importing a third party library from python into ignition and that it actually works just as it does outside ignition?

I am running Ignition 8.1.45

@inductiveautomation , is there any plans to have an updated Jython version implemented in Ignition? Which would be a java based implementation of Python 3.x?

java based implementation of Python 3.x?

Jython 3 doesn't yet exist. Even if it did, it would not be able to load the C-library based extension modules that are so popular in CPython. (like numpy)

Python version 3 update?

I guess I can paraphrase what I said on stage at the dev panel at this year's ICC, for posterity and so I can link to this in the future: So, the question people usually ask is "When is Python 3 coming to Ignition?". But in practice, there's really two broad reasons people are actually asking that question: They've heard that Python 2.7 is deprecated/old/unmaintained/a security risk/whatever. But that doesn't apply to Ignition, for a few reasons: When folks say "Python" out in the world, the…

Thank you!
Your write-up answered my questions I had. Very complete answer and I am satisfied with the reasons. I can now share this thread when I am asked about this subject.
