Hello Everybody

First of all, I would like to thank @joelkallman-Oracle for this awesome article

I have tested running Python code from SQL Commands of the Early adopting instance. It is amazing!

However, I was wondering how to add Python's modules to MLE engine that would be used by APEX.

Say I have xyx module which is added by:

pip3 install xyz

Regards

Mahmoud

    Hi Mahmoud

    The APEX + MLE hosted preview is all about running JavaScript and Python code snippets in APEX. For deploying JavaScript and Python modules, we recommend to get our latest preview release of MLE (0.3.0): https://www.oracle.com/technetwork/database/multilingual-engine/downloads/index.html

    Note that our current support of running third party Python code is very limited (in contrast to third party JavaScript code that all should run fine), but we are working hard on it. Most third party Python modules cannot be used yet and, thus, we do not encourage users to try it out. However, if you really want to give it a try, here is how you can do it. Simply place the third party Python code (e.g., the module "aegon") in a directory "moduledeps" besides your own code (e.g., "myconv.py"). Finally, put everything into a single zip file and deploy it (see https://oracle.github.io/oracle-db-mle/python/). Here is one example that can be run in MLE 0.3.0:

    $ mkdir myconv
    $ cd myconv
    $ mkdir moduledeps
    $ pip install --target=./moduledeps aegon
    $ cat myconv.py
    from aegon import Measurement, Length
    def doconv(inch_in: float) -> str:
        distance = Measurement(inch_in, Length.inches)
        distance.convert_to(Length.meters)
        return str(distance)
    exports['to_meter'] = doconv
    $ zip -r myconv.zip *

    Best regards,

    Bastian
