Upgrade to python3

[santteegt]

Hi,

I'm looking for ways to upgrade the system so a Python Transformer can execute python3 code instead of python2.7. I've tried updating the version of conda and setting the python version used by pyspark within the sessionmanager container, but then I can't initiate any workflow due to an error in the PythonExecutionCaretaker class. What steps should I take to enable Python3 within Seahorse transformer operators?

Thanks for your advice

Hi @santteegt
Were you able to figure out a fix for this issue?

[subinsoman]

change the code in seahorse-workflow-executor/blob/master/python/pyexecutor/code_executor.py

exec custom_operation_code in context

to

exec (custom_operation_code in context)
