Just upgraded to 1.72.1 (from 1.65), and I was very much looking forward to the "Manage Interpreters" function in the Admin menu, and it's just not there. Running Enterprise Matillion and I verified my user group had Scripting permissions (Get Interpreter / Add Interpreter). I can open a ticket with support but just wanted to see if anyone else has had the same issue. ---

Addendum... I was desperate for the feature this today. Not seeing it, I did some manual changes to add some packages to Python 3.8 and I changed the python3 link to point to Python3.8 for good measure, and then I changed a big heap of Python Script components to use Python 3.8, and everything was working brilliantly. I then made a change to Emerald.properties to add the Performance Monitor and rebooted, and when the server came pack, Python 3.8 was no longer a valid interpreter (in fact, I previously had 3.5, 3.6, 3.6m and more -- but now the pull down only showed Jython, Python 2, and Python 3 -- and Python 3 had permission issues when I tried to run a script with that interpreter). This was an instance I built from scratch a couple of days ago, and I'm likel going to start up a whole new instance from scratch over the weekend and try again. I could have really used that function. 😊 ---

Ok, I've now discovered that when I add FEATURE\_SWITCHES=PERFORMANCE\_MONITOR to Emerald.properties, it disables the Manage Interpreters Admin menu item. Is this the expected behavior? ---

This issue is still not resolved for us also we faced the issue. ---

Did you ever get a response to this? I think the same thing happened to me today when I turned on FEATURE\_SWITCHES=PERFORMANCE\_MONITOR. It seems odd that Manage Interpreters disappears when the performance monitor is turned on. I wonder if that is a "feature".     ---

Yeah, never got a reply. Unfortunately, it's a feature I'll never use in the real world because it instantly breaks my python script components set to work with Python 3.8. I would love to have more clarity about it's behavior and intended use.
