Upgrade to 1.9.0 restore from backup

What is the problem?

Upgraded a fresh install to OctoPrint 1.9RC6 yesterday and restored a backup from another install. I uploaded a gcode from PrusaSlicer and I see "Model contains no extrusion.".
When I look at the log for PrintTimeGenuis, it is still looking for python3.7 when it is now running 3.9.
Exception: /home/pi/oprint/bin/python3: can't open file '/home/pi/oprint/lib/python3.7/site-packages/octoprint_PrintTimeGenius/analyzers/analyze_gcode_comments.py': [Errno 2] No such file or directory

What did you already try to solve it?

I've changed
"/home/pi/oprint/bin/python3" "/home/pi/oprint/lib/python3.7/site-packages/octoprint_PrintTimeGenius/analyzers/analyze_progress.py" marlin-calc "{gcode}" "{mcodes}"
To
"/home/pi/oprint/bin/python3" "/home/pi/oprint/lib/python3.9/site-packages/octoprint_PrintTimeGenius/analyzers/analyze_progress.py" marlin-calc "{gcode}" "{mcodes}"
In PrintTimeGenius settings, won't know if this has worked until it has stopped printing.

Have you tried running in safe mode?

No.

Did running in safe mode solve the problem?

Don't know.

**Describe the bug** After migrating my system to a new Pi and updating to the …newest version of Octopi with it, I could not get accurate time estimates or filament usage in Octoprint. I later tracked down the issue to PrintTimeGenius failing to run, with the issue being it was pointing to the old version of the python venv (python3.7) rather than the new one (python3.9). I did have to manually call the restore function via command line, but I am not sure if that would have changed the result since the issue seems to be how the settings are saved. **To Reproduce** Steps to reproduce the behavior: 1. Backup Octoprint configuration from Octopi image <= 0.18.0 with PTG installed. 2. Reflash Pi to OctoPi v1.0.0 (RC2 is current release). 3. Restore Octoprint configuration. 4. Upload new file and PTG will fail to run with the following message: ``` Traceback (most recent call last): File "/home/pi/oprint/lib/python3.9/site-packages/octoprint_PrintTimeGenius/__init__.py", line 339, in _do_analysis raise Exception(results_err) Exception: /home/pi/oprint/bin/python3: can't open file '/home/pi/oprint/lib/python3.7/site-packages/octoprint_PrintTimeGenius/analyzers/analyze_progress.py': [Errno 2] No such file or directory ``` **Expected behavior** I would expect the paths that PTG saves would be agnostic to where the "oprint" python venv is located. Perhaps there is a way to save the command with some sort of variable that changes based on the location of the venv or simply uses relative paths. Manually updating the command string to read python3.9 fixes the issue and allows the plugin to run. **OctoPrint Version:** 1.8.2 (OctoPi 1.0.0 RC2, unsure if this is only an octopi thing) **PrintTimeGenius Version:** 1.28.0
