FilamentManager Plugin install issue / Windows

What is the problem?

Installation of FilamentManager Plugin on a Windows setup "fails" => successful installation messages, but plugin isn't found / visible after OctoPrint restart.

What did you already try to solve it?

  • Installing manually from command line
  • Switching Octoprint from official 1.4.2 to 1.5.0rc3 to try to install through UI
  • installing the dev version of the plugin (0.5.3, previous github repo) instead of the official one on "new" repo OllisGit.

The latter provides this message, thus I kept trying installing the official release

Have you tried running in safe mode and if so did it solve the issue?

I didn't, since it's about a plugin.

UI Install: Success message but plugin is named "Unknown" + error in console logs

Manual install: Success message

Both install methods provide the same result: plugin isn't found

Additional information about your setup

Octoprint 1.4.2 => 1.5.0rc3
Win10 / Edge
Python 3.9.0 / pip 20.2.4

I'm trying to install this FilamentManager plugin as a dependency of PrintJobHistory

Thanks for your help or advice to get clean Print logs on a Windows Octoprint setup

Hello @Nagash!

I assume you uninstalled the obsolete version beforehand?

Hi @Ewald_Ikemann,

Yes indeed, I uninstalled from CLI the previous version each time, since I can't see it in the UI

Looks like a problem in a dependency of the plugin, that is incompatible with Python 3.8 and newer, you are running 3.9. From octoprint.log:

File "c:\octoprint\venv\lib\site-packages\octoprint_filamentmanager\", line 17, in <module>
    from .data import FilamentManager
  File "c:\octoprint\venv\lib\site-packages\octoprint_filamentmanager\data\", line 13, in <module>
    from sqlalchemy.engine.url import URL

  File "c:\octoprint\venv\lib\site-packages\sqlalchemy\util\", line 172, in <module>
    time_func = time.clock
AttributeError: module 'time' has no attribute 'clock'

From the Python 3.7 time documentation

Deprecated since version 3.3, will be removed in version 3.8

The dependency SQLAlchemy is probably pinned that low for Python 2 compatibility (although I haven't looked), I recommend opening an issue on the github repository so that @OllisGit is aware and can fix it.

Hi @Charlie_Powell ,

thx a lot for analysing the issue!!!

It doesn't look so good, it will take a lot of effort to make the plugin Python 3.8 ready.
For the records here is the plugin-issue link:
