Printer Stats plugin 2.0.0

Has anyone tried to update the Printer Stats plugin to version 2.0.0?
I tried all the possibilities (from the plugin manager, via the URL and the plugin manager, from an uploaded archive) and always the same problem.
The update fails systematically.
Thanks for your feedback.
Best regards

The problem is the Python version
2019-09-07 12:00:45,680 > RuntimeError: Python version >= 3.5 required.

This seems odd to me. Nowhere in the plugin's nor seems to demand Python 3. The actual plugin listing page indicates no compatibility concern.

What is your OctoPrint version? (Bottom of the page is where you'd find that.)

Thank you very much for your answer.
My Octoprint version is 1.3.11 (OctoPi 0.16.0)

Here is the listing of what is displayed during the plugin update procedure:

The update did not finish successfully. Please consult octoprint.log and plugin_softwareupdate_console.log for details.

I ran into this same error. It appears that the issue is that the newest version of numpy (1.17.2) requires python 3.5. I was able to get it working by pip installing numpy 1.16.5 (which is 2.7 compatible). That then allowed pandas-0.24.2 to install, which got the add-on to install.

Thank you very much for this information.
I will try this.

All is Ok now but I don’t see my previous stats !!!!

No sure there. I have my previous data. There is a filter drop-down at the top. Maybe that is set too narrowly?

I found my previous statistics.

In the ~/.octoprint/logs folder, I found the octoprint_stats.db.bak file.
After renaming octoprint_stats.db.bak file to octoprint_stats.db and restart octoprint, the octoprint_stats.db was converted to octoprint_stats.json.

My previous statistics are displayed again and now everything is really OK !!!!
