Optuna dashboard crashes on MacOS

mspinaci commented 2 months ago

Expected behavior

The optuna db (generated on AWS, running linux) should be portable to my local machine (running MacOS).

Environment

Optuna version: 4.0.0
Python version: 3.10.13 (locally) and 3.11.9 (on AWS)
OS: MacOS 14.6.1 (locally) and Amazon Linux 2 (on AWS)
(Optional) Other libraries and their versions: Optuna dashboard version 0.16.2

Error messages, stack traces, or logs

I get a very long list of errors like:

(also a lot of annoying "Python stopped working" UI buttons I have to click through)

The same optuna SQLite file run with the same version of optuna-dashboard directly on AWS works fine.

Steps to reproduce

You can find the SQLite file generated by optuna causing the error at this link.

Additional context (optional)

No response

@mspinaci I tested optuna-dashboard (with gunicorn) on my Mac and it worked as expected. Unfortunately, for security purposes, I am unable to open your SQLite3 file though.

Could you possibly provide a minimal code example that reproduces your problem?

Please reopen this if you could prepare a minimal code example to reproduce this bug.
