From de93781607e7a079935c412d03a600876fd669ce Mon Sep 17 00:00:00 2001 From: karajan1001 Date: Tue, 27 Sep 2022 16:08:30 +0800 Subject: [PATCH] Use celery status as the exp show status fix: #8349 `tasks status turned to queued for 1 second before turned into success.` is because in previous the status is using the output of `get_running_exps` in `repo.expereiments` and when entering the collect result progress, the `get_running_exps` will mark the tasks to be not running because the `info.result` is not None. Here we use the output of the celery queue as the universal standard for the tasks status. 1.
