@dosubot[bot] commented on GitHub (Oct 16, 2024):

To resolve the "No module named 'schedule.clean_embedding_cache_task'" error when running a Celery worker in Dify version 0.9.2, follow these steps:

  1. Verify Module Existence: Ensure that the schedule directory exists and contains a file named clean_embedding_cache_task.py. This file should define the task clean_embedding_cache_task [1].

  2. Check Python Path: Make sure that the directory containing the schedule module is included in your Python path. You can check this by printing sys.path in your script or by setting the PYTHONPATH environment variable.

  3. Correct Import Path: If the module is located in a different directory, adjust the import path accordingly in the Celery configuration.

  4. Install Required Packages: If schedule is part of an external package, ensure it is installed in your environment.

These steps should help you resolve the import error and get your Celery worker running correctly.

Sorry, I found the cause of this problem, somehow I installed a python package called schedule which caused this problem.
