@Marvin what can be the reason for

ModuleNotFoundError: No module named '__prefect_loader__

when cached results are trying to be read?

One possible reason for encountering the

ModuleNotFoundError: No module named '__prefect_loader__'

error when attempting to read cached results could be related to the Python environment or the installation of Prefect. It sounds like an installation-related issue, possibly due to the way Prefect is installed or an inconsistency in the environment. Here are some common troubleshooting steps that might help: 1. Check your installation: Ensure that Prefect is installed properly in your environment. An editable installation (using

pip install -e

) is recommended if you are working on the development version of Prefect (Installation Guide). 2. Verify your Python environment: Make sure that you are running your code in the Python environment where Prefect is installed. It is common for such errors to occur when there are multiple environments and the active environment does not have Prefect installed. 3. Update Prefect: Be sure that you are running the latest version of Prefect, as some issues are resolved in newer releases. You can update Prefect by running

pip install --upgrade prefect

. 4. Check Prefect's documentation related to result handling and caching: Look for any specific instructions regarding cached results that might mention dependencies or additional configuration that could be implicated in the error (Concepts: Results). 5. Review Prefect's troubleshooting guide: Consult the troubleshooting guide to see if this is a known issue, or if there are other recommended steps to resolve similar problems. If the issue persists, consider providing more context or reviewing any recent changes that could have led to this problem.
