Tasks Troubleshooting

Troubleshooting tasks

This is intended only for IVIS instance admins with direct access to the server.

Manual activation of the Python environment

In the /server/files/task-content folder, there are folders with code and environment for all the tasks. Each task has its own separate folder marked by its ID. In the task folder, there is a dist folder with the task code in job.py and an env folder with the Python virtual environment.

The setup of the virtual environment was run in a different directory and the libraries were copied here. So before one can activate the environment, it has to be re-initialized using /usr/bin/python3 -m venv env. After that, one can activate the environment by running source env/bin/activate and then install libraries and pip packages manually.

Recompilation of the ivis package

If one updates the code of the ivis package and it does not update automatically in the task directory, it can be updated manually.

One should be able to initialize the update by running

pip install --no-index --upgrade --find-links="/ivis-core/server/lib/tasks/python/ivis" ivis

in the virtual environment with --find-links set to correct path to the IVIS instance installation.

If that doesn't help, the files of the ivis package can be manually copied to the directory as the package doesn't require any special installation. The code of the library can be found in /server/lib/tasks/python/ivis. In the task virtual environment (env directory), the library is saved in lib/python3.6/site-packages/ivis (with possibly different version of Python than 3.6).
