Hello, My suite ‘u-cm987’ fails on the ‘flight\_track\_sim’ task because the ‘iris’ library is not available. I sought help from archer2 admin and they confirmed my miniconda3 environment is set up correctly. I also ran the command: conda install -c conda-forge cis to make the python ‘iris’ library available. The first line of the associated python script is #!/work/n02/n02/lre/miniconda3/bin/python This would be far easier if iris were commonly available. But, since it’s not could you please explain how I could make sure the task sees the correct miniconda environment? Thanks very much, Leighton ---

Hi Leighton, Try setting the PYTHONPATH for the task to point to your miniconda3. At the moment you’re still loading the cray-python 3 environment for the task. A central IRIS install is on our list of todos. Regards, Ros. ---

Hi Ros, I’m not sure if I’ve implemented your suggestion correctly. I changed the PYTHONPATH for this task in my archer2.rc file to be PYTHONPATH=/work/n02/n02/lre/miniconda3/bin/python Is that what you meant? I reran with that chage and iris is still not visible. Thanks, Leighton ---

Hi, Try using `#!/work/y07/shared/umshared/iris/python` at the start of your script. Simon. ---

Hi Simon, Thanks for the suggestion. Is this a test version of a shared iris library? The flight\_track\_sim task now crashes with multiple errors related to missing python functionality. It doesn’t seem to be able to import, try or use loops. Thanks, Leighton ---

Hi Leighton, It’s iris 2.3.0 Unfortunately there is an issue with my previous answer, try `#!/usr/bin/env python_iris` instead. And, if you have the `pre_scipt` option set in the `FLIGHT_TRACK_RESOURCE` config in `site/archer2.rc`, please remove it.
