1581537 : Regarding help to open piFAI from maxwell

Created: 2026-03-04T10:35:41Z - current status: new

Here is the anonymized and summarized version of the reported issue:

Summary of the Issue

A user attempted to load the pyFAI module on the Maxwell cluster using the following commands:

module load maxwell pyFAI/2025.3
module load maxwell pyFAI

However, no application or interface opened after executing these commands.

Possible Solution

The module load command only sets up the environment for pyFAI but does not launch a graphical or interactive interface by default. To use pyFAI, the user should:

  1. Check available versions (if unsure which version to use): bash module avail pyFAI (Example output: pyFAI/0.20.0, pyFAI/0.21.3, pyFAI/2023.1)

  2. Load the desired version (e.g., pyFAI/2023.1): bash module load maxwell pyFAI/2023.1

  3. Verify the installation by running a Python command: bash python3 -c 'import pyFAI; print(pyFAI.version_info[0:3])' (Expected output: e.g., (2023, 1, 0))

  4. Use pyFAI tools (e.g., pyFAI-calib for calibration): bash pyFAI-calib (This should launch the graphical calibration tool.)

  5. Alternative: Use Conda environment (if needed): bash module load maxwell conda/3.9 . mamba-init mamba activate pyFAI pyFAI-calib

Notes

  • The version pyFAI/2025.3 does not appear in the available modules (as of the provided context). The user may need to use a supported version (e.g., pyFAI/2023.1).
  • If the issue persists, the user should check for error messages in the terminal or consult the pyFAI documentation.
