Common Issues

Python related

1. Newly updated ET shows an error at startup

   ET caches your last configuration for each application you use. Sometimes we make changes to the applications in ET, which makes the cache invalid.

   If you face any issues, you can run the command

   python -m acconeer.exptool.app --purge-config
   

   to remove the invalid cache.

2. Import errors with NumPy on Linux

   The solution is to remove all duplicates of NumPy and reinstall using pip:

   sudo apt remove python3-numpy
   python -m pip uninstall numpy       # Repeat until no NumPy version is installed
   python -m pip install --user numpy
   

   Depending on your environment, you might have to replace python with python3 or py.

3. The GUI does not load properly after updating

   Try running python -m acconeer.exptool.app --purge-config from anywhere. Accept the removal of the files and try starting Exploration Tool again.

   If the above does not work, please open an issue on GitHub.

4. The GUI does not start and shows an error: qt.qpa.plugin: Could not find the Qt platform plugin "windows" in "".

   This error have been witnessed when Exploration Tool is installed in an Anaconda environment. The error may also occur when there are non-ASCII characters in the path.

5. Dropdown menu is out of position

   This is a known issue on for Qt when running Wayland display server. The issue is fixed for Qt version >= 6.4.0. (See related issue: https://bugreports.qt.io/browse/QTBUG-85297)

6. malloc_consolidate(): unaligned fastbin chunk detected appears in the console when running ET

   This error has been witnessed when running ET on Ubuntu 22.04. The error is usually resolved by selecting Ubuntu on Xorg instead of Ubuntu in the Ubuntu login screen (by pressing the cogwheel in the lower right).

7. Issues with nox tests for Python 3.12

   When running nox tests for Python 3.12, the error AttributeError: module 'pkgutil' has no attribute 'ImpImporter'. Did you mean: 'zipimporter'? might occur. To fix this run python -m virtualenv --upgrade-embed-wheels to upgrade virtualenv’s packages.

8. Problems with downloading latest binary when flashing

   Downloading the latest binary depends on the Acconeer developer site. Update to latest version of Exploration Tool.

9. Cannot unpack GitHub zip on Windows

   The root issue is the MAX_PATH setting on the Windows platform. Try unzipping the zip in a place that’s not at deep in your folder structure. To your Desktop, for example.

10. Cannot open recorded h5-files on newly updated ET

    If you get an error when trying to replay a file in ET; you have probably recorded the data with an older version of ET. Try opening the file with the same version of ET as it was recorded with. For example, in Distance Detector you might get the error Could not start, Not ready to start (CONFIG_MISMATCH) when trying to replay an old file. You can find out which version the h5-file was recorded with by running the script:

    examples/a121/load_record.py <your h5-file>
    

    which will output the “ET version”: .. code-block:

    ET version:  <the ET version that created the h5-file>
    RSS version: <the RSS version used when creating the h5-file>
    HW name:     xc120
    Data shape:  (256, 1, 439)
    ...
    

    Then you can try installing that version (pip install acconeer-exptool==<the ET version that created the h5-file>) and replaying the file.
