    Hello SOFA community,

    I’ve been really struggling to use MOR plugin to refine my mesh as I am stuck in Phase 1: add animations to the actuators. In the beginning, I thought there were some problems with my code until I tried to run the code in /ModelOrderReduction/tools with the diamondRobot.py example scene. The error was the same!

PHASE 1 --- 3.387277126312256 seconds ---

    I looked into the output.log and it says: 

    [ERROR]   [PythonScript] SyntaxError: invalid syntax (phase1_snapshots.py, line 25)

    which is 

    originalScene = r'('/home/owen/Softwares/ext_plugin_repo/ModelOrderReduction/tools/sofa_test_scene/diamondRobot.py', 'Sofa Scene (*.py *.pyscn)')'

    I am guessing this could be a super trivial python problem because MOR was coded in Python2 and I am using Python3 in order to be compatible with PyQt5 (It was a lot of effort to rewrite the codes…) It seems like Python3 just doesn’t like this line, but I don’t really know why if it works with Python2. Can anyone suggest any solutions?

    Best regards,
    Owen

    Update: the syntax error seems to be fixed after I changed originalScene = r’$ORIGINALSCENE’ to originalScene = r”$ORIGINALSCENE” in the phase1_snapshots template.

    However, this ‘fix’ might not be correct as I got a new error: 

    ========= STDERR-LOG============

[ERROR]   [SofaPython] Script (file:phase1_snapshots) import error

    I have emailed Olivier for his opinion. Will update the post with his valuable suggestions.

    I let @felixvanneste reply to you on this one. I think he should be able to give you a good hint, but you might have to go back to Python2

    Hi @olivier-goury,

    Yes, I agree that going back to Python2 could solve the error. The only reason I choose to use Python3 is that I found it difficult to install PyQt4 with my current version of Qt5, while PyQt5 only supports Python3.

    If I understand it correctly, PyQt is for the GUI so it is essentially optional for the plugin. I am wondering if there is a no-GUI version of MOR that could let me avoid the usage of PyQt?

    Best,
    Owen

    Hi,

    I have resolved the problem by installing a Ubuntu 18.04 virtual machine. Now MOR is running smoothly. Thus I am going to close this post now. I want to go a big thanks to Olivier for returning to Python2 is the right thing to do to solve the problem.

    Best,
    Owen

    Hi everyone!

    Has anybody find a solution for this issue using Python3 and Qt5? =(

    I´m not really an expert on Python, but which could be the easiest way to go back to Python 2 and Qt4?

    Thanks in advance!

    Hi @agustinsantana

    Your question does not seem related to this post.
    Could you create a dedicated post please? Could you also in this new post specify the issue that you are facing (config, SOFA version, SofaPython3 version, error log etc)

    Thanks a lot in advance

    Hugo

    Hi @Hugo, sorry about the last question!

    My main issue is to know if somebody has solved this topic by using Python3 and Qt5, and not necessary using Python2 and Qt4 as @Owen did…

    Thanks again!
