[SOLVED] Help! Model order reduction – ‘can’t find anything to animate’

[Owen]

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:

[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

[Owen]

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

Ok perfect! Do not hesitate to come back to us if you run into further issues.

Cheers,
Olivier

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!

[Hugo]

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

[Agustin Santana]

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!
