[SOLVED] Unable to load .py scene from SoftRobot plugin

[peter]

Dear forum members,

I have just downloaded the SOFA Windows binaries from this webpage:

Download

I am able to open SOFA on my computer, but whenever I try to open a scene from the documentation repository, I can’t launch any scene. For example, if I try to open “trunk.py”, I receive this message: extension (py) not handled.
How can I manage to launch this tutorial?

Thanks for any help you can provide.
Best regards,
Peter

Hi Peter,
the extension (py) not handled is usually caused by SOFA not finding the correct plugin to handle python files.

When starting SOFA (runSofa in /bin), go to Edit->Plugin Manager and make sure “SofaPython” is listed as a plugin. If that is not the case, click “Add” and and select libSofaPython.so from /lib.

Let me know if that fixes your problem.

Cheers,
Paul

Hi Paul,
Many thanks for you reply.
However, I cannot find any “libSofaPython.so” file.
There is a “SofaPython.dll” file in \bin, but when I try to add it through the plugin manager, it says the specified module cannot be found.
Any idea how to manage this?
Thanks again.
Peter

Hi Peter,
I just realized I did not catch that you are working with the windows version of SOFA.
There should be a SofaPython.lib inside of \lib.

Cheers,
Paul

I have found “SofaPython.lib” but using the plugin manager, I can only add “.dll” file. How can I add this plugin?
Thanks,
Peter

Hi Peter,
sadly I don’t have access to a windows computer, so I can’t really help you more on this.

Cheers,

hey @peter

could you try still using the downloaded binaries to:
– open SOFA
– open Edit->Plugin Manager
– select the library : in bin/SofaPython.dll provided with the binary of SOFA+SoftRobot for windows

This should work, do not hesitate to keep us posted.
Best,

Hugo

Hi Hugo,
Thanks for taking a look at my problem here.
I tried your instructions but got the following error message:
“Plugin loading failed C:/SOFA/SOFA_v19.06.99_custom_Win64_v8.1/bin/SofaPython.dll: specified module cannot be found”

I just realized that I also get this error message when I launch SOFA. When I launch runSofa.exe, it opens a terminal window where different messages are prompted, including this error message about SofaPython.dll not found.

Thanks again for your help.
Cheers,
Peter

Hey @peter

Have you installed python (2.7 here in your case) on you Windows ?
See the paragraph about Python here.

Hi, did anyone managed to solve this problem as i am having the exact same issue?

[Hugo]

Hi @anthony

Have you followed Paul’s and my advice?
If it does not solve your issue, could you – step by step – describe what is the problem when configuring/compiling/running SOFA ?

Hi Hugo, I am using SOFA 20.12 binaries for windows 10. i have python 2.7 installed but could not load the .dll file. below is the error message.

[ERROR] [PluginManager] Plugin loading failed (C:/Users/hl18924/OneDrive – University of Bristol/Documents/PHD/Trustworthy robots/SOFA_v20.12.00_Win64/plugins/SofaPython/bin/SofaPython.dll): The specified module could not be found.

I am not a core developer but maybe this helps: Go to Edit-> PluginManager and then select Sofapython dll in the plugins/SofaPython/bin directory

[Hugo]

Hi @anthony

You can follow Chris advice. The error seems to assume that the dll is not in the given path. Can you see it?

I am still unable to make it to work so have bult sofa from source on ubuntu. Seems to work ok-ish but the softrobot plugin is still a bit broken from the python3 migration.

Hi @anthony

Shall we close this topic ?

Hugo

[Anthony]

Yes, please. Thanks
