Error adding SofaPython3 and STlib plugin

[antonio.8196]

Hi, I downloaded the latest version of the SOFA binaries (20.12.03) and I wanted to open the Soft Robots tutorials, digging into the forum I saw that I needed to add the plugins from Sofa itself (since SOFa could not open .pyscn files) and I added the STlib plugin and the Soft Robots plugin but when I want to add the SofaPython3 plugin i get this message

Plugin loading failed (/home/einklugerjaeger/SOFAv20.12.03/SOFA_v20.12.03_Linux/plugins/SofaPython3/lib/libSofaPython3.so): libpython3.7m.so.1.0: cannot open shared object file: No such file or directory

I decided to install it from here but i get a similar error when trying to add the SofaPython3 plugin

Plugin loading failed (/home/einklugerjaeger/MySofa/SOFA_v20.12.00_Linux/plugins/SofaPython3/lib/libSofaPython3.so): libpython3.7m.so.1.0: cannot open shared object file: No such file or directory

I get a warning too when loading SOFA

Warning: Setting a new default format with a different version or profile after the global shared context is created may cause issues with context sharing.
The constructor with a QGLFormat is deprecated, use the regular contructor instead.

I have installed python 3.8, numpy and scipy as needed

einklugerjaeger@einklugerjaeger-VirtualBox:~$ python --version
Python 3.8.5

I have also a python2 package but as i showed above my default python version is 3.8, any help would be great! I am using xubuntu 20.0

I have already installed libopengl0

Hi @antonio-8196

You are using a SOFA binary which have been compiled using python3.7, you have the python3.8 installed on your machine.

You need to install the 3.7 version as stated here.

Best wishes

Hi @Hugo, thanks for the response,

Finally I just downloaded the binaries using my windows10 os but when I try to add the SofaPython3 plugin i get this error

My python dir is already in my path so i do not understand what is wrong here

Dear @antonio-8196

Have you set all path as explained here : https://sofapython3.readthedocs.io/en/latest/menu/SofaPlugin.html#within-a-python3-interpreter ?

Then run SOFA, load SofaPython, SoftRobots, and then STLIB ?

I want also to inform you that we are currently working hard on improving the installation of SOFA/SoftRobots/STLIB and providing better step-by-step documentation. This should be ready for the next release (end of June : v21.06). Sorry for the inconvenience.

Best wishes,

Hugo
