Hi, Sofa Forum,
In recent days, I use SofaPython3 to
some error occurs.
my sofa root is :/home/cmx/sofa, SofaPython3 root is /home/cmx/SofaPython3.
I use the out-of-tree-build following the guidance in the forum. All files are compiled successfully in Cmake-gui. Because SofaPython3 needs python3, so i establish conda environ with python3.8 to compile and succeed.
When run the following in virtual environ:
./$SOFA_BLD/bin/runSofa -l $SP3_BLD/lib/libSofaPython3.so,
errors:(base) cmx@cmx-Lenovo-IdeaPad-Y510P:~/sofa/build/bin$ ./runSofa -l /home/cmx/SofaPython3/build/lib/libSofaPython3.so [INFO] [runSofa] PluginRepository paths = /home/cmx/sofa/build/plugins:/home/cmx/sofa/build/lib [INFO] [runSofa] DataRepository paths = /home/cmx/sofa/src/share:/home/cmx/sofa/src/examples [INFO] [runSofa] GuiDataRepository paths = /home/cmx/sofa/src/applications/projects/runSofa/resources:/home/cmx/sofa/src/modules/SofaGuiQt/src/sofa/gui/qt/resources [INFO] [SofaPython3] Initializing with python version 3.8.3 (default, Jul 2 2020, 16:23:49) [GCC 7.3.0] [INFO] [SofaPython3] Registering a scene loader for [.py, .py3, .pyscn, .py3scn] files.

however, no libSofaPython3.so.1.0 file compared with sofa forum.
Another question, before using SofaPython3, I use SofaPython, however, when runcmx@cmx-Lenovo-IdeaPad-Y510P:~/sofa/build/bin$ python Python 2.7.17 (default, Jul 20 2020, 15:37:01) [GCC 7.5.0] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import Sofa Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: No module named Sofa >>>I dont know how to import Sofa in Python environment.
Please give me some help. I was hoping someone could clear up the confusion.Hi Cai,
About SofaPython3 and Conda the problem seems to be at the initialization of the plugin (where we initialize the python3 interpreter). Maybe, but it is only a guess, there is a mismatch between the version you use for compilation and the one shipped with Conda. On my computer I tend to only use apt and pip3 to install python packages. Each time I tried to use conda it generate a lot of mess so I just gave up. But If you success please tell us.
SofaPython3 is now an official plugin from the sofa-consortium…the new official (and updated) repository is now https://github.com/sofa-framework/SofaPython3
About the question related to old SofaPython. It is not possible to use it in a python environment because the python Sofa modules and the python interpreter are compiled together. So the only way is to use it is to load a Sofa scene with runSofa and do the code there using the python interpreter included in the plugin SofaPython.
