@ccaprani I don't know what is the issue with your built, but I confirm that, at my local openseespy.so built, both getEleClassTags() and getEleLoadClassTags() work correctly. @mhscott wrote elsewhere that the new official openseespy module will come soon.
Anyway I'm polishing an update of ops_vis, which among others, add a new plotting function (which uses getEleLoadClassTags() and getEleLoadData()): plot_supports_and_loads_2d() and the result would be:
And the output from the opensees functions are for example:
ele_load_tags_all_patterns: [1]
ele_load_types_all_patterns: [12]
ele_load_data_all_patterns: [-0.5, -1.0, 0.5, 1.0, 0.2, 0.8]
I still need to figure out the method to do the proper scaling of arrows for beams.

@sewkokot I love the teaser - those images look great indeed! I look forward to adding and supporting your development more in future.
I suspect that opensees.so from the normal installation was still somehow cached (even though i restarted the kernel etc). Do you mind sharing how you build the OpenSeesPy package - do you just initiate the build_pip.py script fully (which I didn't do)?
EDIT:
Found why the build with the new functions wasn't getting picked up: the Anaconda base environment was still active. Once switching to a new venv without openseespy installed it picks up the 'correct' module.
Unfortunately it seems the build wasn't successful with a strange import error:
ImportError: ../openseespylinux/opensees.so: undefined symbol: _ZN11LognormalRVC1EiRK6Vector
which using c++filt is from LognormalRV::LognormalRV(int, Vector const&): presumably this is a linker issue, but the make succeeded with no linker errors or warnings.

@ccaprani, I wish I had more time to work on the ops_vis library :)
Under Debian Sid linux, I use the following Makefile to build opensees.so module, which works and I don't get this _ZN11LognormalRVC1EiRK6Vector error with the latest OpenSees sources. I use only Debian python packages (no Anaconda), so I have no idea how to help more.

@sewkokot Thanks so much for sharing this - it gave me a lot to try but I'm still getting this undefined symbol.
At this point I think there is a bug in the python interpreter make system, at least for the version of the toolchain I am running, so I'll take it over to the OpenSees repo where there is an older issue on this I just found OpenSees/OpenSees#203.
In any case, it might help solving it if you could let me know the following:
What version is your ld --version? (mine is 2.36.1)
Would you kindly also let me know what dependencies your compilation has by running:
ldd ~/path/to/OpenSees/SRC/interpreter/opensees.soAnd would you mind letting me know if the same symbol appears in your library by checking:
readelf -Ws ~/path/to/OpenSees/SRC/interpreter/opensees.so | grep _ZN11LognormalRVC1EiRK6VectorYou use linker flag -rdynamic but it seems this is only relevant for executables? It doesn't seem to matter though.
Thanks!

Thanks for the remark on -rdynamic. It a remainder when I was converting tcl Makefile (executable) to python, at least it doesn't harm ;)
