Error upon installation

[Sinasta]

Hello, thanks for your work. I'am getting this error when i try to install your addon on arch linux (manjaro). I am using python 3.9 and blender 3.0 with a system installation (means blender is using my systems python packages instead of its own).

Traceback (most recent call last): File "/usr/share/blender/3.0/scripts/modules/addon_utils.py", line 330, in enable importlib.reload(mod) File "/usr/lib/python3.9/importlib/init.py", line 169, in reload _bootstrap._exec(spec, module) File "", line 613, in _exec File "", line 850, in exec_module File "", line 228, in _call_with_frames_removed File "/home/sinasta/.config/blender/3.0/scripts/addons/topologicsverchok-main/init.py", line 40, in topologicEggName = '/'+[name for name in os.listdir(win_prefix+'/topologicPy/site-packages') if name.startswith('topologic')][0] FileNotFoundError: [Errno 2] No such file or directory: '/home/sinasta/.config/blender/3.0/scripts/addons/topologicsverchok-main/topologicPy/site-packages'

[wassimj]

Can you please tell me what files you have in

/home/sinasta/.config/blender/3.0/scripts/addons/

[Sinasta]

[wassimj]

Can you then please check if the following folder exists /home/sinasta/.config/blender/3.0/scripts/addons/topologicsverchok-main/topologicPy/site-packages

[Sinasta]

Sure. thanks for your help. the folder does not exist:

ls /home/sinasta/.config/blender/3.0/scripts/addons/topologicsverchok-main

examples LICENSE pycache topologicsverchok.zip init.py nodes README.md

[Sinasta]

my topologicpy is in: /usr/lib/python3.9/site-packages/topologic-0.5-py3.9.egg

[wassimj]

Right, then just copy the egg to /home/sinasta/.config/blender/3.0/scripts/addons/topologicsverchok-main/topologicPy/site-packages

[Sinasta]

Thanks this worked somehow. But now i get this error when trying to activate:

Traceback (most recent call last): File "/usr/share/blender/3.0/scripts/modules/addon_utils.py", line 351, in enable mod = import(module_name) File "/home/sinasta/.config/blender/3.0/scripts/addons/topologicsverchok-main/init.py", line 244, in imported_modules = make_node_list() File "/home/sinasta/.config/blender/3.0/scripts/addons/topologicsverchok-main/init.py", line 239, in make_node_list module = importlib.import_module(f".{module_name}", base_name) File "/usr/lib/python3.9/importlib/init.py", line 127, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "/home/sinasta/.config/blender/3.0/scripts/addons/topologicsverchok-main/nodes/Topologic/VertexByCoordinates.py", line 8, in faulthandler.enable() AttributeError: 'LogFile' object has no attribute 'fileno'

[wassimj]

Sorry not sure what this is. I will ask Linux experts.

[brunopostle]

There was a similar error caused by a bug in the last blenderbim release, what version of blenderbim have you installed? You may need to download it again.

Note that if you have managed to get the latest Homemaker add-on working, then you already have a working topologicPy, all you need is sverchok and the topologic-sverchok add-on. Check that you don't have conflicting versions installed.

An unexpected thing about the blender python interpreter is that it doesn't pick up libraries installed in ~/.local so python code needs to be installed system-wide or bundled with the add-on.

[Sinasta]

Thank you for your help! i installed the latest ifcopenshell release and updated to your latest homemaker release just in case. But i still get the same error.

[wassimj]

Please go into the addons folder of Blender then into topologicsverchok/nodes/Topologic and edit Vertex.byCoordinates.py and comment out around line 8 where it is calling faulthandler.

[wassimj]

To comment in python add a # at the start of the line

[Sinasta]

now i get this error:

Traceback (most recent call last): File "/usr/share/blender/3.0/scripts/modules/addon_utils.py", line 351, in enable mod = import(module_name) File "/home/sinasta/.config/blender/3.0/scripts/addons/topologicsverchok-main/init.py", line 244, in imported_modules = make_node_list() File "/home/sinasta/.config/blender/3.0/scripts/addons/topologicsverchok-main/init.py", line 239, in make_node_list module = importlib.import_module(f".{module_name}", base_name) File "/usr/lib/python3.9/importlib/init.py", line 127, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "/home/sinasta/.config/blender/3.0/scripts/addons/topologicsverchok-main/nodes/Topologic/EnergyModelByImportedOSM.py", line 6, in import openstudio ModuleNotFoundError: No module named 'openstudio'

[wassimj]

Yes. Please install openstudio using “pip install openstudio” and then copy the installed openstudio folder to the same addons folder next to BlenderBIM and topologicsverchok etc

[Sinasta]

Now it worked! thank you very much.

[Sinasta]

After the latest update i get this error when trying to activate topologic sverchok:

Traceback (most recent call last): File "/usr/share/blender/3.2/scripts/modules/addon_utils.py", line 351, in enable mod = import(module_name) File "/home/sinasta/.config/blender/3.2/scripts/addons/TopologicSverchok-main/init.py", line 56, in import topologic ImportError: generic_type: type "TopoDS_Shape" is already registered!

I tried deactivating my other addons but this didnt help. The import of topologic works though when done in python-console in the site-packages/topologic/ directory of the addon.

[wassimj]

Please tell me the version of topologic or the date of the ZIP file (latest is 2022-02-06) and please run the following script in the console and give me a screenshot on it:

from topologic import Vertex
v = Vertex.ByCoordinates(10,20,30)
print(v.X(), v.Y(), v.Z())

TopDS_Shape is the main OCCT shape that is also used by FreeCAD. So I suspect it is still a clash with FreeCAD. Also, make sure topologic is removed. Then make sure you restart Blender and install a fresh copy. I have seen the above error at times when you deactivate and then try to re-activate Topologic in the same session. If you deactivate Topologic, you have to quite Blender and restart it.

[Sinasta]

Thank you for your answer. The zip version is the lateste one (2022-02-06). I tried a new fresh install but it gives me the same error message. Topologic works well in the directory of topologic.so but in the blender console it doesnt. I supposed aswell the error coming from freecad being loaded as a dependency of sverchok but i deactivated freecad beeing loaded.

[wassimj]

Do you have homemaker installed and active by any chance?

[brunopostle]

[from a previous bug report] @sinasta is using the equivalent versions of Topologic and Homemaker.

Though for users who have the full version of Topologic Sverchok, there is a 'noarch' version of the Homemaker add-on that doesn't contain the duplicated libraries, and which avoids potential problems like this: https://github.com/brunopostle/homemaker-addon/releases

[Sinasta]

I indeed use Homemaker but i already tried and removed it. I don't really know what else could cause the interaction.

[wassimj]

ok. I will launch my Ubuntu partition and test it. @brunopostle can you test TopologicSverchok on your linux machine as well? Thanks! I know it works on Windows, but maybe I missed something on Linux. Will report back.

[wassimj]

Hi @Sinasta and @brunopostle. I just installed TopologicSverchok 0.7.0.2 on Linux Ubuntu 20.10 and Blender 3.0 with sverchok and I did not encounter any errors. Please see screenshot below.

I suggest you open the Blender scripts folder (e.g. ~/.config/blender/3.0/scripts/addons) and make sure you remove any references to Homemaker or Topologic (perhaps there is a previous version left over) and try again. If that works, then install the noarch version of Homemaker.

[Sinasta]

I tried a complete new install of topologic and topologicsverchok. I removed topologicsverchok and homemaker from blender( i veryfied in the addon folder) i uninstalled freecad(just in case). than i followed the procedure you explained here: https://github.com/wassimj/Topologic/issues/31 . I tried to install the topologic sverchok addon afterwards with the newly build topologic.so in the site-packages folder but still i got the same error. It might be worth noting that my blender version is 3.2, python 3.10.2, opencascade 7.5.3 and blenderbim 0.0.220209

[Sinasta]

i dont really know enough but is there maybe a way to check in the blender console what registered "TopoDS_Shape"?

[Sinasta]

i have some packages installed with pip to the blender/3.2/scripts/modules folder, they get loaded when blender starts:

pip list --path $HOME/.config/blender/3.2/scripts/modules Package Version

[wassimj]

Topologic is only compatible with opencascade 7.4.2. Please try the precompiled binaries rather than build it yourself https://github.com/wassimj/TopologicSverchok/releases

[brunopostle]

@Sinasta I think what you have done should work: if you have compiled Topologic with python 3.10.2 and opencascade 7.5.3 that are installed system wide, then you should be able to remove all the .so files in the Topologic-Sverchok add-on folder and replace them with the topologic.cpython-310-x86_64-linux-gnu.so file that you built yourself.

The "TopoDS_Shape is already registered" error suggests that you still have conflicting versions of Topologic installed somwhere.

[wassimj]

On Linux, Topologic.so files usually end up in /usr/local/lib. Perhaps you have a version installed there and it is conflicting with the one you are trying to use.

[Sinasta]

I have indeed some topologic files in /usr/local/lib: libTopologicCore.so libTopologicCore.so.0 libTopologicCore.so.0.0.0

and some in /usr/local/include/TopologicCore: About.h Dictionary.h PlanarSurface.h ApertureFactory.h DoubleAttribute.h ShellFactory.h Aperture.h EdgeFactory.h Shell.h Attribute.h Edge.h StringAttribute.h AttributeManager.h FaceFactory.h Surface.h Bitwise.h Face.h TopologicalQuery.h CellComplexFactory.h Geometry.h TopologyFactory.h CellComplex.h GlobalCluster.h TopologyFactoryManager.h CellFactory.h Graph.h Topology.h Cell.h InstanceGUIDManager.h Utilities ClusterFactory.h IntAttribute.h Utilities.h Cluster.h Line.h VertexFactory.h ContentManager.h ListAttribute.h Vertex.h Context.h NurbsCurve.h WireFactory.h ContextManager.h NurbsSurface.h Wire.h

But when i rename the 3 files in /usr/local/lib to *.bak topologic sverchok gives an error: ImportError: libTopologicCore.so.0: cannot open shared object file: No such file or directory

thats why i assumed they where important. My case might be different to others because i have manjaro linux (arch based) and blender is using my systems python(no bundled python).

[brunopostle]

@Sinasta that's ok, I'm using the blender 3.0 shipped with fedora that is linked with the system python 3.10.

You need the libTopologicCore.so* files in /usr/local/lib this is the non-python part of Topologic.

The .h files are not used at run-time.

The Topo_DS error implies that you have multiple versions of Topologic and/or opencascade somewhere.

[wassimj]

So if the conflict is not with the C++ libraries, but with the python bindings, find out if there is a second topologic python module installed in your system's python site-packages or dist-packages folder or similar. I suggest you issue the following command and then search the displayed folders to see if there is duplication:

python -m site and python -m site --user-site

[Sinasta]

I finally realised what was causing the issue. i thank both of you very much that you helped me even though it was clear that it was not a general issue. I have an addon installed which is called VI-suite. If you don't already know it than it is defenitly worth taking a look at. It uses Radiance, energy+ and openfoam to perform parametric environemental analysis (somehow similar to the ladybug suite). Anyways, for the airflow analysis it relies on openfoam which uses netgen to convert the mesh. Netgen seems to be causing the interaction in my case.

[wassimj]

That is quite the investigation! Glad you found it. Netgen seems to be using something similar to pythonocc (https://github.com/tpaviot/pythonocc)
