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

from topologicsverchok.

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

from topologicsverchok.

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

from topologicsverchok.

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

from topologicsverchok.

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

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

from topologicsverchok.

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.

from topologicsverchok.

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.

from topologicsverchok.

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.

from topologicsverchok.

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

from topologicsverchok.

now i get this error:

from topologicsverchok.

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

from topologicsverchok.

Now it worked! thank you very much.

from topologicsverchok.

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.

from topologicsverchok.

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.

from topologicsverchok.

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.

from topologicsverchok.

Do you have homemaker installed and active by any chance?

from topologicsverchok.

from topologicsverchok.

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

from topologicsverchok.

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.

from topologicsverchok.

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.

from topologicsverchok.

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: wassimj/Topologic#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

from topologicsverchok.

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

from topologicsverchok.

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

from topologicsverchok.

@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.

from topologicsverchok.

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.

from topologicsverchok.

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).

from topologicsverchok.

@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.

from topologicsverchok.

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

from topologicsverchok.

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.

from topologicsverchok.

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