Hi McNeel, Both GHPython components that ship with Rhino 8.4.24023.15001 break when running in SDK mode: [2024-02-05 12_50_34-Grasshopper - unnamed] Best, Anders

@AndersDeleuran Find this file: %APPDATA%\McNeel\Rhinoceros\8.0\Plug-ins\IronPython (<id>)\settings\lib\ghpythonlib\__init__.py where <id> is some guid string. Replace the contents with this and reload Rhino: # ghpythonlib package __all__ = ["components", "treehelpers", "parallel", "componentbas…

[Rhino_FCkdzyUVaZ] I just installed the latest 8.4 and can not replicate the issue. Would you mind clearing the %appdata%\\McNeel\Rhinoceros\8.0\Plug-ins\IronPython (** cache and let RhinoPython install the libraries again. Also it might be a conflict with the new IronPython. Try disabling Rhino…

I just updated to 8.4 too and afraid it doesn’t resolve my issue: [image] Ehsan Iran-Nejad: Would you mind clearing the %appdata%\\McNeel\Rhinoceros\8.0\Plug-ins\IronPython (** cache and let RhinoPython install the libraries again. I couldn’t find that exact folder, but tried deleting this o…

Looks like it is the same bug as [image] Rhino 8.3 Error When Using Legacy GHPython for the First Time Grasshopper This used to be - probably still is - an issue in Rhino 6 and 7 on macOS, when launching a Grasshopper file from Finder, without opening Rhino first. The fi…

[image] Ehsan Iran-Nejad: Looks like it is the same bug as I don’t think so, but might be wrong. That bug appears to be the Solution exception:Object reference not set to an instance of an object error message being raised when one of the two shipped GHPython components (the upper one if I re…

I just updated to Rhino 8.5.24044.18001 and I’m afraid this issue persists. It means that Rhino 8 is a nonstarter for us/me (we’re currently evaluating when to roll it out for the entire office), as most of my internal modelling pipelines implement GHPython running in SDK mode …

Hi Anders, I’m gonna need your help to make my machine replicate this problem. Would you mind checking these for me: Disable RhinoCodePlugin in plugin manager and load Rhino. See if the ironpython components behave now. I’m trying to see if there is a conflict between the ironpythons there Wh…

Cheers @eirannejad , I’ll get back to you with these tests. But one thing I just thought to test was switching the .NET runtime from NETCore to NETFramework. This appears to be related (i.e. SDK mode seems to work when running NETFramework): [2024-02-19 09_00_02-Grasshopper - unnamed] [2024-02-19 …

Was hoping to update service release, but our IT department are unresponsive. But anywho, here’s my current system info and the requested information ( @eirannejad ): ▶ System Info [image] Ehsan Iran-Nejad: Disable RhinoCodePlugin in plugin manager and load Rhino. See if the ironpython components …

Thank you so much for the detailed tests. I think we found the problem. There are two GHPython.gha assemblies loaded and each have their own ExecutingComponent type definition. Somewhere in there IronPython component is compiling the MyComponent against one of the ExecutingComponent types but tries …

[image] Ehsan Iran-Nejad: Do you have any *.ghpy files anywhere under %%APPDATA%\Grasshopper folder? Afraid not, there are no .ghpy files on my system. No .ghuser either (I had two custom GHPython components, but removed them as well during these tests).
