Rhino Crash Loading Grasshopper

The gremlins have got me now - Rhino crashes when I try launching Grasshopper - several tries including reboot.
Not sure if it’s connected, but for some time I’ve had error messages when it gets to “GH Python” load…I’ve included some screen shots.

These error messages have never affected the running of Grasshopper.
Help!

Ugh - please send in that crash report, it will help us find the problem. Do you have an installation of Python other than the one Rhino brings?

-Pascal

That’s good at least we see the same thing.
I just sent a mail about Rhino crash - I’ve fixed it by Rena long the disabled plugins we tried. But I’d really appreciate your opinion on these error messages I’m getting on GH python load on GH launch.

This is most likely not GhPython, but another installed GHA that is acting up (the arduino message box seems like an awful good hint.) I would recommend trying the GrasshopperLoadOneByOne command to try and figure out which GHA is acting up.

I sent the report, of course no file included as I was just opening things up.

As for other Python installation, I don’t think so, I don’t use Python, although who knows what comes onboard with plugins…!!!

Thanks Steve didn’t know that nice sounding command! Will try.

It appears it was the GH Python Gha.
Do I just delete from the components folder?

And can I reinstall in some way?


No, don’t delete GhPython. I highly doubt this is the real source of the problem. There is another component that is interfering. Can you show me your list of installed GHAs?

If you run EditPythonScript in Rhino, do you get the python editing dialog? That’s a way to see if python is working on your Rhino

I get this window …

Here’s the list of GHA’s…

Woah, that’s a big list. @DavidRutten do you have a recommended process for using GrasshopperLoadOneByOne to resolve this issue?

if you type GrasshopperDeveloperSettings a window will pop up
there you can click on the eye icon to see all the folders on your PC from which Grasshopper is looking for plugins

I had a lot of mess in there, my “Download” folder was also in the list somehow, I had several plugins loaded which I didn’t really want to load

you can’t touch any directory which is greyed out, but if it happens you have added any on your own, you can remove them

also, you can explore the ocntent of those folders, yuou never know…
you can ignore all the folders that are under McNeel\Rhinoceros\packages… because probably you did not copy/paste anything there, same for Rhino7\plugins\Grasshopper\Components

about the “could not find arduino.exe” error in particular, it comes from Firefly plugin
just create an empty text file somewhere in a folder on your HD and rename it to arduino.exe
next time you launch GH and asks for arduino.exe, point to that file and the error will disappear

Hi Steve, Pascal,

Do you have any news on these subjets?
Also, I’ve noticed a change in the pdf export - the scale of the image of the exported object, compared to “sheet size” seems to have changed considerably - it’s much smaller now, so to “fill” the sheet, I have to zoom in so the object is bigger then th rhino viewport.

Have you done any changes? I think I did a software update last week, but I can’t be sure if it’s related.

Thanks,
Mark

I don’t understand this comment. I have been working on pdf export recently. Do you have a sample to illustrate this issue?
