IronPython inspect.py

Hello!

I am trying to use open_abb (https://github.com/robotics/open_abb) in GH_Python however whenever I try to send a message to an ABB robot I recieve this error:

Runtime error (KeyNotFoundException): main

Traceback:
line 456, in getsourcefile, "C:\Program Files\Rhino 6\Plug-ins\IronPython\Lib\inspect.py"
line 1030, in getouterframes, "C:\Program Files\Rhino 6\Plug-ins\IronPython\Lib\inspect.py"
line 1052, in stack, "C:\Program Files\Rhino 6\Plug-ins\IronPython\Lib\inspect.py"
line 307, in send, "C:\Users\user\Desktop\RobArch\abb.py"
line 141, in set_tool, "C:\Users\user\Desktop\RobArch\abb.py"
line 506, in getmodule, "C:\Program Files\Rhino 6\Plug-ins\IronPython\Lib\inspect.py"

line 36, in init, "C:\Users\user\Desktop\RobArch\abb.py"
line 16, in script

My only idea is that I am not properly loading the abb.py module into IronPython.

Hi @bdn29

can you get this to work in the _EditPythonScript editor?

No, I have not been able to get it working in the Rhino Python script editor.

Can you try activating these two options in the _EditPythonScript editor Tools -> Options dialog, restart, and see if it helps?

I have a feeling that the ABB Python driver really might be a CPython module, but maybe it’s not the case.

It is a CPython module: https://github.com/robotics/open_abb/tree/fuerte-devel/abb_node/src

Yeah @nathanletwory but the .py file does not seem to use that file:

github.com

robotics/open_abb/blob/fuerte-devel/abb_node/packages/abb_communications/abb.py

'''
Michael Dawson-Haggerty

abb.py: contains classes and support functions which interact with an ABB Robot running our software stack (RAPID code module SERVER)


For functions which require targets (XYZ positions with quaternion orientation),
targets can be passed as [[XYZ], [Quats]] OR [XYZ, Quats]

'''

import socket
import json 
import time
import inspect
from threading import Thread
from collections import deque
import logging

log = logging.getLogger(__name__)

This file has been truncated. show original

but maybe I am missing something. I am really not an expert on that part.

Did you try that @bdn29 ?

Enabling Frames and Tracing did not fix the error in GH_Python.

I’m not sure if abb.py uses any of the c++ files in the git. I am able to get past the error and connect to the Robot by using GH_CPython. However, GH_CPython forces Grasshopper + Rhino to crash when I send more than 9 poses to the robot

I did happen to find gh-python-remote which allows me to connect to an external instance of python. abb.py has worked flawlessly in my native python so I think this will work!

Thanks for all of the help!

It would be great to know if you get it to work with gh-python-remote.

Thanks @bdn29!
