HI Rich Chiodo,
*
Thanks for taking time to respond my query
*
I actually found the issue and resolved it.
*
I had path mappings which was causing the issue i removed it - then it worked like a magic
*
But i had to call configure method before calling listen - in python script otherwise not attaching.
Python Script
debugpy.configure(subprocess=False)
debugpy.listen(5678)
debugpy.wait_for_client() # This will pause the execution until a debugger attaches
debugpy.breakpoint()
config json:
"configurations": [
{
"name": "Python Debugger: Remote Attach",
"type": "debugpy",
"request": "attach",
"connect": {
"host": "localhost",
"port": 5678
},
"justMyCode": false
}
]
My Pythonnet c# code :
PythonEngine.PythonHome = @"C:\Users\SATHISHKUMAR\AppData\Local\Programs\Python\Python39";
// Add the Python standard library to Python path
PythonEngine.PythonPath = Environment.GetEnvironmentVariable("PYTHONPATH") + ";" +
@"C:\Users\SATHISHKUMAR\AppData\Local\Programs\Python\Python39\Lib";
PythonEngine.DebugGIL = true;
PythonEngine.Initialize();
try
{
string pythonScriptPath = "D:\\debugTestPython\\script.py";
if (File.Exists(pythonScriptPath))
{
string script = File.ReadAllText(pythonScriptPath);
using (Py.GIL()) // Ensures proper handling of Python Global Interpreter Lock (GIL)
{
// Execute the Python code
PythonEngine.Exec(script);
}
}
else
{
Console.WriteLine($"File {pythonScriptPath} not found.");
}
//PythonEngine.Shutdown();
}
*
Now i can able to attach but whenever i inspect a variable the tool crashes. Any solution.?
*
Anything wrong in my configuration or script - kindly share your suggestions to improve.
Regards
Sathishkumar Jeevanantham

Can you share some example code? I can try it myself.
Reading about Pythonnet<https://pythonnet.github.io/> it sounds like it should work, but there might be something that pythonnet is doing that messes up attach.
There's also a logToFile setting you can set in VS code's launch.json. This will output a bunch of log files in your \ms-python.debugpy- folder.

VS code crashes when inspect a variable? You might try adding this setting: "logToFile": trueOr using the PYDEVD_DEBUG_FILE environment variable. It should be set to a directory that exists. |

That will generate a log file that hopefully has the crash for the debugger in it. My guess is something that pythonnet does prevents evaling different variables |

Forget to mention :
*
Whenever the debugg adapter attaches it opened a new tab in vscode with title <string> :
*
To solve this -> i added a environment variable PATHS_FROM_ECLIPSE_TO_PYTHON to map to my python script path against this <script > like this [["D:/debugTestPython/script.py","<string>"]].
*
Then it worked ,it opens the correct python script as mentioned in the env path but it opens a new tab with same script file in vscode.
Any solution to solve this problem.?
Thanks in advance
Regards
Sathishkumar

Sorry but that's by design. The pythonnet is running your python code as a string. As far as VS code and debugpy know, that's a different file. |

Maybe pythonnet can run a file instead? |
