PYLOAD error message

[gswifort]

If an error occurs while loading a python module (PYLOAD), the following message is displayed:

Command: PYLOAD
Failed to import DEMO module: 
pyload failed: 

Can it be clarified somehow?

If not, I can probably move the PYLOAD command to python and display traceback.print_exc() there.

[CEXT-Dan]

I don't understand, I do see a traceback when a module fails to load, can you make an example?

[CEXT-Dan]

The way it is now, if there is an exception in python it shows it

PyRx/PyRxCore/PyRxApp.cpp

Lines 443 to 481 in 7fb82ac

	std::wstring PyRxApp::the_error()
	{
	PyAutoLockGIL lock;
	if (PyErr_Occurred())
	{
	PyObject* error_type = nullptr;
	PyObject* the_error = nullptr;
	PyObject* the_traceback = nullptr;
	PyErr_Fetch(&error_type, &the_error, &the_traceback);
	PyErr_NormalizeException(&error_type, &the_error, &the_traceback);
	if ((error_type != NULL))
	{
	std::string the_error_string, the_traceback_string;
	if (the_error != NULL)
	the_error_string = PyUnicode_AsUTF8(PyObject_Str(the_error));
	if (the_traceback != NULL && PyTraceBack_Check(the_traceback))
	{
	PyTracebackObject* traceRoot = (PyTracebackObject*)the_traceback;
	PyTracebackObject* pTrace = traceRoot;
	while (pTrace != NULL)
	{
	PyFrameObject* frame = pTrace->tb_frame;
	PyCodeObject* code = PyFrame_GetCode(frame);
	int lineNr = PyFrame_GetLineNumber(frame);
	const char* sCodeName = PyUnicode_AsUTF8(code->co_name);
	const char* sFileName = PyUnicode_AsUTF8(code->co_filename);
	the_traceback_string += std::format("\nAt {} ({}:{})", sCodeName, sFileName, lineNr);
	pTrace = pTrace->tb_next;
	}
	}
	std::string message(the_error_string + " ,Traceback - " + the_traceback_string);
	Py_XDECREF(error_type);
	Py_XDECREF(the_error);
	Py_XDECREF(the_traceback);
	return utf8_to_wstr(message);
	}
	}
	return std::wstring{ __FUNCTIONW__ };
	}

I would like to keep it in C++ for now

PyRx version <2.2.004.20250803> - the message is displayed
PyRx version <2.2.006.20250823> - the message is not displayed

[gswifort]

oh, if you hit cancel?

it doesn't help

[gswifort]

PyRx version <2.2.004.20250811> doesn't show either

[gswifort]

so something happened between v2.2.4 and v2.2.5, something here?

oh you mean this?
failed path do not match error #253, I could have broke something here
maybe provide a test case?

I see it now, I’m a little slow sometimes 😁

[CEXT-Dan]

I added a call back into python, which must have reset the error status PyErr_Occurred() was returning false
seems fixed

It works, thank you!

[gswifort]

BTW, I don't know what's going on with Failed to load module ...\pyrx\RxLoaderZ25.0.zrx: because everything works (this has been happening to me for some time now)

PyErr No module named 'RxLoaderZ25' ,Traceback - :

I don't get this
This looks like it comes from the python side. Nothing in PyRxZ25.0.zrx would try to load RxLoaderZ25.zrx
