You do not seem to printing out msg, you have assumed it means reinit it seems.
What does msg contain when it fails?

Learning tkinter
I am trying to learn tkinter. Several examples on the internet refer to a messagebox class (tkinter.messagebox). But: Python 3.8.3 (tags/v3.8.3:6f8c832, May 13 2020, 22:20:19) [MSC v.1925 32 bit (Intel)] on win32 Type "help", "copyright", "credits" or "license" for more information. >>> import tkinter >>> tkinter.messagebox Traceback (most recent call last): File "", line 1, in AttributeError: module 'tkinter' has no attribute 'messagebox' >>> Why is this?

Re: Help on ImportError('Error: Reinit is forbidden')
Hi Barry,
void handleError(const char* msg)
{
...
PyErr_Fetch(&pyExcType, &pyExcValue, &pyExcTraceback);
PyErr_NormalizeException(&pyExcType, &pyExcValue, &pyExcTraceback);
PyObject* str_value = PyObject_Repr(pyExcValue);
PyObject* pyExcValueStr = PyUnicode_AsEncodedString(str_value, "utf-8",
"Error ~");
const char **strErrValue* = PyBytes_AS_STRING(pyExcValueStr);
//where *strErrValue* = "ImportError('Error: Reinit is forbidden')"
...
}
What we imported is a Python file which import some pyd libraries.
Thanks

Please do not top post replies.
Ok so assume the error is correct and hunt for the code that does the
reimport.
You may need to set break points in you C code to find tnw caller.

So: > > $ sudo apt-get install python3-tk And in general, on Linux systems, you'll be better off in the long run if you use the distro's package manager to install Python packages instead of using pip. If there is no distro package, you're usually also better off using 'pip install --user' so that pip isn't messing about with directories that are normally managed by the distro's package manager. When I do have to resort to using pip in install something, I always do a --dry-run first and make a note of any dependancies that pip is going to try to install -- so I can install those using the package manager if possible. -- Grant -- https://mail.python.org/mailman/listinfo/python-list
