Using matploy throught pyplot when I quit my application I've the message :
Exception ignored in: <function Image.__del__ at 0x7fb34d3e4268>
Traceback (most recent call last):
File "/usr/lib/python3.7/tkinter/__init__.py", line 3504, in __del__
RuntimeError: main thread is not in main loop
Tcl_AsyncDelete: async handler deleted by the wrong thread
Abandon
I do the stuff into a separate thread because I want my primary thread to be responsive, no gui etc... I have only the default created figure and I've tryed to call plt.close() close('all') before the thread terminate.
It seems there is a static method in _backend_tk.py wich manage the mainloop, I've not followed all the code, but it seems it try to cleanup the rest at program exit.
Is there a way to make Tk and Tcl fully destroyed into my GUI thread ?
