Bug summary
Using matplotlib backend for a navigation toolbar in tkinter withgrid package manager gives the error:
_tkinter.TclError: cannot use geometry manager pack inside .!frame which already has slaves managed by gridOne should be able to use either package managerspack orgrid ideally.
Code for reproduction
importtkinterimporttkinterastkfrommpl_toolkits.mplot3dimportAxes3Dfrommpl_toolkits.mplot3dimportproj3dfrommatplotlib.backends.backend_tkaggimport (FigureCanvasTkAgg,NavigationToolbar2Tk)window=tkinter.Tk()window.wm_title("MRI in Tk")frame=ttk.Frame(window)frame.grid(row=0,column=0,sticky="nsew")fig=Figure(figsize=(8,8))pc_label=FigureCanvasTkAgg(fig,master=frame)pc_label.get_tk_widget().grid(row=0,column=1)pc_toolbar_label=NavigationToolbar2Tk(pc_label,frame)pc_toolbar_label.grid(row=0,column=1,sticky="s")

Additional information
This script uses amatplotlib backend fortkinter for displaying the navigation toolbar which natively implements
the package managerpack() fortkinter. Since we usegrid() package manager, this creates a conflict and hence
you need to change theLine: 657 in[PYTHON-DIR]/site-packages/matplotlib/backends/_backend_tk.py.
One should be able to use either package managers ideally.
