Treeview for displaying equipment

    self.equipment_tree = ttk.Treeview(self, columns=("Name", "Practical", "Quantity"), show="headings")
    self.equipment_tree.heading("Name", text="Equipment Name")
    self.equipment_tree.heading("Practical", text="Practical Name")
    self.equipment_tree.heading("Quantity", text="Quantity")
    self.equipment_tree.pack(expand=True, fill="both")

IMPLEMENTING THIS TREEVIEW I'M HAVING THIS ERROR Python[59124:2560074] WARNING: Secure coding is not enabled for restorable state! Enable secure coding by implementing NSApplicationDelegate.applicationSupportsSecureRestorableState: and returning YES. objc[59124]: Invalid or prematurely-freed autorelease pool 0x7fe47680ae50. Set a breakpoint on objc_autoreleasePoolInvalid to debug. objc[59124]: Invalid autorelease pools are a fatal error

WHY? CAN SOMEONE HELP PLEASE
