NSException with Tkinter on mac

Question

I use Tkinter to create a GUI window and select a file. The code I use is the following:

Tk().withdraw()
file = askopenfilenames(title='Chose transition file')

When I run this alone, both in Windows and OSX, it runs. However, I need it to be a part of a larger script which can be found in this link (lines 88-89). This larger script runs correctly in a windows OS, but when I run it in an OSX, I get the following error:

The code runs fine in OSX if I comment out the Tkinter code lines.

Could you please tell me what should I do to overcome this?

Answer 1

Follow the answer in this question

There is a known issue with TK and IDLE on OSX because:

Python's integrated development environment, IDLE, and the tkinter GUI toolkit it uses, depend on the Tk GUI toolkit which is not part of Python itself. For best results, it is important that the proper release of Tcl/Tk is installed on your machine.

For detail:

If you are using Python from a python.org 64-bit/32-bit Python installer for Mac OS X 10.6 and later, you should only use IDLE or tkinter with an updated third-party Tcl/Tk 8.5 (not 8.6), like ActiveTcl 8.5 installed.

If you are using Mac OS X 10.6, do not use IDLE or Tkinter from the Apple-supplied Python 2.6.1 in Mac OS X 10.6. If possible, install and use a newer version of Python and of Tcl/Tk.

If you are using Mac OS X 10.7 or later, the Apple-supplied Tcl/Tk 8.5 still has serious bugs that can cause application crashes. If you wish to use IDLE or Tkinter, install and use a newer version of Python and of Tcl/Tk.
