Hi I am relatively new to Python so forgive me if I have missed an
elephant in the room so to speak.
My code has worked for the whole day, but this afternoon I have begun receiving the error
Traceback (most recent call last): File "C:\Documents and Settings\King Alex\My Documents\Summer Project\Python files\graphs.py", line 7, in <module> plt.show() File "D:\Python254\Lib\site-packages\matplotlib\backends\backend_tkagg.py", line 79, in show Tk.mainloop() File "D:\Python254\lib\lib-tk\Tkinter.py", line 328, in mainloop _default_root.tk.mainloop(n) AttributeError: 'NoneType' object has no attribute 'tk'
whenever I try to call
To use a simple example this occurs when I run
import networkx as nx import matplotlib.pyplot as plt G = nx.Graph() G.add_node(1) plt.show()
Help solving this is very appreciated as it occured without me making a change to my code. During running I was receiving errors from visual c++ about the program terminating unusually.
I am using python 2.5.4 with NumPy, DimPy, Matplotlib and NetworkX. Let me know if any other information would be helpful.
