[Numpy-discussion] plt.show() and plt.draw() doesnt work

[Josè Luis Mietta]

Hi experts!

I have a numpy array M. I generate a graph using NetworkX and then I want to draw this graph:

    import networkx as nx
    import matplotlib.pyplot as plt
    G=nx.graph(M)
    nx.draw(G)
    plt.draw()

Doing this, no picture appears. In addition, if I do `plt.show()` no picture appears.

Please help!

Best regards
