I'm trying to plot a seaborn clustermap (it doesn't work with the heatmap too) with the following, no NaNs admitted:

    import numpy as np
    import pandas as pd
    import seaborn as sns
    import matplotlib.pyplot as plt

    def plotClusterMap():
        a = pd.DataFrame(np.matrix('1 2; 3 4'))
        print a
        fig = plt.figure()
        sns.clustermap(a)
        plt.show()

a is well formed:

   0  1
0  1  2
1  3  4

Console output:

Python 3.4.2 and numpy 1.9.2 don't solve the error :(

Yeah as far as I understand this is a known issue in the matplotlib MacOSX backend.
