This is a bug in Spring Integration; I have opened a JIRA Issue. scale luminance data to [0, 1]. It computes and draws the histogram of x. Parameters. The matplotlib.pyplot.hist() function plots a histogram. log_scale bool or number, or pair of bools or numbers Set a log scale on the data axis (or axes, with bivariate data) with the given base (default 10), and evaluate the KDE in log space. That means that the features selected in training will be selected from the test data (the only thing that makes sense here). The text output of the generated bins looks OK to me: x_space: [ 0. The bi-dimensional histogram of samples x and y. membership test (s in data). It would be quicker to use boolean indexing: In [6]: A[X.astype(bool).any(axis=0)] Out[6]: array([[3, 4, 5]]) X.astype(bool) turns 0 into False and any non-zero value into True: In [9]: X.astype(bool).any(axis=0) Out[9]: array([False, True, False], dtype=bool) the call to .any(axis=0) returns True if any value in... if you only need to do this for a handful of points, you could do something like this.
