Python Matrix.drop Examples

Example #1

    col_names = np.genfromtxt(paths.my_path + 'col_names{0}.csv'.format(month),
                              delimiter=',',
                              dtype=str)
    col_number = col_names.shape[1]
    X = Matrix(
        np.genfromtxt(paths.my_path + 'X{0}.csv'.format(month),
                      delimiter=',',
                      dtype=str), list(col_names[0, :]),
        ["%s" for i in xrange(col_names.shape[1])])
    X.drop(feature_name)
