comment Generating syntatic label data vector
No, I have the correct label vector Y with 100% accuracy. For testing some stuffs, I want to generate a vector with specific accuracy using the vector Y as a reference. For example I want y_1 with 70% accuracy, using Y as reference to generate it.

matplotlib.image.imsave(filename, X_gadf[0]) for example save a png file with all colors wrong. cv2.imread(X_gadf[0]) says TypeError: expected string or Unicode object, numpy.ndarray found.

comment Get grouped informations from an array with Pandas
Yes, But afer 01/01/2015 doesn't take 01/02/2015 but 01/01/2016! This is numerical sort, not date sort! I want to perform a date sorting
