I have the following code which is giving error "TypeError: 'numpy.float64' object cannot be interpreted as an integer". The error is thrown by the statement "np.random.choice(pos_of_1, how_many_to_change)"
how_many_to_change = np.sum(Y)/2 #half of class 1 needs to be changed
pos_of_1 = np.where(Y==1) #np.where gives tuple. 1st elemetn is an np array
random_indices = np.random.choice(pos_of_1, how_many_to_change) #randomly select half of them
