Name 'RandomUnderSampler' is not defined

I'm trying to use RandomUnderSampler. I have correctly installed the imblearn module. But still getting the error: "Name 'RandomUnderSampler" is not defined`. Any specific reason for this? Can someone please help 

from imblearn.under_sampling import RandomUnderSampler

#Random under-sampling and over-sampling with imbalanced-learn
def random_under_sampling(X,Y):

    rus = RandomUnderSampler(return_indices=True)
    X_rus, y_rus, id_rus = rus.fit_sample(X, Y)

    print('Removed indexes:', id_rus)

    plot_2d_space(X_rus, y_rus, 'Random under-sampling')

enter image description here

Since it seems that you are using IPython it is important that you execute first the line importing imblearn library (e.g. Ctrl-Enter):

from imblearn.under_sampling import RandomUnderSampler

After that the module should get imported and the name of the function is going to be defined.

If this does not work, could you reload the notebook and execute all the statements up until the random_under_sampling function to ensure nothing was missed?
