AttributeError: module 'easyesn.backend' has no attribute 'ptp' #6

Thank you for publishing very useful library. This works well on CPU. But, I got an error when using on GPU (cupy).

AttributeError: module 'easyesn.backend' has no attribute 'ptp'

I think that numpy has ptp but cupy does not have it.

I provided a pull request to fix it. Cheers

Fixed by #13.

Thank you, "AttributeError: module 'easyesn.backend' has no attribute 'ptp'" is solved.

But, I run the PredictionExample, the following error occurred. I use cupy-cuda101==7.6.0.
