npyscreen doesn't seem to have installed properly using PIP. How do I get it installed properly?

Question

I'm trying to install npyscreen to my Python 3.6.3 installation. I used PIP and it seemed to work. However when I run a program with import npyscreen I get this error:

Traceback (most recent call last):
  File "E:\Python\test.py", line 1, in <module>
    import npyscreen
  File "E:\Python\npyscreen.py", line 5, in <module>
    class TestApp(npyscreen.NPSApp):
AttributeError: module 'npyscreen' has no attribute 'NPSApp'

I'm really inexperienced and totally don't understand how PIP works, where it puts things and how I go about setting up paths etc. Can anyone help this beginner get going?
