Error numpy install

[GP]

I have installed numpy using the command pip install numpy from command prompt and I am getting the following error:
Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    import numpy
  File "C:\Users\GP\AppData\Local\Programs\Python\Python35\lib\site-packages\numpy\__init__.py", line 180, in <module>

    from . import multiarray
ImportError: cannot import name 'multiarray'

I have also tried to install multiarray but it says: "Could not find a program that satisfies the requirement multiarray(from versions)

Any suggestions on how to install
