No module named 'pymysql'

I'm trying to use PyMySQL on Ubuntu. I've installed `pymysql` using both `pip` and `pip3` but every time I use `import pymysql`, it returns `ImportError: No module named 'pymysql'` I'm using Ubuntu 15.10 64-bit and Python 3.5. The same .py works on Windows with Python 3.5, but not on Ubuntu.
