I've installed fancyimpute on Anaconda with pip install fancyimpute through the Anaconda terminal but I use PyCharm with Anaconda as its interpreter. I couldn't find a way to use fancyimpute in PyCharm. I searched for it through Settings/Project Interpreter/Available Packages but no luck.
use
python -m pip install fancyimpute
this will take you pycharm default python interpreter and install the package in the python site package. You will be able to see this package in your project on your pycharm terminal.
