Hey! Just downloaded the rf.py code to contribute to my capstone project. I’m having some issues with organising and downloading the proper packages to make it work.

This is a screen shot of the problems section of my VSC.

Thanks!

Looks like you need to install NumPy. If you’re using Python 3 (recommended), enter the following command into your Terminal. If you’re using Python 2, change ‘pip3’ to ‘pip’

pip3 install numpy

return_portfolios and optimal_portfolio are custom functions made by Codecademy. They can be found in the lessons. They’re in a separate script inside the lessons. See the tabs at the top of the editor. You’ll need to copy those functions into a file in the same directory as your own script, and then import the functions as you would a normal module. I put them in a file called calc.py, so then:

from calc import return_portfolios, optimal_portfolio

As opt and blas: the Codecademy custom functions depend on a Python library called CVXOPT: Download — CVXOPT It’s not available on pip sadly. You have to download and install it separately.

I’m in a similar situation to you, wanting to use this to build my capstone project. I’m thinking of using the PyPortfolioOpt. It has some things to do with Efficient Frontiers: Efficient Frontier Optimisation — PyPortfolioOpt 1.3.1 documentation

Hey thank ya1

I ran through it again and all seems well. The issue will be importing and massaging the data to work with the functions!

opt and blas seem like very useful tools, above my level, but still interesting.
