Hi @plajos1, use anaconda or winpython. Riskfolio-Lib was designed to work with scientific python distributions.

from riskfolio-lib.

Well it worked at least for one year with the standard Python 3.8. Just wanted you to know that something has changed with the new version.

from riskfolio-lib.

The problem is not Python 3.8, I think that the problem is that you are not using a scientific Python distribution. I recommend you to install anaconda or winpython and then use that distribution with Pycharm.

In the Conda i encountered this:

Plotting the composition of the portfolio

ax = rp.plot_pie(w=w, title='Sharpe FM Mean Variance', others=0.05, nrow=25, cmap = "tab20",
height=6, width=10, ax=None)

AttributeError Traceback (most recent call last)

Which version of Pandas are you using?

from riskfolio-lib.

1.5.3

from riskfolio-lib.

Use panda 1.3, until I update Riskfolio for a new pandas version.

from riskfolio-lib.

With that it works fine...

Hi @plajos1,

It was fixed on version 4.2.0.

Best,
Dany
