Rolling Correlation calculation throwing error only in quantconnect

Back

Hey everybody, 

so I copied a code from my colaboratory into quantconnect and changed the data source accordingly. This results in a return dataframe of stocks with their respective daily returns.

Fine so far. What I want to do is calculate the respective smoothed correlations between each pair. I did that previously through the code snippet below. This time however, I received an error, which I found no documentation on.

Could someone tell me what I am doing wrong here? Because it works in my colaboratory environment.

Best regards

Hi Korbinian Gabriel,

Unfortunately, our research environment is currently using a version of numpy that does not support rolling pairwise correlation calculations. We have a scheduled update/addition of python packages coming and can get back to you after it is complete.

Best,

Derek
