Bug in Debugger?
Ueli Hofstetter
posted

I cloned the sample fundamentals algorithm (by the way the algorithm breaks at the end... which is a little does not put the best light on the documentation) and started debugging the update_universe function... something seems to be very strange. In the debugger, I can clearly see that the dataframe is loaded. However, when I try to access the actual sids I get an error message I cannot make any sense of....

Can someone explain this behaviour?

Hi Ueli,

I think this is related to our pandas upgrade. I'll submit it as a bug.

Thanks,
Josh
