Hi John! Is this running the research environment locally? There is no similar issue in QC production

for local dev, should no longer need clr
just use:
from QuantConnect.Research import QuantBookqb = QuantBook()
Make sure you are in the jupyter notebook started by the “lean research” command:
https://www.quantconnect.com/docs/v2/lean-cli/research
I suggest changing the port because default jupyter runs on 8888 and lean research wont give any errors when it runs on 8888

I'm having the same problem. I've been away for a bit and now QuantBook is not found in the research environment. So I added the
from QuantConnect.Research Import QuantBook
line and now I am getting an error on
CLI not found.
I just started a brand new project (just to make sure it wasn't just my code) and ran the sample research code that is given in a new project that does the Bollinger bands and it is getting the QuantBook error too so it seems something has been broken. Do I need to start a different way?
Greg Kendall
So I restarted from the home page and went back into the lab and created a new project and ran the given Bollinger band research code and low and behold it worked so it looks like my problem may have to do with me running an old version of the website that was in my browsers cache … or something like that.
