I'm excited to experience the integration of Pycharm and LEAN Research Notebooks. I ran a strategy using the quantconnect/lean:latest image without problems. I then tried quantconnect/research:latest and Jupyter lab started ok, but running KitchenSinkQuantBookTemplate.ipynb had a problem -

from clr import AddReference

AddReference("System")

AddReference("QuantConnect.Common")

AddReference("QuantConnect.Indicators")

from System import *

from QuantConnect import *

from QuantConnect.Data.Custom import *

from QuantConnect.Data.Market import TradeBar, QuoteBar

from QuantConnect.Indicators import *



qb = QuantBook()

resulted with

---------------------------------------------------------------------------

NameError                                 Traceback (most recent call last)

<ipython-input-3-fb9797366fd4> in <module>

     17 

     18 # Create an instance

---> 19 qb = QuantBook()



NameError: name 'QuantBook' is not defined

so I tried

clr.AddReference('QuantConnect.Research')

from QuantConnect.Research import QuantBook



qb = QuantBook()

but got

---------------------------------------------------------------------------

DirectoryNotFoundException                Traceback (most recent call last)

<ipython-input-5-64eb21567b20> in <module>

      2 from QuantConnect.Research import QuantBook

      3 

----> 4 qb = QuantBook()

Could you please help with this?

OK, solved!

Copied /Lean/Data to /Lean/Launcher/bin/Debug/Notebooks

and edited config.json to point to /Lean/Launcher/bin/Debug/Notebooks/Data/

{ "data-folder": "/Lean/Launcher/bin/Debug/Notebooks/Data/",     "composer-dll-directory": "/Lean/Launcher/bin/Debug/", "algorithm-language": "Python",     "messaging-handler": "QuantConnect.Messaging.Messaging", "job-queue-handler": "QuantConnect.Queues.JobQueue",     "api-handler": "QuantConnect.Api.Api" }

You can also change this line in run_docker_notebook.sh from this:

    --mount type=bind,source=$data_dir,target=/Data,readonly \

to this to avoid doing the copying:

--mount type=bind,source=$data_dir,target=/home/Data,readonly \
