ModuleNotFoundError: No module named 'msgpackrpc'

[Link-ying]

I am using jupyter_lab to install the use of the cosysairsim library which produces the error shown in the figure: no module named ‘msgpackrpc’. But I have already installed the rpc-msgpack library as prompted. At the same time, I don't want to install the previous version of the msgpack-rpc-python library to make AirSim work, as this will cause a version conflict with my tornado library, please advise me on how to resolve this issue. Thanks!

Could you solve it with this?

pip install msgpack-rpc-python
pip install cosysairsim
pip install tornado==4
