TypeError: unsupported operand type(s) for *: 'AsyncIOLoop' and 'float'

The Python API documentation states a case where you get

TypeError: unsupported operand type(s) for *: 'AsyncIOLoop' and 'float'

This error happens if you install Jupyter, which somehow breaks the msgpackrpc library. Create a new python environment which the minimal required packages.

apparently this is caused by updating tornado package to a higher version.
it is probably better to state the required tornado package version to assure a working API.

All the above is correct. The quick fix to me was

pip uninstall airsim
pip install airsim
