Through checking the source code, I basically understood the operation process of the whole system, and also made physical connection through the system carried by Raspberry Pie. In this process, I have a doubt that the kraken environment is set in miniforge 3, where the quart installation package is installed, and the code is:
pip3 install dash_bootstrap_components==1.1.0
pip3 install quart_compress==0.2.1
pip3 install quart==0.17.0
pip3 install dash_devices==0.1.3
However, in the code kraken_web_interface.py, no import similar to import quart can be found, but after the browser is finally connected to Kraken, the terminal displays that the quart connection is completed. Why?
Quart is a dependency of dash_devices. We fix it to a certain version as I recall that otherwise one of the other dependencies tries to download a more modern version which is incompatible with dash_devices.
