OpenCPN pypilot plugin disconnected

I am using the latest version of flask socketio now.

What do you get from the result of pip freeze?   You may need to clear the browser cache.

Here's the output

and another issue I encountered with the latest pypilot version : it is impossible to calibrate the IMU, the data rate seems to be limited to one position per second (and even when not moved, the position on the globe won't turn yellow or green, only red dots every second)
