Running sense hat on pi 3 using python
As soon as python executes import sense_hat the processor speed monitor on the desktop jumps from 2-3% to 75% and stays there until python is exited (when it drops back to 2-3%. This occurs from the command line as well as in a program.
In some instances the temperature warning indicator comes on as well and the pi feels very hot.
It appears importing the module is activating a background process even though no deliberate python program is running.
