About the data type of label in regression tutorial 2

[BldgICT]

Hi, I have a simple question.

In regression tutorial 2, should label of the data always be an integer? An error occurs if the data type of label is not integer.

However, in regression tasks, the data type of labels is often not integer. For example, if the label is power consumption, it could be 10.5 or 10.6.
