Question about classifier training

[gmk11]

@Gengzigang please, in your paper in the training process of the classifier you said you fixed the backbone for save computation cost thus only the classification head is updated.
My problem is that i changed the backbone and i have the good computation power and i want to update the backbone during the classifier training. I explore your code but didn't find where you specified that in order to change it. Could you please give me hints ?
