How can I train RstarCNN with ZF pretrained model ?

[samouha]

Hi,
Because I couldn't train RstarCNN with VGG16 model (since I have a GPU sufficiency problem: I use GeForce GT630 ), I'm trying doing the train phase with ZF model (which seems need less GPU memory). But, I still have some problem in changing the parameters of the layers in the "ZF.caffemodel" !!
Is there any one who has tried this before? can any one help me please ;;;
