Using Caffe pretrained model for FCN-Image-Segmentation

I am trying to compile the following model: http://manutdzou.github.io/2016/12/27/FCN-segmentation.html

but I got the error:

KeyError: 'fc6_my'

When I look to: solver.net.params.keys(), I get the output as: odict_keys([ ])

I don't know why it is giving no keys for the object: solver.net.params.
