spp-net first steps

[etienne87]

Did anyone try to reproduce first steps of SPP-Net? What i would like to try is to run first half of alexnet (data -> conv5), define several levels of pyramid with custom maxpool layer in python to output blobs of different sizes, & then run second half (fc6-conv -> fc8-conv) for all the different levels in the pyramid. is there an example somewhere on how to define layers without the proto txt file?

It is possible to define network structure in python, see #2086 ( as of yet unmerged).

For python layers see here.

In case you haven't used caffe a lot please note that a SPP pooling layer was merged recently #2177 so specifying this from a prototxt file would probably be easiest way to get started.

This is a usage question and would belong on the mailing list.

BR, Max
