Hi,

   When did the change from "layers" to "layer" happen and what else has been changed?

   blob_lr -> lr_mult
   type: "Data" -> type: IMAGE_DATA

   A lot of examples floating around, am I the only one in the dark?

The latest protobuf format was adopted in PR #1694 and all the examples bundled in Caffe should follow this standard. Please send patches for any inconsistencies!

Thanks for the pointer. I am aware of this thread but it is difficult to sort out the final specification from the brain storming of 8 people. Is there a final version one can look at?

A lot of questions and answers on this forum are provided in the old format. They are very helpful to a lot of people. It would be unrealistic to have them all converted to the new form.

There's always a definitive specification: it's the proto definition at https://github.com/BVLC/caffe/blob/master/src/caffe/proto/caffe.proto

Note there's an upgrade utility for converting old prototxt too: https://github.com/BVLC/caffe/blob/master/tools/upgrade_net_proto_text.cpp

Hope that helps,

Thanks for the upgrade utility. That part is certainly helpful.

On the other hand, I can't quite connect the dots from the caffe.proto to the *.prototxt input format. Is it explained somewhere?
