Listing all layers

[TimZaman]

Is there a possibility of easily listing all layers and their settings? Maybe to a protobuf? If not, any ideas how I would go about most robustly implementing this?

[slayton58]

Look at caffe2/binaries/print_registered_core_operators.cc (and the compiled binary) - it prints out all registered operators.

[TimZaman]

Thanks, that's a great functionality. Does anything exist like that for caffe(1)?

[lukeyeager]

Is this what you're looking for? BVLC/caffe#2930

[TimZaman]

Ooph @lukeyeager, that's the closest thing so far. But it only gives me the layers names. I was just browsing for something reflecting the content of the caffe.proto.

[lukeyeager]

Ever since BVLC/caffe#1694 there hasn't been a way to enumerate the layers just by looking at caffe.proto.

[TimZaman]

Fair enough. A dirty combination of (1) listing all layers with your function and (2) regexing all variables within the parameters of caffe.proto will do the trick for now. Thanks!

[TimZaman]

For anyone interested, the parsed .proto to .json looks like this:
caffe.proto.json on pastebin
Might be quite handy for third party packages that make use of caffe. I'll return here when caffe2 has matured. Thanks all. Closing for now.

@TimZaman fwiw, you can introspect on protobufs using the https://developers.google.com/protocol-buffers/docs/reference/python/google.protobuf.descriptor-module, etc API, which might make the above file easier to generate in the future.

Nice one, didn't find that on my quest. Will come in handy.
