Recommended caffe version? / Incompatible protobufs

[nightrome]

Hi, could you indicate which version of caffe you have been using this with? I have just used the latest version of caffe-master, but somehow the protobufs seem to be incompatible.

Hi,

If I remember correctly, I've tested the code with this snapshot of caffe: https://github.com/BVLC/caffe/commit/b2982c7eef65a1b94db6f22fb8bb7caa986e6f29

Thanks for the quick response. With that snapshot it seems to work.

Hi, I have reinstall caffe (BVLC/caffe@b2982c7) as nightrome do, but i still got the same error, could you tell me which version of protobuf used in your project. Thanks

[nightrome]

Hi, for me it worked with libprotoc 2.6.1. At least that's what protoc --version outputs.

Thanks for your response, I have solved this problem by reinstall protobuf(pip install --user --upgrade protobuf==3.1.0.post1) . thanks again!
