Could anyone help about build CaffeOnSpak while caffe-distri failed ?

[kioipp]

Hi , I got a problem similar with others while building , but tried many ways still can't work , could anyone help me , it would be great helpful .

check your opencv version. I think the current CaffeOnSpark only supports openCV 2.5. You may have a newer version.

[JJJzheng]

chech your protobuf: protoc –version make sure protocbuf 2.5.0. A newer version may buring problem.

@834721662 I have made sure that the protoc is 2.5.0 ,still thanks for reply . @junshi15 Is that any document mentioned about the OpenCV version ? I saw many install guides but non of them calling about this , If it's true then it's useless to build CaffeOnSpark because my DL lab used OpenCV 3.0+ as default environment .

[JJJzheng]

@kioipp I have encountered this situation that my cuda is 9.0 and my OpenCV is 3.0 and they are in conflict when make build. So I changed my OpenCV to 2.14.13 and my maven 3.5.0 to 3.2.5. Hope that can help you.

[junshi15]

sorry, I think opencv 2.4 is what CaffeOnSpark supports. There are API changes between 2.4 and 3.2, hence the new openCV is not supported.
