Caffe Master Branch Clip Layer prevents Openpose from loading model

[jpapon]

I am making a new issue for this, since OP closed #787.

Basically, Caffe Master recently added a clip layer that conflicts with a clip layer contained in the Body Pose 25 weights file. This causes a run-time failure when the model is loaded.
Reverting Caffe to BVLC/caffe@f019d0d fixed the issue for me.

I just changed from master to f019d0dfe86f49d1140961f8c7dec22130c83154 in the two relevant places:

openpose/CMakeLists.txt

Line 616 in f49e184

execute_process(COMMAND git checkout master WORKING_DIRECTORY ${CMAKE_SOURCE_DIR}/3rdparty/caffe)

and

openpose/CMakeLists.txt

Line 651 in f49e184

execute_process(COMMAND git checkout master WORKING_DIRECTORY ${CMAKE_SOURCE_DIR}/3rdparty/caffe)

It probably makes sense to switch to a specific tag or commit rather than master to avoid this type of issue in the future.

We are using our own Caffe (that is basically a version that we know that works from master Caffe), so we are effectively using a specific tag. It works on my case with no problem, maybe re-downloading it and re-compiling it?

Ah, you know, I've been using the main line Caffe, which worked until a couple of weeks ago. Your fork works fine. Apologies.

Thanks for the feed-back. Best

#949

I was finally able to replicate the error and fix it. Our latest https://github.com/CMU-Perceptual-Computing-Lab/caffe
should handle it now. Simply remove the whole OpenPose folder and re-install it completely (so the new Caffe is updated, otherwise the OpenPose Caffe would not be updated).

Let me know if it still fails.

So I got the same error: Clip Layer prevents Openpose from loading model. I am Openpose's version of caffee.

[libprotobuf ERROR google/protobuf/message_lite.cc:118] Can't parse message of type "caffe.NetParameter" because it is missing required fields: layer[0].clip_param.min, layer[0].clip_param.max

This is running the code from example1

[gineshidalgo99]

Use the latest code with the default Caffe that OpenPose provides (i.e., remove your current repo, and re-clone it again so the default Caffe of OpenPose is updated). Thanks!

Actually lddtree indicated that my executable was linking against the wrong libcaffe.so. Blergh.
