CUDA, cuDNN, OpenCV and Atlas must be already installed on your machine:
1. [CUDA](https://developer.nvidia.com/cuda-80-ga2-download-archive) must be installed. You should reboot your machine after installing CUDA.
2. [cuDNN](https://developer.nvidia.com/cudnn): Once you have downloaded it, just unzip it and copy (merge) the contents on the CUDA folder, e.g., `/usr/local/cuda-8.0/`. Note: We found OpenPose working ~10% faster with cuDNN 5.1 compared to cuDNN 6. Otherwise, check [Compiling without cuDNN](#compiling-without-cudnn).
3. OpenCV can be installed with `apt-get install libopencv-dev`. If you have compiled OpenCV 3 by your own, follow [Manual Compilation](#manual-compilation). After both Makefile.config files have been generated, edit them and uncomment the line `# OPENCV_VERSION := 3`. You might alternatively modify all `Makefile.config.UbuntuXX` files and then run the scripts in step 2.
4. In addition, OpenCV 3 does not incorporate the `opencv_contrib` module by default. Assuming you have OpenCV 3 compiled with the contrib module and you want to use it, append `opencv_contrib` at the end of the line `LIBRARIES += opencv_core opencv_highgui opencv_imgproc` in the `Makefile` file.
5. Atlas can be installed with `sudo apt-get install libatlas-base-dev`. Instead of Atlas, you can use OpenBLAS or Intel MKL by modifying the line `BLAS := atlas` in the same way as previosuly mentioned for the OpenCV version selection.
Build Caffe & the OpenPose library + download the required Caffe models for Ubuntu 14.04 or 16.04 (auto-detected for the script) and CUDA 8:
bash scripts/ubuntu_deprecated/install_caffe_and_openpose_if_cuda8.sh
Highly important: This script only works with CUDA 8 and Ubuntu 14 or 16. Otherwise, see doc/installation.md or Installation - Manual Compilation.
Alternatively to the script installation, if you want to use CUDA 7, avoid using sh scripts, change some configuration labels (e.g., OpenCV version), etc., then:
Install the Caffe prerequisites.
Compile Caffe and OpenPose by running these lines:
### Install Caffe ###
git submodule update --init --recursive --remote
cd 3rdparty/caffe/
# Select your desired Makefile file (run only one of the next 4 commands)
cp Makefile.config.Ubuntu14_cuda7.example Makefile.config # Ubuntu 14, cuda 7
cp Makefile.config.Ubuntu14_cuda8.example Makefile.config # Ubuntu 14, cuda 8
cp Makefile.config.Ubuntu16_cuda7.example Makefile.config # Ubuntu 16, cuda 7
cp Makefile.config.Ubuntu16_cuda8.example Makefile.config # Ubuntu 16, cuda 8
# Change any custom flag from the resulting Makefile.config (e.g., OpenCV 3, Atlas/OpenBLAS/MKL, etc.)
# Compile Caffe
make all -j`nproc` && make distribute -j`nproc`
### Install OpenPose ###
cd ../../models/
bash ./getModels.sh # It just downloads the Caffe trained models
cd ..
cp scripts/ubuntu/Makefile.example Makefile
# Same file cp command as the one used for Caffe
cp scripts/ubuntu_deprecated/Makefile.config.Ubuntu14_cuda7.example Makefile.config
# Change any custom flag from the resulting Makefile.config (e.g., OpenCV 3, Atlas/OpenBLAS/MKL, etc.)
make all -j`nproc`
NOTE: If you want to use your own Caffe distribution, follow the steps on Custom Caffe section and later re-compile the OpenPose library:
bash ./install_openpose_if_cuda8.sh
Note: These steps only need to be performed once. If you are interested in making changes to the OpenPose library, you can simply recompile it with:
make clean
make all -j`nproc`
Highly important: There are 2 Makefile.config.Ubuntu##.example
analogous files, one in the main folder and one in 3rdparty/caffe/, corresponding to OpenPose and Caffe configuration files respectively. Any change must be done to both files (e.g., OpenCV 3 flag, Atlab/OpenBLAS/MKL flag, etc.). E.g., for CUDA 8 and Ubuntu16: 3rdparty/caffe/Makefile.config.Ubuntu16_cuda8.example and scripts/ubuntu_deprecated/Makefile.config.Ubuntu16_cuda8.example.
If you updated some software that our library or 3rdparty use, or you simply want to reinstall it:
make clean && cd 3rdparty/caffe && make clean
You just need to remove the OpenPose folder, by default called openpose/
. E.g., rm -rf openpose/
.
.vcxproj
file and changing the necessary paths from CUDA 8 to 9.C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v8.0
. Otherwise, modify the Visual Studio project solution accordingly. Install CUDA 8.0 after Visual Studio 2015 is installed to assure that the CUDA installation will generate all necessary files for VS. If CUDA was already installed, re-install it after installing VS!C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v8.0
.Recommended installation method, it is simpler and offers more customization settings. See doc/installation.md. Note that it is a beta version, post in GitHub any issue you find.
Note: This installer will not incorporate any new features, we recommend to use the CMake installer.

We only modified some Caffe compilation flags and minor details. You can use your own Caffe distribution, these are the files we added and modified:
install_caffe.sh
; as well as Makefile.config.Ubuntu14.example
, Makefile.config.Ubuntu16.example
, Makefile.config.Ubuntu14_cuda_7.example
and Makefile.config.Ubuntu16_cuda_7.example
(extracted from Makefile.config.example
). Basically, you must enable cuDNN.Makefile.config.example
.make all && make distribute
in your Caffe version../Makefile.config.UbuntuX.example
(where X depends on your OS and CUDA version).CAFFE_DIR
) to your custom Caffe distribute
folder location in the previous OpenPose Makefile config file.The cuDNN library is not mandatory, but required for full keypoint detection accuracy. In case your graphics card is not compatible with cuDNN, you can disable it by:
USE_CUDNN
in the Makefile.config
file in 3rdparty/caffe
, and recompiling Caffe.Then, you would have to reduce the --net_resolution
flag to fit the model into the GPU memory. You can try values like 640x320
, 320x240
, 320x160
, or 160x80
to see your GPU memory capabilities. After finding the maximum approximate resolution that your GPU can handle without throwing an out-of-memory error, adjust the net_resolution
ratio to your image or video to be processed (see the --net_resolution
explanation from doc/demo_overview.md).
