5.[Run OpenPose](#run-openpose)
### Prerequisites (Ubuntu Only)
OpenCV must be already installed on your machine. It can be installed with `apt-get install libopencv-dev`. You can also use your own compiled OpenCV version.
### Caffe Prerequisites (Ubuntu Only)
By default, OpenPose uses Caffe under the hood. If you have not used Caffe previously, install its dependencies by running:
```bash
bash ./ubuntu/install_cmake.sh
```
### Prerequisites
1. Download and install CMake GUI.
- Ubuntu: run the command `sudo apt-get install cmake-qt-gui`. Note: If you prefer to use CMake through the command line, see [Cmake Command Line Build](#cmake-command-line-build-ubuntu-only).
- Windows: download and install the latest CMake win64-x64 msi installer from the [CMake website](https://cmake.org/download/), called `cmake-X.X.X-win64-x64.msi`.
- Ubuntu: Run `ubuntu/install_cuda.sh` or alternatively download and install it from their website.
- Windows: 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 CUDA after installing VS!
- Ubuntu: Run `ubuntu/install_cudnn.sh` or alternatively download and install it from their website.
- Windows (and Ubuntu if manual installation): In order to manually install it, just unzip it and copy (merge) the contents on the CUDA folder, usually `/usr/local/cuda/` in Ubuntu and `C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v8.0` in Windows.
3. (Ubuntu):
- Caffe prerequisites: By default, OpenPose uses Caffe under the hood. If you have not used Caffe previously, install its dependencies by running `bash ./ubuntu/install_cmake.sh`.
- OpenCV must be already installed on your machine. It can be installed with `apt-get install libopencv-dev`. You can also use your own compiled OpenCV version.
4. (Windows): **Microsoft Visual Studio (VS) 2015 Enterprise Update 3**.
- If **Visual Studio 2017 Community** is desired, we do not officially support it, but it might be compiled by firstly [enabling CUDA 8.0 in VS2017](https://stackoverflow.com/questions/43745099/using-cuda-with-visual-studio-2017?answertab=active#tab-top) or use **VS2017 with CUDA 9** by checking the `.vcxproj` file and changing the necessary paths from CUDA 8 to 9.
- VS 2015 Enterprise Update 1 will give some compiler errors and VS 2015 Community has not been tested.
### OpenPose Configuration
1. Download and install CMake GUI.
- Ubuntu: runn the command `sudo apt-get install cmake-qt-gui`. Note: If you prefer to use CMake through the command line, see [Cmake Command Line Build](#cmake-command-line-build-ubuntu-only).
- Windows: download and install the latest CMake win64-x64 msi installer from the [CMake website](https://cmake.org/download/), called `cmake-X.X.X-win64-x64.msi`.
2. Open CMake GUI and select the OpenPose directory as project source directory, and a non-existing or empty sub-directory (e.g., `build`) where the Makefile files (Ubuntu) or Visual Studio solution (Windows) will be generated. If `build` does not exist, it will ask you whether to create it. Press `Yes`.

If `build` does not exist, it will ask you whether to create it. Press `Yes`.
3. Press the `Configure` button, keep the generator in `Unix Makefile` (Ubuntu) or set it to `Visual Studio 14 2015 Win64` (Windows), and press `Finish`.
