- If you enable the `WITH_EIGEN` flag when running CMake, you must have Eigen already installed in your system. Note that [Eigen <= 3.3.6 is not supported by CUDA >=9.1](https://bitbucket.org/eigen/eigen/commits/034b6c3e101792a3cc3ccabd9bfaddcabe85bb58?at=default). In order to install it, you can perform any of the 3 following options (but only 1 of them!), while making sure that Eigen version is compatible with CUDA:
1. Do not do anything if you set the `WITH_EIGEN` flag to `BUILD`, CMake will automatically download Eigen. Alternatively, you might prefer to download it manually:
- [Eigen3](http://posefs1.perception.cs.cmu.edu/OpenPose/3rdparty/eigen_2018_05_23.zip): Unzip as `3rdparty/eigen/`.
- [Eigen3](http://posefs1.perception.cs.cmu.edu/OpenPose/3rdparty/eigen_2020_11_18.zip): Unzip as `3rdparty/eigen/`.
2. Run `sudo apt-get install libeigen3-dev` if you prefer to set `WITH_EIGEN` to `FIND`.
3. Use your own version of Eigen by setting `WITH_EIGEN` to `BUILD`, run CMake so that OpenPose downloads the zip file, and then replace the contents of `3rdparty/eigen/` by your own version.
