我正在尝试在 Google Colab 上运行 PyOpenPose 。

它需要CUDA，我就是这样做的。

!wget https://developer.nvidia.com/compute/cuda/10.0/Prod/local_installers/cuda-repo-ubuntu1804-10-0-local-10.0.130-410.48_1.0-1_amd64 -O cuda-repo-ubuntu1804-10-0-local-10.0.130-410.48_1.0-1_amd64.deb
!dpkg -i cuda-repo-ubuntu1804-10-0-local-10.0.130-410.48_1.0-1_amd64.deb
!apt-key add /var/cuda-repo-10-0-local/7fa2af80.pub
!apt-get update
!apt-get install cuda

它需要 OpenCV3，我只是使用 -

!apt-get -qq install -y libsm6 libxext6 && pip install -q -U opencv-python

为了解决一堆错误，我安装了其他几个包-

!apt-get install build-essential checkinstall pkg-config yasm
!apt-get install gfortran
!apt-get install libjpeg8-dev libjasper-dev libpng12-dev
!apt-get install libtiff5-dev
!apt-get install libavcodec-dev libavformat-dev libswscale-dev libdc1394-22-dev
!apt-get install libxine2-dev libv4l-dev
!apt-get install libgstreamer0.10-dev libgstreamer-plugins-base0.10-dev
!apt-get install qt5-default libgtk2.0-dev libtbb-dev
!apt-get install libatlas-base-dev
!apt-get install libfaac-dev libmp3lame-dev libtheora-dev
!apt-get install libvorbis-dev libxvidcore-dev
!apt-get install libopencore-amrnb-dev libopencore-amrwb-dev
!apt-get install x264 v4l-utils
!apt-get install libgoogle-glog-dev
!apt-get install libopencv-dev

然后我像这样安装了CuDNN -

!wget "http://developer.download.nvidia.com/compute/redist/cudnn/v5.1/cudnn-8.0-linux-x64-v5.1.tgz"
!tar -xvzf cudnn-8.0-linux-x64-v5.1.tgz
!cp cuda/include/cudnn.h /usr/local/cuda/include
!cp cuda/lib64/libcudnn* /usr/local/cuda/lib64
!chmod a+r /usr/local/cuda/include/cudnn.h /usr/local/cuda/lib64/libcudnn*
!dpkg -i libcudnn7_7.3.0.29-1+cuda10.0_amd64.deb
!apt-get install -f

然后我按照建议克隆了 OpenPose。改为目录。设置os.environ['OPENPOSE_ROOT'] = os.getcwd() 了一个构建目录。安装了cmake。然后尝试构建它，它有效。

!mkdir build
os.chdir("build")
!apt update
!apt install -y cmake
!cmake ..

接下来，我继续在 PyOpenPose 中创建了一个构建目录。尝试运行它，它说它需要 Boost 库。我使用这些命令安装了它 -

!apt-get install libboost-all-dev

我可以看到usr/lib/x86_64-linux-gnu（设置为os.environ['BOOST_LIBRARYDIR']）中存在的 boost 库

而 boost 位于/usr/include/boost（设置为os.environ['BOOST_ROOT']）

经过所有这些努力，我在使用!cmake ..构建目录时遇到了这个错误：

我的运行时是带有 GPU 的 Python3。我该如何解决这个问题，到目前为止一切都还好吗？

更新1： !cmake -D WITH_PYTHON3=True ..修复了。现在停留在检测 PythonLibs 上。

错误：
