OpenPose圖書館 - 構建發行問題

Question

我們正在試圖安裝並運行OpenPose庫中找到一個演示在Github上： https://github.com/CMU-Perceptual-Computing-Lab/openpose/blob/master/doc/installation.md#manual-compilation

與安裝來自Caffe和所有先決條件，這樣做，但在執行安裝我們得到以下errror命令：

請幫助我得到這個蘆葦。

Answer 1

這可能是因爲libopencv_video和/或libopencv_videoio尚未添加到項目中。如果您從源代碼構建opencv，請檢查這些庫是否已經構建。

Answer 2

它看起來像你沒有檢查OpenCV3國旗同時在OpenPose，但Caffe makefiles.config文件。

例如，如果你使用手動編譯你所指出的，假設你有Ubuntu的16和CUDA 8.所以，你需要修改這兩個文件：

• https://github.com/CMU-Perceptual-Computing-Lab/openpose/blob/master/Makefile.config.Ubuntu16.example
• https://github.com/CMU-Perceptual-Computing-Lab/openpose/blob/master/3rdparty/caffe/Makefile.config.Ubuntu16.example

通過在它們中取消註釋# OPENCV_VERSION := 3。

之後，簡單地重新運行它們指定的命令：cp Makefile.config.Ubuntu16.example Makefile.config

而且make clean兩個OpenPose，但Caffe並重新構建它。
