caffe使用錯誤集錦
1、caffe編譯錯誤undefined reference toTIFFIsTiled@LIBTIFF_4.0'
今天編譯caffe ,本來編譯過無數次caffe了，基本坑都能解決的。但這次惹惱我了。一直搞不定。
錯誤資訊是這樣的：
/usr/lib/x86_64-linux-gnu/libopencv_highgui.so.2.4.8: undefined reference to `TIFFIsTiled@LIBTIFF_4.0' /usr/lib/x86_64-linux-gnu/libopencv_highgui.so.2.4.8: undefined reference to `TIFFOpen@LIBTIFF_4.0' /usr/lib/x86_64-linux-gnu/libopencv_highgui.so.2.4.8: undefined reference to `TIFFReadEncodedStrip@LIBTIFF_4.0' /usr/lib/x86_64-linux-gnu/libopencv_highgui.so.2.4.8: undefined reference to `TIFFSetField@LIBTIFF_4.0' /usr/lib/x86_64-linux-gnu/libopencv_highgui.so.2.4.8: undefined reference to `TIFFWriteScanline@LIBTIFF_4.0' /usr/lib/x86_64-linux-gnu/libopencv_highgui.so.2.4.8: undefined reference to `TIFFGetField@LIBTIFF_4.0' /usr/lib/x86_64-linux-gnu/libopencv_highgui.so.2.4.8: undefined reference to `TIFFScanlineSize@LIBTIFF_4.0' /usr/lib/x86_64-linux-gnu/libopencv_highgui.so.2.4.8: undefined reference to `TIFFSetWarningHandler@LIBTIFF_4.0' /usr/lib/x86_64-linux-gnu/libopencv_highgui.so.2.4.8: undefined reference to `TIFFSetErrorHandler@LIBTIFF_4.0' /usr/lib/x86_64-linux-gnu/libopencv_highgui.so.2.4.8: undefined reference to `TIFFReadEncodedTile@LIBTIFF_4.0' /usr/lib/x86_64-linux-gnu/libopencv_highgui.so.2.4.8: undefined reference to `TIFFReadRGBATile@LIBTIFF_4.0' /usr/lib/x86_64-linux-gnu/libopencv_highgui.so.2.4.8: undefined reference to `TIFFClose@LIBTIFF_4.0' /usr/lib/x86_64-linux-gnu/libopencv_highgui.so.2.4.8: undefined reference to `TIFFRGBAImageOK@LIBTIFF_4.0' /usr/lib/x86_64-linux-gnu/libopencv_highgui.so.2.4.8: undefined reference to `TIFFReadRGBAStrip@LIBTIFF_4.0' collect2: error: ld returned 1 exit status make[2]: *** [/home/lex/catkin_ws/devel/lib/kinect2_calibration/kinect2_calibration] Error 1 make[1]: *** [iai_kinect2/kinect2_calibration/CMakeFiles/kinect2_calibration.dir/all] Error 2 make[1]: *** Waiting for unfinished jobs.... /usr/lib/x86_64-linux-gnu/libopencv_highgui.so.2.4.8: undefined reference to `TIFFIsTiled@LIBTIFF_4.0' /usr/lib/x86_64-linux-gnu/libopencv_highgui.so.2.4.8: undefined reference to `TIFFOpen@LIBTIFF_4.0' /usr/lib/x86_64-linux-gnu/libopencv_highgui.so.2.4.8: undefined reference to `TIFFReadEncodedStrip@LIBTIFF_4.0' /usr/lib/x86_64-linux-gnu/libopencv_highgui.so.2.4.8: undefined reference to `TIFFSetField@LIBTIFF_4.0' /usr/lib/x86_64-linux-gnu/libopencv_highgui.so.2.4.8: undefined reference to `TIFFWriteScanline@LIBTIFF_4.0' /usr/lib/x86_64-linux-
解決辦法是用了下面幾條命令。
cd
mkdir bak
mv /home/bxx-yll/anaconda2/lib/libtiff.so* ~/bak/
查看了一下，都是下面一些不知道什麼鬼東西。
再次編譯，他成功了，並且在anaconda2下面自動又建立了libtiff.so。
/home/bxx-yll/anaconda2/lib/libtiff.so
/usr/lib/x86_64-linux-gnu/libtiff.so
/usr/lib/x86_64-linux-gnu/libtiff.so.5
/usr/lib/x86_64-linux-gnu/libtiff.so.5.2.0
估計是衝突了。什麼鬼問題都有。既然我填坑了就把它分享給大家。編譯完成了，不知道會給其他地方造成什麼問題，索性還是挪回去。
cd
mv ~/bak/ /home/bxx-yll/anaconda2/lib/libtiff.so*

出現這樣的錯誤一般是在訓練或者測試的時候出現的（編譯階段還不會報錯），原因在於你使用的Python版本使用了Python修改了其中的網路層，所以在編譯的時候需要在Makefile.config中將 WITH_PYTHON_LAYER := 1取消註釋。然後make clean,重新執行編譯過程。
還有一種情況即使是處理了上述問題，依然是會報這個錯誤，那就要看看你的train.py或者test.py(即你執行的python檔案是否將當前的caffe匯入使用路徑)，一般的寫法是這樣的：
import sys
sys.path.insert(0, 'caffe/python')
import caffe
