单独用GPU编译darknet源码时出现如下错误：
解决方法：修改Makefile
NVCC = /usr/local/cuda-9.0/bin/nvcc
重新编译，错误解决
make
测试一下GPU版本的yolov3
./darknet detect cfg/yolov3.cfg yolov3.weights data/dog.jpg
出现如下错误：
./darknet: error while loading shared libraries: libcudart.so.9.0: cannot open shared object file: No such file or directory
解决方法：
sudo cp /usr/local/cuda-9.0/lib64/libcudart.so.9.0 /usr/local/lib/libcudart.so.9.0 && sudo ldconfig sudo cp /usr/local/cuda-9.0/lib64/libcublas.so.9.0 /usr/local/lib/libcublas.so.9.0 && sudo ldconfig sudo cp /usr/local/cuda-9.0/lib64/libcurand.so.9.0 /usr/local/lib/libcurand.so.9.0 && sudo ldconfig
若出现
./darknet: error while loading shared libraries: libcudnn.so.7: cannot open shared object file: No such file or directory
则
sudo cp /usr/local/cuda/lib64/libcudnn.so.7 /usr/local/lib/libcudnn.so.7sudo ldconfig
若出现
CUDA Error: unknown errordarknet: ./src/cuda.c:36: check_error: Assertion `0' failed.Aborted (core dumped)
加上sudo
若出现：
5 CUDA Error: out of memorydarknet: ./src/cuda.c:36: check_error: Assertion `0' failed.Aborted (core dumped)
