我自己解决了这个问题。

先设置PATH和LD_LIBRARY_PATH

first set PATH and LD_LIBRARY_PATH

$ export PATH=/usr/local/cuda-5.5/bin:$PATH
$ export LD_LIBRARY_PATH=/usr/local/cuda-5.5/lib64:$LD_LIBRARY_PATH

然后建立一个符号链接

Then build a symbolic link

sudo ln -s /usr/local/cuda-5.5/lib64/libcublas.so /usr/local/cuda-5.5/lib64/libcublas.so.3
