Then install a bunch of third-party libraries

At this point, the Caffe installation is complete.

Configuring the Operating Environment

Caffe runtime needs to call Cuda Library, we create a new cafe.conf file under the/ETC/LD.SO.CONF.D directory, write the directory of the library we need

# sudo vi/etc/ld.so.conf.d/caffe.conf

Add Content:

/usr/local/cuda/lib64
