cuda, cudnn environment configuration

wonders:

sudo gedit / etc / profile # sudo permissions required

Add at the end (note no spaces): 

Export the PATH = / usr / local / cuda- 8.0 / bin: $ the PATH 
Export LD_LIBRARY_PATH = / usr / local / cuda- 8.0 / lib64: $ LD_LIBRARY_PATH

[Optional] established cuda directory corresponds to the soft link cuda-8.0:

sudo ln -s /usr/local/cuda-8.0 /usr/local/cuda 

CUDNN:

Edit .bashrc file:

gedit ~/.bashrc

Add: Version changed their own

export PATH=/usr/local/cuda-8.0/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda-8.0/lib64:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH=/lib/x86_64-linux-gnu:$LD_LIBRARY_PATH

Updating the environment :( need to restart the terminal)

source ~/.bashrc
