Only 'extras' file exists in /usr/local/cuda-8.0

I installed CUDA 8.0 toolikit through deb file,
but there is no ‘bin’ file in /usr/local/cuda-8.0, only ‘extras’ file exists.
I followed installation guide as far as I know.
Could anybody help me out?

Env: ubuntu 16.04, gtx1080

Ubuntu 17.04 is not officially supported by any current version of CUDA, and in particular you’re going to have trouble with the C compiler. Also, CUDA 8.0.44 is not the recommended CUDA 8 version anymore.

Get your cuda installers from here:

http://www.nvidia.com/getcuda

Follow the install instructions (carefully!) in the linux install guide:

http://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html#abstract

the login loop is a problem not unique to Ubuntu 17.

If you search on ubuntu cuda login loop, you’ll find instructions for how to avoid it (including various writeups on this forum)

for example:

https://devtalk.nvidia.com/default/topic/878117/-solved-titan-x-for-cuda-7-5-login-loop-error-ubuntu-14-04-/

when you install cuda more than one time,you must use :
sudo rm -rf /usr/local/cuda*
sudo apt-get remove cuda-*
to uninstall the original cuda

same here. have you solved the problem?
