Dear Richard,
Now I am getting confusion, really which version of cuda I have?. Because when I give these command "cudadetect" nvcc -V, and cat /usr/local/cuda/version.txt  I am getting different answers.



rb@rameshbabu:~$ cudadetect
Detecting CUDA... There is 1 device supporting CUDA:

Device 0: "GeForce GT 610"
  CUDA Driver Version:                           8.0
  CUDA Runtime Version:                          5.0
  CUDA Capability Major revision number:         2
  CUDA Capability Minor revision number:         1
  Total amount of global memory:                 2080440320 bytes
  Number of multiprocessors:                     1

  Integrated:                                    No
  Support host page-locked memory mapping:       Yes
  Compute mode:                                  Default (multiple host threads can use this device simultaneously)


rb@rameshbabu:~$
cat /usr/local/cuda/version.txt
cat: /usr/local/cuda/version.txt: No such file or directory

rb@rameshbabu:~$ nvcc -V
The program 'nvcc' is currently not installed. You can install it by typing: sudo apt install nvidia-cuda-toolkit


The first command reports that I have
CUDA Driver Version: 8.0 and CUDA Runtime Version: 5.0, but why I am not getting any report for other two commands.

Please provide a solution.

Thanks
Ramesh

You'll only be able to have one version of the CUDA driver, but you
should be able to have multiple CUDA SDKs.
