Install CUDA 8.0 on google colab

hello, i have a problem.
i tried to install cuda 8.0
but instead the version that got installed is 10

while searching for solution… this is the one i found. but still cannot get cuda version 8.0

!apt update -qq;
!wget https://developer.nvidia.com/compute/cuda/8.0/Prod2/local_installers/cuda-repo-ubuntu1604-8-0-local-ga2_8.0.61-1_amd64-deb;
!dpkg -i -deb 2> /dev/null;
!apt-key add /var/cuda
/7fa2af80.pub;
!apt-get update -qq;
!apt-get install cuda gcc-5 g+±5 -y -qq;
!ln -s /usr/bin/gcc-5 /usr/local/cuda/bin/gcc;
!ln -s /usr/bin/g+±5 /usr/local/cuda/bin/g++;
!ln -s /usr/local/cuda/bin/nvcc /usr/bin/nvcc;
!apt install cuda-8.0;

is it impossible to get cuda 8.0 this days?

try this :
!wget https://developer.nvidia.com/compute/cuda/8.0/Prod2/local_installers/cuda-repo-ubuntu1604-8-0-local-ga2_8.0.61-1_amd64-deb;

!dpkg -i -deb 2> /dev/null;
!apt-key add /var/cuda
/7fa2af80.pub;

!apt-get install cuda-8.0 gcc-5 g+±5 -y -qq;
!ln -s /usr/bin/gcc-5 /usr/local/cuda/bin/gcc;
!ln -s /usr/bin/g+±5 /usr/local/cuda/bin/g++;
!ln -s /usr/local/cuda/bin/nvcc /usr/bin/nvcc;

try this–> after switching to gpu mode!!*2020
!apt update -qq;
!wget https://developer.nvidia.com/compute/cuda/8.0/Prod2/local_installers/cuda-repo-ubuntu1604-8-0-local-ga2_8.0.61-1_amd64-deb;
!dpkg -i cuda-repo-ubuntu1604-8-0-local-ga2_8.0.61-1_amd64-deb;
!apt-key add /var/cuda-repo-8-0-local-ga2/7fa2af80.pub;
!apt-get update -qq;
!apt-get install cuda gcc-5 g+±5 -y -qq;
!ln -s /usr/bin/gcc-5 /usr/local/cuda/bin/gcc;
!ln -s /usr/bin/g+±5 /usr/local/cuda/bin/g++;
!apt install cuda-8.0;

Hello, I’m using colab too. I’m trying to run a github project. At a certain point the code don"t wanna run. I’m using the GPU mode:. I tried your solution but I still have the same problem.
here what the error is
"
tensorflow/stream_executor/lib/statusor.cc:34] Attempting to fetch value instead of handling error Internal: no supported devices found for platform CUDA
Fatal Python error: Aborted"
can you solve it please?
