Whole day I had been looking for a way to install cuda 10.0, but every methods I found were ended up with the message, "cuda : Depends: cuda-10-0 (>= 10.0.130) but it is not going to be installed".
I am quite sure above procedures are only way to install cuda 10.0 version that tensorflow-gpu==1.14 requires on "Ubuntu 18.04.5 LTS".
The very very important thing is that never install "nvidia-driver-***" driver by yourself.
Required nvidia drivers are installed while doing sudo apt install -y cuda=10.0.130-1

In addition, for me following commands are not necessary.

# It seems no need following:
sudo mkdir -p /usr/local/cuda-10.0/nccl/lib
sudo ln -s /usr/lib/x86_64-linux-gnu/libnccl.so.2 /usr/local/cuda/nccl/lib/
sudo ln -s /usr/lib/x86_64-linux-gnu/libcudnn.so.7 /usr/local/cuda-10.0/lib64/

Here shows my driver is running that twice faster than tensorflow CPU does.

I have a Tesla K80 (Linux) GPU and I want to use TF 1.14.
I have a dev GPU in which I have installed driver 435.21 and CUDA 10; I can see the PID's and memory spike here. However, on a different k8 pod which comes with preinstalled nvidia-driver 450, I am not able to see any processes when running nvidia-smi (CUDA 10).

I am using the same Docker image to install the CUDA,cUDNN, and tensorflow_gpu==1.14.0, which worded with driver version 435.21.

Does anyone have any idea what is going wrong?

this crashed my server..

sudo ln -s /usr/lib/x86_64-linux-gnu/libnccl.so.2 /usr/local/cuda/nccl/lib/

ln: target '/usr/local/cuda/nccl/lib/' is not a directory: No such file or directory

In what point is nvcc installed ?

You can have nvcc by install nvdia cuda toolkit: "sudo apt install nvidia-cuda-toolkit". Now you can check the directory again. good luck

While doing sudo apt install -y cuda=10.0.130-1 I ran into a error: cuda : Depends: cuda-10-0 (>= 10.0.130) but it is not going to be installed. Running sudo dpkg --force-all -i cuda-repo-ubuntu1804_10.0.130-1_amd64.deb fixed it for me. Note, though, that that will overwrite any existing versions.
