When running tensorflow on ubuntu 16.04 libcuda.so.1 isn't being found.
This file is part of the CUDA tools which I should have installed ; maybe just no the right place?
I tried searching for the files via this command:

find / -type f -name "libcuda.so.1

And I get back a list of files (shortened list):

I'm not really sure what most of these files mean. Are these files part of the "libcuda" ? Or does this mean libcuda isn't installed.

Thank you.

After listening to what @ravery suggested:

I tried this:

ls /usr/local/cuda-8.0/doc/man/man7/libcuda.so.7 -la

which gave me an output of this:

-rw-r--r-- 1 root root 26 Jan 26  2017 /usr/local/cuda-8.0/doc/man/man7/libcuda.so.7

And if I run nvidia-smi I get back this:

So I have to link my libdua.os.7 to my graphics card driver?

What's the best way to find this driver. Thank you.

I also tried this:

ln -s /usr/local/cuda-8.0/doc/man/man7/libcuda.so.7 /usr/local/cuda/lib/libcuda.so.1

output:

failed to create symbolic link '/usr/local/cuda/lib/libcuda.so.1': No such file or directory

EDIT: After playing around for a few days. I'm still stuck.

More info:

If I browse my computer directory, I noticed that there is a CUDA-8.0 at this location:

/usr/local/

I also see a CUDA folder with an arrow on it (which I presume represents a shorcut) here in

   /usr/local

Second Update:

Running this command:

export PATH=$PATH:/usr/local/cuda-8.0/bin

Now nvcc --version returns:

vcc: NVIDIA (R) Cuda compiler driver

Copyright (c) 2005-2016 NVIDIA Corporation

Built on Tue_Jan_10_13:22:03_CST_2017

Cuda compilation tools, release 8.0, V8.0.61

However,

locate libcuda.so.1

still returns an empty screen.

There might be various issues. Not only with CUDA but with Nvidia-drivers too.

My advice : Install tensorflow-gpu with conda.

If you have installed CUDA9.0, I don't think there is much you can do. Please check tensorflow website for supported CUDA versions.

these are not files, they are directories that could not be opened due to permissions. Your file won't be there.

libcuda.so.1 is actually a link not a file. It links to your version file:for example, libcuda.so.1 links to libcuda.so.361.42.

The following commands will print the path where your link has to be located and find your version file.

echo $LD_LIBRARY_PATH #path

sudo find /usr/ -name 'libcuda.so.*' #version

If you find libcuda.so.1, then copy it into your path. If not make a link in your path that points to the version file.

I had the same problem on an NVIDIA GPU Cloud Image on a Standard_NV6 on Azure, running inside Docker. For me, the problem was that I was running

docker run -it tensorflow/tensorflow:latest-gpu-py3 bash

and I should have run it with the flag --runtime=nvidia or nvidia-docker instead of docker:

nvidia-docker run -it tensorflow/tensorflow:latest-gpu-py3 bash

docker run --runtime=nvidia -it tensorflow/tensorflow:latest-gpu-py3 bash
