Tensorflow complains that no CUDA-capable device is detected

Question

I'm trying to run some Tensorflow code, and I get what seems to be a common problem:

$ LD_LIBRARY_PATH=/usr/local/cuda-9.0/lib64 python -c "import tensorflow; tensorflow.Session()"
2019-02-06 20:36:15.903204: I tensorflow/core/platform/cpu_feature_guard.cc:141] Your CPU supports instructions that this TensorFlow binary was not compiled to use: AVX2 FMA

$

The key pieces of that error message seem to be:

[...] libcuda reported version is: 390.77.0
[...] kernel reported version is: 390.30.0
[...] kernel version 390.30.0 does not match DSO version 390.77.0 -- cannot find working devices in this configuration

How can I install compatible versions? Where is that libcuda version coming from?

Background

A few months ago, I tried installing Tensorflow with GPU support, but the versions either broke my display or wouldn't work with Tensorflow. Finally, I got it working by following a tutorial on how to install multiple versions of the CUDA libraries on the same machine. That worked at the time, but when I came back to the project after a few months, it has stopped working. I assume that some driver got upgraded during that time.

Investigation

The first thing I tried was to see what versions I have of the nvidia drivers and libcuda package.

$ dpkg --list|grep libcuda
ii  libcuda1-390                                                390.30-0ubuntu1                              amd64        NVIDIA CUDA runtime library

Looks like it's 390.30. Why does the error message say that libcuda reported 390.77?

Again, everything looks like it's 390.30. There were some packages that had version 390.77, but they were in the rc status. I guess I installed that version and later removed it, so the configuration files were left behind. I purged the configuration files with commands like this:

sudo apt-get remove --purge nvidia-kernel-common-390

Now, there are no packages at all with version 390.77.

$ dpkg --list|grep 390.77
$

I tried reinstalling CUDA, to see if it had been compiled with the wrong version.

$ sudo sh cuda_9.0.176_384.81_linux.run --silent --toolkit --toolkitpath=/usr/local/cuda-9.0 --override

That didn't make any difference.

Finally, I tried running nvidia-smi.

$ LD_LIBRARY_PATH=/usr/local/cuda-9.0/lib64 nvidia-smi
Failed to initialize NVML: Driver/library version mismatch
$

All of this is running on Ubuntu 18.04 with Python 3.6.7, and my graphics card is NVIDIA Corporation GM107M [GeForce GTX 960M] (rev a2).

I finally had the idea to look for any files with 390.77 in the name.

$ locate 390.77
/usr/lib/i386-linux-gnu/libcuda.so.390.77
/usr/lib/i386-linux-gnu/libnvcuvid.so.390.77
/usr/lib/i386-linux-gnu/libnvidia-compiler.so.390.77
/usr/lib/i386-linux-gnu/libnvidia-encode.so.390.77
/usr/lib/i386-linux-gnu/libnvidia-fatbinaryloader.so.390.77
/usr/lib/i386-linux-gnu/libnvidia-ml.so.390.77
/usr/lib/i386-linux-gnu/libnvidia-opencl.so.390.77
/usr/lib/i386-linux-gnu/libnvidia-ptxjitcompiler.so.390.77
/usr/lib/i386-linux-gnu/vdpau/libvdpau_nvidia.so.390.77
/usr/lib/x86_64-linux-gnu/libcuda.so.390.77
/usr/lib/x86_64-linux-gnu/libnvcuvid.so.390.77
/usr/lib/x86_64-linux-gnu/libnvidia-compiler.so.390.77
/usr/lib/x86_64-linux-gnu/libnvidia-encode.so.390.77
/usr/lib/x86_64-linux-gnu/libnvidia-fatbinaryloader.so.390.77
/usr/lib/x86_64-linux-gnu/libnvidia-ml.so.390.77
/usr/lib/x86_64-linux-gnu/libnvidia-opencl.so.390.77
/usr/lib/x86_64-linux-gnu/libnvidia-ptxjitcompiler.so.390.77
/usr/lib/x86_64-linux-gnu/vdpau/libvdpau_nvidia.so.390.77

So there they are! A closer look shows that I must have installed the newer version at some point.

$ ls /usr/lib/i386-linux-gnu/libcuda* -l
lrwxrwxrwx 1 root root      12 Nov  8 13:58 /usr/lib/i386-linux-gnu/libcuda.so -> libcuda.so.1
lrwxrwxrwx 1 root root      17 Nov 12 14:04 /usr/lib/i386-linux-gnu/libcuda.so.1 -> libcuda.so.390.77
-rw-r--r-- 1 root root 9179124 Jan 31  2018 /usr/lib/i386-linux-gnu/libcuda.so.390.30
-rw-r--r-- 1 root root 9179796 Jul 10  2018 /usr/lib/i386-linux-gnu/libcuda.so.390.77

Where did they come from?

$ dpkg -S /usr/lib/i386-linux-gnu/libcuda.so.390.30
libcuda1-390: /usr/lib/i386-linux-gnu/libcuda.so.390.30
$ dpkg -S /usr/lib/i386-linux-gnu/libcuda.so.390.77
dpkg-query: no path found matching pattern /usr/lib/i386-linux-gnu/libcuda.so.390.77

So the 390.77 no longer belongs to any package. Perhaps I installed the old version and had to force it to overwrite the links.

My plan is to delete the files, then reinstall the packages to set up the links to the correct version. So which packages will I need to reinstall?

$ locate 390.77|sed -e 's/390.77/390.30/'|xargs dpkg -S

Some of the files don't match anything, but the ones that do match are from these packages:

libcuda1-390
nvidia-opencl-icd-390

Crossing my fingers, I delete the version 390.77 files.

locate 390.77|sudo xargs rm

Then I reinstall the packages.

sudo apt-get install --reinstall libcuda1-390 nvidia-opencl-icd-390

Finally, it works!

nvidia-smi also works now.

I rebooted, and the video drivers continued to work. Hurrah!
