NVIDIA-SMI couldn't find libnvidia-ml.so library
I have the following Nvidia graphics card in my laptop
ant@Anthill ~> lspci -k | grep -EA2 'VGA|3D'
00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller (rev 06)
Subsystem: Lenovo 4th Gen Core Processor Integrated Graphics Controller
Kernel driver in use: i915
--
07:00.0 3D controller: NVIDIA Corporation GK208M [GeForce GT 740M] (rev a1)
Subsystem: Lenovo GK208M [GeForce GT 740M]
Kernel modules: nvidiafb, nouveau
I have installed drivers the following way
sudo apt-add-repository ppa:graphics-drivers/ppa
sudo apt-get install nvidia-370 nvidia-prime
And cuda toolkit by downloading cuda-7.5 binary from nvidia official site
sudo ./NVidia-cuda-7.5.run
All these installations were done after shifting to tty and stopping XOrg
sudo service lightdm stop
Now after restarting
ant@Anthill ~> nvidia-smi
NVIDIA-SMI couldn't find libnvidia-ml.so library in your system. Please make sure that the NVIDIA Display Driver is properly installed and present in your system.
Please also try adding directory that contains libnvidia-ml.so to your system PATH.
libnvidia-ml.so is present here
ant@Anthill ~> ls /usr/lib/nvidia-370

I tried adding this dir to the PATH and LD_LIBRARY_PATH also. Both did not work.
Also,
ls /dev | grep nvidia
Yields nothing. That is no devices are present with /dev/nivida*
Any suggestion to get this working?
Where does nvidia-smi try to find the libnvidia-ml.so?
Solution 1:
LD_PRELOAD=/usr/lib/nvidia-367/libnvidia-ml.so nvidia-smi
Solution 2:
I encountered this problem after some nvidia-docker containers crashed. libnvidia-ml.so presented at /usr/lib/nvidia-<version>, but nvidia-smi kept complaining.
I fixed the problem by sudo ldconfig.real
Solution 3:
my error was solved by doing this way
This led me to finding another solution by looking into /etc/nvidia-container-runtime/config.toml file where the ldconfig is by default set to "@/sbin/ldconfig". This for some reason seems to not be working and also produces the error above:
root@banshee:/var/log# docker run --rm --gpus=all nvidia/cuda:11.4-base nvidia-smi

Changing the ldconfig path to "/sbin/ldconfig" (instead of "@/sbin/ldconfig") does indeed fix the problem:
root@banshee:/var/log# docker run --rm --gpus=all nvidia/cuda:11.4-base nvidia-smi
