Here's my experience of installing the NVIDIA CUDA kit 9.0 on a fresh install of Ubuntu Desktop 16.04.4 LTS.

1. Install NVIDIA Graphics Driver via apt-get
Do not use the CUDA run file to install your driver. Use
apt-get instead. This way you do not need to worry about the Nouveau stuff you read about on StackOverflow.
As of 04/11/2018, the latest version of NVIDIA driver for Ubuntu 16.04.4 LTS is 384. To install the driver, excute
sudo apt-get install nvidia-384 nvidia-modprobe
, and then you will be prompted to disable Secure Boot. Select Disable.
Reboot the machine but enter BIOS to disable Secure Boot. Typically you can enter BIOS by hitting F12 rapidly as soon as the system restarts.
Afterwards, you can check the Installation with the
nvidia-smi command, which will report all your CUDA-capable devices in the system.
Common Errors and Solutions
ERROR: Unable to load the 'nvidia-drm' kernel module.
- One probable reason is that the system is boot from UEFI but Secure Boot option is turned on in the BIOS setting. Turn it off and the problem will be solved.
nvidia-smi -pm 1 can enable the persistent mode, which will save some time from loading the driver. It will have significant effect on machines with more than 4 GPUs.
nvidia-smi -e 0 can disable ECC on TESLA products, which will provide about 1/15 more video memory. Reboot is reqired for taking effect.
nvidia-smi -e 1 can be used to enable ECC again.
nvidia-smi -pl <some power value> can be used for increasing or decrasing the TDP limit of the GPU. Increasing will encourage higher GPU Boost frequency, but is somehow DANGEROUS and HARMFUL to the GPU. Decreasing will help to same some power, which is useful for machines that does not have enough power supply and will shutdown unintendedly when pull all GPU to their maximum load.
-i <GPUID> can be added after above commands to specify individual GPU.
These commands can be added to
/etc/rc.local for excuting at system boot.
2. Install CUDA 9.0
Installing CUDA from runfile is much simpler and smoother than installing the NVIDIA driver. It just involves copying files to system directories and has nothing to do with the system kernel or online compilation. Removing CUDA is simply removing the installation directory. So I personally does not recommend adding NVIDIA's repositories and install CUDA via
apt-get or other package managers as it will not reduce the complexity of installation or uninstallation but increase the risk of messing up the configurations for repositories.
The CUDA runfile installer can be downloaded from NVIDIA's websie, or using wget in case you can't find it easily on NVIDIA:
cd wget https://developer.nvidia.com/compute/cuda/9.0/Prod/local_installers/cuda_9.0.176_384.81_linux-run
What you download is a package the following three components:
- an NVIDIA driver installer, but usually of stale version;
- the actual CUDA installer;
- the CUDA samples installer;
I suggest extracting the above three components and executing 2 and 3 separately (remember we installed the driver ourselves already). To extract them, execute the runfile installer with
cd chmod +x cuda_9.0.176_384.81_linux-run ./cuda_9.0.176_384.81_linux-run --extract=$HOME
You should have unpacked three components:
NVIDIA-Linux-x86_64-384.81.run (1. NVIDIA driver that we ignore),
cuda-linux.9.0.176-22781540.run (2. CUDA 9.0 installer), and
cuda-samples.9.0.176-22781540-linux.run (3. CUDA 9.0 Samples).
Execute the second one to install the CUDA Toolkit 9.0:
You now have to accept the license by scrolling down to the bottom (hit the "d" key on your keyboard) and enter "accept". Next accept the defaults.
To verify our CUDA installation, install the sample tests by
After the installation finishes, configure the runtime library.
sudo bash -c "echo /usr/local/cuda/lib64/ > /etc/ld.so.conf.d/cuda.conf" sudo ldconfig
It is also recommended for Ubuntu users to append string
/usr/local/cuda/bin to system file
/etc/environments so that
nvcc will be included in
$PATH. This will take effect after reboot. To do that, you just have to
sudo vim /etc/environments
and then add
:/usr/local/cuda/bin (including the ":") at the end of the PATH="/blah:/blah/blah" string (inside the quotes).
reboot, let's test our installation by making and invoking our tests:
cd /usr/local/cuda-9.0/samples sudo make
It's a long process with many irrelevant warnings about deprecated architectures (
sm_20 and such ancient GPUs). After it completes, run
cd /usr/local/cuda/samples/bin/x86_64/linux/release ./deviceQuery
The result of running
deviceQuery should look something like this:
./deviceQuery Starting... CUDA Device Query (Runtime API) version (CUDART static linking) Detected 1 CUDA Capable device(s) Device 0: "GeForce GTX 1060" CUDA Driver Version / Runtime Version 9.0 / 9.0 CUDA Capability Major/Minor version number: 6.1 Total amount of global memory: 6073 MBytes (6367739904 bytes) (10) Multiprocessors, (128) CUDA Cores/MP: 1280 CUDA Cores GPU Max Clock rate: 1671 MHz (1.67 GHz) Memory Clock rate: 4004 Mhz Memory Bus Width: 192-bit L2 Cache Size: 1572864 bytes Maximum Texture Dimension Size (x,y,z) 1D=(131072), 2D=(131072, 65536), 3D=(16384, 16384, 16384) Maximum Layered 1D Texture Size, (num) layers 1D=(32768), 2048 layers Maximum Layered 2D Texture Size, (num) layers 2D=(32768, 32768), 2048 layers Total amount of constant memory: 65536 bytes Total amount of shared memory per block: 49152 bytes Total number of registers available per block: 65536 Warp size: 32 Maximum number of threads per multiprocessor: 2048 Maximum number of threads per block: 1024 Max dimension size of a thread block (x,y,z): (1024, 1024, 64) Max dimension size of a grid size (x,y,z): (2147483647, 65535, 65535) Maximum memory pitch: 2147483647 bytes Texture alignment: 512 bytes Concurrent copy and kernel execution: Yes with 2 copy engine(s) Run time limit on kernels: Yes Integrated GPU sharing Host Memory: No Support host page-locked memory mapping: Yes Alignment requirement for Surfaces: Yes Device has ECC support: Disabled Device supports Unified Addressing (UVA): Yes Supports Cooperative Kernel Launch: Yes Supports MultiDevice Co-op Kernel Launch: Yes Device PCI Domain ID / Bus ID / location ID: 0 / 1 / 0 Compute Mode: < Default (multiple host threads can use ::cudaSetDevice() with device simultaneously) > deviceQuery, CUDA Driver = CUDART, CUDA Driver Version = 9.0, CUDA Runtime Version = 9.0, NumDevs = 1 Result = PASS
Cleanup: if ./deviceQuery works, remember to
rm the 4 files (1 downloaded and 3 extracted).
Install cuDNN 7.0
The recommended way for installing cuDNN is to
Download the "cuDNN v7.0.5 Library for Linux"
tgzfile (need to register for an Nvidia account).
sudo mvthe downloaded archive to
/usr/local. This might seem silly at first, but when you unzip it next you will see that the contents end up going to various folders under
/usr/local/cudaand would be messy to move otherwise.
cd /usr/localand extract the
sudo tar -xvzf cudnn-9.0-linux-x64-v7.tgz
sudo ldconfigto update the shared library cache.
Clean up now or later by
sudo rm cudnn-9.0-linux-x64-v7.tgz
