====Hardware check====The first build of this box was done with an installation of CUDA 10.1, which automatically installed version 418.67 of the NVIDIA driver. We then installed CUDA 10.0 under conda to support Tensorflow 1.13. All went mostly well, and the history of this page contains the instructions. However, at some point, likely because of an OS update, the video driver(s) stopped working. This page now describes the second build (as if it were a build from scratch). [[Addressing Ubuntu NVIDIA Issues]] provides additional information.

This looks good. The second card Check the hardware is the Titan RTX (see httpsbeing seen and what driver is being used with://devicehunt.com/view/type/pci/vendor/10DE/device/1E02). lspci -vk
You could install the driver directly now using, say, apt install nvidia-430. But don't! ====CUDA==== Get CUDA 10.1 and have it install its preferred driver (418.67): *The installation instructions are here: https://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html*You can down load CUDA from here: https://developer.nvidia.com/cuda-downloads?target_os=Linux&target_arch=x86_64&target_distro=Ubuntu&target_version=1804&target_type=runfilelocal Essentially, first install build-essential, which gets you gcc. Then blacklist the nouveau driver (see https://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html#runfile-nouveau) and reboot (to a text terminal, if you have deviated from these instructions and already installed X Windows) so that it isn't loaded.

=========== Install the CUDA 10.0 Toolkit? = Summary = =========== (y)es/(n)o/(q)uit: y
Driver: Installed Enter Toolkit Location Toolkit: Installed in [ default is /usr/local/cuda-10.1/ Samples0 ]: Installed in /home/ed/, but missing recommended libraries
Please make sure that - PATH includes Do you want to install a symbolic link at /usr/local/cuda-10.1/bin? - LD_LIBRARY_PATH includes /usr/local/cuda-10.1/lib64, or, add /usr/local/cuda-10.1/lib64 to (y)es/etc(n)o/ld.so.conf and run ldconfig as root(q)uit: y
To uninstall Install the CUDA Toolkit, run cuda-uninstaller in /usr/local/cuda-10.10 Samples? (y)es/bin To uninstall the NVIDIA Driver, run nvidia-uninstall(n)o/(q)uit: y
Fix Now fix the paths. To do this for a single user do: export PATH=/usr/local/cuda-10.10/bin:/usr/local/cuda-10.1/NsightCompute-2019.10${PATH:+:${PATH}} export LD_LIBRARY_PATH=/usr/local/cuda-10.10/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
Start But it is better to fix it for everyone by editing your environment file: vi /etc/environment PATH="/usr/local/cuda-10.0/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games" LD_LIBRARY_PATH="/usr/local/cuda-10.0/lib64" With version cuda 10.0, you don't need to edit rc.local to start the persistence daemon:
This should be run at bootInstead, so: vi /etc/rc.local #!/bin/sh -e /usr/bin/nvidia-persistenced --verbose exit 0 chmod +x /etc/rcruns as a service.local Verify the driver: cat /proc/driver/nvidia/version
Change into the sample directory and run the tests: cd /usr/local/cuda-10.10/samples/bin/x86_64/linux/release
And yes, it's a thing of beautyEverything should be good at this point! ===X Windows=== Now install the X window system. The easiest way is: tasksel And choose your favorite. We used Ubuntu Desktop. And reboot again to make sure that everything is working nicely.
And this doesn't work. It turns out that tensorflow 1.13.1 doesn't work with CUDA 10.1! But there is a work around, which is to install cuda10 in conda only (see https://github.com/tensorflow/tensorflow/issues/26182). We are also going to leave the installation of CUDA 10.1 because tensorflow will catch up at some point.
Still as researcher (and in the venv):
conda install cudatoolkit
conda install cudnn
conda install tensorflow-gpu
export LD_LIBRARY_PATH=/home/researcher/anaconda3/lib/${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
python -c "import tensorflow as tf; tf.enable_eager_execution(); print(tf.reduce_sum(tf.random_normal([1000, 1000])))"
AND IT WORKS!
After logging into First, install the box sometime later, it seems that VNC client remotely. We use the video drivers are no longer loading, presumably as a consequence of some update or somethingstandalone exe from TigerVNC.
===Testing===Now install TightVNC, following the instructions: https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-vnc-on-ubuntu-18-04

lspci -vk shows Kernel modulesInstrucions on how to set up an IP tunnel using PuTTY: https: nvidiafb, nouveau and no Kernel driver in use//helpdeskgeek.com/how-to/tunnel-vnc-over-ssh/
It looks like nouveau is still blacklisted in /etc/modprobe.d/blacklist-nouveau.conf and /usr/bin/nvidia-persistenced --verbose is still being called in /etc/rc.local. ubuntu-drivers devicesreturns exactly what it did before we installed CUDA 10.1 too...====Connection Issues====

FinallyThere is clearly an issue with Ubuntu 18.04 and XRDP.

This page details the build of our [[DIGITS DevBox]]. There's also a page giving information on [[Using the DevBox]]. nVIDIA, famous for their incredibly poor supply-chain and inventory management, have been saying [https://developer.nvidia.com/devbo "Please note that we are sold out of our inventory of the DIGITS DevBox, and no new systems are being built"] since shortly after the [https://en.wikipedia.org/wiki/GeForce_10_series Titax X] was the latest and greatest thing (i.e., somewhere around 2016). But it's pretty straight forward to update [https://www.azken.com/download/DIGITS_DEVBOX_DESIGN_GUIDE.pdf their spec].
==Introduction==
===Specification===
<onlyinclude>[[File:Top1000.jpg|right|300px]] Our [[DIGITS DevBox]], affectionately named "Bastard"after Lois McMaster Bujold's fifth God, has a XEON e5-2620v3 processor, 256GB of DDR4 RAM, two GPUs - one Titan RTX and one Titan Xp - with room for two more, a 500GB SSD hard drive (mounting /), and an 8TB RAID5 array bcached with a 512GB m.2 drive (mounting the /bulk share, which is available over samba). It runs Ubuntu 18.04, CUDA 10.1 (and CUDA 10 under conda)0, cuDNN 7.56.1, Anaconda3-2019.03, python 3.7, tensorflow 1.13, digits 6, and other useful machine learning tools/libraries.</onlyinclude>
===Documentation===
Notes:
*We will do RAID 5 array in software, rather using X99 through the BIOS
What's really crucial is that all the hardware is visible and that we are NOT using UEFI. With UEFI, there is an issue with the drivers not being properly signed under secure boot.
==Software==
Give the box a reboot!
===X Windows===
If you install the video driver before installing Xwindows, you will need to manually edit the Xwindows config files. So, now install the X window system. The easiest way is:
tasksel
And choose your favorite. We used Ubuntu Desktop.
And reboot again to make sure that everything is working nicely.
===Video Drivers===
Currently we are using the nouveau driver for the Xp, and have no driver loaded for the RTX.
driver : xserver-xorg-video-nouveau - distro free builtin
apt-get install build-essential
gcc --version
vi /etc/modprobe.d/blacklist-nouveau.conf
blacklist nouveau
update-initramfs -u
shutdown -r now
Reboot to a text terminal
lspci -vk
Shows no kernel driver in use!
Install the driver! apt install nvidia-driver-430 ====CUDA==== Get CUDA 10.0, rather than 10.1. Although 10.1 is the latest version at the time of writing, it won't work with Tensorflow 1.13, so you'll just end up installing 10.0 under conda anyway. *The installation instructions are here: https://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html*You can down load CUDA 10.0 from here: https://developer.nvidia.com/cuda-10.0-download-archive?target_os=Linux&target_arch=x86_64&target_distro=Ubuntu&target_version=1804&target_type=runfilelocalEssentially, first install build-essential, which gets you gcc.

====Test the installation====
Make the samples in:... cd /usr/local/cuda-10.10/samples
make
And change into the sample directory and run the tests:
./deviceQuery
./bandwidthTest
===Bcache===
This section follows https://developer.nvidia.com/rdp/digits-download. Install Docker CE first, following https://docs.docker.com/install/linux/docker-ce/ubuntu/
Then follow https://github.com/NVIDIA/nvidia-docker#quick-start to install docker2, but change the last command to use cuda 10.10
...
sudo apt-get install -y nvidia-docker2
sudo pkill -SIGHUP dockerd
# Test nvidia-smi with the latest official CUDA image
docker run --runtime=nvidia --rm nvidia/cuda:10.10-base nvidia-smi
Then pull DIGITS using docker (https://hub.docker.com/r/nvidia/digits/):
*https://developer.nvidia.com/digits
Note: you can kill docker containers with
docker system prune
====cuDNN====
First, make an installs directory in bulk and copy the installation files over from the RDP (E:\installs\DIGITS DevBox). Then:
cd /bulk/install/
dpkg -i libcudnn7_7.56.1.1034-1+cuda10.1_amd640_amd64.deb dpkg -i libcudnn7-dev_7.56.1.1034-1+cuda10.1_amd640_amd64.deb dpkg -i libcudnn7-doc_7.56.1.1034-1+cuda10.1_amd640_amd64.deb
And test it:
pip install --upgrade tensorflow-gpu
python -c "import tensorflow as tf; tf.enable_eager_execution(); print(tf.reduce_sum(tf.random_normal([1000, 1000])))"
Note: to deactivate the virtual environment:
deactivate
Note that adding the anaconda path to /etc/environment makes the virtual environment redundant.
