G/10'+5" , all 16th R7 2700X vs. RTX 2060
2Ghash , default c's , no Syzygy
7 moves gm2600.bin not reversed

1: Lc0-.23.2_42850        18.5 / 32   ................  (+6 -1 =25)
2: Stockfish_20012810mod   7.0 / 16   0=0=============  (+0 -2 =14)
3: Komodo-13.2.5           6.5 / 16   00====0====1==0=  (+1 -4 =11)

32 games  78% draws  (white +6 -1 =25  58%)


An unusual game. Komodo's 32...Nexg3 soon gets 4 pawns for a minor piece.
After 48...Rxa3 it has 5 pawns vs. white's bishop and knight!?

Here is how I got Lc0 (cuda) on my Ubuntu 19.10

The main instructions are at https://github.com/LeelaChessZero/lc0 .

I am a total rank beginner at Linux, so take this with a big grain of salt !


Running Ubuntu 19.10, AMD Ryzen 7 2700X, RTX 2060
(recent UEFI install with official iso via Rufus to USB on Windows)
Ubuntu's 'Additional Software' recomended the propriety Nvidia driver 435, so I selected that after I first installed. 
-------------------------------------------------------
:~$ = terminal commands that I used (my username@computername not shown).
Terminal output sometimes follows, no sybols first - but most of it is not shown here.

Hint: avoid hand typing whenever possible: always cut & paste from reputable sites, not necessarily from here.

Do research on the web as much as is practical first.

{} = NOT for the terminal, only my comments for readability here.

Hint: for major installs select and copy, no matter how long, the terminal text to a text file and save; then if all seems to go well you can close and re-open a new terminal for the next major install.

-> preseeds an action to follow.

{I did this after my first try failed, mentioned below. The order did not seem critical - luckily.}
-------------------------------------------------------


__--Step 0) Set-up

:~$ sudo apt update {just to be sure, your last system update will probably be fine though}

-> 'Ubuntu Software' install latest CMake {perhaps optional, not in :Lc0-GitHub Instructions:, the page at https://github.com/LeelaChessZero/lc0 .}

-> Sign-up as a GitHub Member, you pick a name and give them your email

{For GitHub git system, also used by the building system as mentioned in :Lc0-GitHub Instructions:}
:~$ sudo apt install git 
{Long text output not shown. The instructions did not mention the output's 'Suggested packages:...' so I did not install any.}

:~$ git --version {To be sure its okay, then configure:}
git version 2.20.1
:~$ git config --global user.name "your GitHub name"
:~$ git config --global user.email "your GitHub email"

{Note: at this point I did, because it was mentioned in the install git output:}
:~$ sudo apt autoremove
{in Ubuntu it seems to me just to delete to save space -in my case the 2nd from the last kernal, the last is still there with the current; seen with 'Disk Usage Analyzer' for the disk not Home.}


__--Step 1) Optain the sourse

{As in :Lc0-GitHub Instructions: "Downloading source" the command in the grey box under "Download using git:"}
:~$ git clone -b release/0.23 --recurse-submodules https://github.com/LeelaChessZero/lc0.git

{! This results in a folder in your Home named lc0 all ready to use !
This is the source and self-running scripts to compile the lc0 executable.}


__--Step 2) Compilers

{:Lc0-GitHub Instructions: Only the top line in the grey box in the "Ubuntu 18.04" section.
Installs the compiler and things listed, long text output after not shown.}
:~$ sudo apt-get install clang-6.0 ninja-build pkg-config protobuf-compiler libprotobuf-dev meson

:~$ gcc --version {check your active version: ! Cuda 10 does not support gcc > 7 !}
gcc (Ubuntu 9.2.1-9ubuntu2) 9.2.1 20191008

~$ sudo apt-get install gcc-7 {gets the 'official' for Ubuntu 19.10, no .x}
~$ sudo apt-get install g++-7 {long text output for each}

{I found this on the web - very handy to see all the compilers installed; most everything but gcc/g++ is from the above clang... (llvm too), cuda is from my failed 1st try but okay here:}
:~$ dpkg --list | grep compiler

{Then I use here the 'alternatives' method to switch -and back after!- the default gcc/g++ version.
Another method is the 'symlink' (softlink is not the official term) at:
https://stackoverflow.com/questions/6622454/cuda-incompatible-with-my-gcc-version
but I did NOT use that, I presume g++ etc. would have to be done also though the above page just shows gcc.
Note: the alternatives method is explained at*: https://askubuntu.com/questions/923337/installing-an-older-gcc-version3-4-3-on-ubuntu-14-04-currently-4-8-installed .}

~$ sudo update-alternatives --config gcc {just to be sure there are not any yet}
update-alternatives: error: no alternatives for gcc

{The following 2 sudo update-... commands are quite long but it is necessary to 'slave' together the 7's parts and the 9's parts.}

~$ sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-9 60 --slave /usr/bin/gcc-ar gcc-ar /usr/bin/gcc-ar-9 --slave /usr/bin/gcc-nm gcc-nm /usr/bin/gcc-nm-9 --slave /usr/bin/gcc-ranlib gcc-ranlib /usr/bin/gcc-ranlib-9 --slave /usr/bin/g++ g++ /usr/bin/g++-9
update-alternatives: using /usr/bin/gcc-9 to provide /usr/bin/gcc (gcc) in auto mode
{See the alternatives link *, just above: the "60" and "40" are not required but must add up to <= 100, here 60 means no subsequent can be > 60 so 9 must be for auto mode (auto/manual applies to the switching only, uneffects users such as Cuda etc. of the alternative).} 

:~$ sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-7 40 --slave /usr/bin/gcc-ar gcc-ar /usr/bin/gcc-ar-7 --slave /usr/bin/gcc-nm gcc-nm /usr/bin/gcc-nm-7 --slave /usr/bin/gcc-ranlib gcc-ranlib /usr/bin/gcc-ranlib-7 --slave /usr/bin/g++ g++ /usr/bin/g++-7

{The following does the actual switch:}
~$ sudo update-alternatives --config gcc
There are 2 choices for the alternative gcc (providing /usr/bin/gcc).

  Selection    Path            Priority   Status
------------------------------------------------------------
* 0            /usr/bin/gcc-9   60        auto mode
  1            /usr/bin/gcc-7   40        manual mode
  2            /usr/bin/gcc-9   60        manual mode

Press <enter> to keep the current choice[*], or type selection number: 1
update-alternatives: using /usr/bin/gcc-7 to provide /usr/bin/gcc (gcc) in manual mode
{I entered 1 as the terminal showed, then the output confirmed 7 as the gcc (again 'manual' is unimportant to Cuda/ gcc users: just that the correct one is selected). "sudo update-alternatives --auto gcc" restores the highest priority, or enter its number similarily to the above.}


__--Step 4) Install Cuda

{Note: I did not install OpenCL nor OpenBLAS because I will not be using those backends.}

-> Go to the CUDA link in :Lc0-GitHub Instructions:
"Linux
Generic
    Install backend:
        If you want to use NVidia graphics cards Install CUDA https://developer.nvidia.com/  and cuDNN [** below]

-> At the Nvidia page click at the top "Downloads"
-> In the drop-down menu select "CUDA Toolkit"
-> At the CUDA Tookit page click the green box "Download Now >"
-> At the Select Target Platform page click the following green boxes:
-"Linux" -"x86-64" -"Ubuntu" -"18.04", finally -"deb (network)"

Then a short list "Installation Instructions:" which are terminal commands, appear below the boxes.
-> EXCEPT for the last one: one at a time for each "$" copy the text after it to your terminal after your "$" and enter.
You'll get various long text output and when its done go the next one.
-> LAST ONE: replace "sudo apt-get -y install cuda"
with 'sudo apt-get -y install cuda-10.0' and enter. {This changed my Nvidia display driver to 440, which was not and option before this but seems okay.}

{I took the advise at :Lc0-GitHub Instructions: "If you don't know what to do, only install cuda-10-0." and did no more with Cuda.}


__--Step 5) Install cuDNN

-> Go to the ** above link for cuDNN https://developer.nvidia.com/cudnn
-> Click the green box "Download cuDNN>"
-> At "NVIDIA Developer Program Membership Required" 'Login' or 'Join now'
-> Agree to the terms and click "Download cuDNN v7.6.5 (November 5th, 2019), for CUDA 10.0"

-> Choices appear, download each: 'cuDNN Runtime Library for Ubuntu18.04 (Deb)'
and 'cuDNN Developer Library for Ubuntu18.04 (Deb)'

-> Find them in you Downloads folder (or location) and for each:
right click, select 'Open with Software Install'. You will get an "installed" confirmation, this is all for the cuDNN's.


__--Step 6) Run the lc0 build system

At the end of the "Ubuntu 18.04" section :Lc0-GitHub Instructions: says:
"Make sure that ~/.local/bin is in your PATH environment variable." In Ubuntu 19.10 home/.profile text file already has it.
{The lc0 executable will be in lc0/build/release also, name lc0.}

-> In your terminal cd to your /home/"your username"/lc0 folder -the new folder from Step 1), if 'at home' cd lc0.
-> Yours should now say:
"your username"@"your machine name":~/lc0
-> Enter the 2nd command in the "Ubutu 18.04" section box:
:~/lc0$ CC=clang-6.0 CXX=clang++-6.0 INSTALL_PREFIX=~/.local ./build.sh

{If this fails somehow, like my 1st try with gcc-9 still active, I beleive that before re-runing you must Trash your Home lc0 folder and re-git a "fresh" one as in Step 1).
(It seems to "build" in there with many additions that would be duplicated if a 2nd time with it.)
Luckily this was all that was needed in my case.}

-> If all goes well reset your compiler to 19.10's original:
:~$ sudo update-alternatives --auto gcc 
update-alternatives: using /usr/bin/gcc-9 to provide /usr/bin/gcc (gcc) in auto mode
{It will confirm, or see Step 3) above.}

:Lc0-GitHub Instructions: says: "lc0 --help and start."
-> cd to ~/.local/bin {OR} ~/lc0/build/release
:~/.local/bin$ ./lco --help
{This runs lc0's help feature - if you see a long list of lc0 UCI settings described then your new lc0 is probably working.}

Thanks for showing how you got LC0 running on Ubuntu. This is quite the chore.

I have been waiting for a package that I can install LC0 with. So far, I've not found one. Until that becomes available, I won't be running LC0.
Parent - By MrKris (***) Date 2020-02-06 00:04
You are welcome!

(And thank you for posting that you noticed it, I would have been wondering if anyone had.. :smile: )

I am a little pessimistic about a package since its been so long already without one.
Nvidiia might have cuDNN locked to a live download by members only, though.
Also, I wonder what is wrong with a Linux executable like they have for Windows. (And Stockfish etc. pre-compiled for Linux.)

Although luckily it was not a problem in my case (RTX 2060) the Nvidia cuda-10.0 install switched my display driver up from Nvidia 435 to 440.

P.S. Snap has scidvspc. "chess" in the search bar here has a very few other chess apps: https://snapcraft.io/store
_________________________________________________________________________
(My Ubuntu 19.10 was 'fresh' so if worse came to worse I would have only had to re-install just it.)
Its a bad idea to follow amateur instructions like mine anyway.
Out of curiosity I counted 18 necessary terminal commands - the bold links are part of them (although the system here is making them 'clickable'):

:~$ sudo apt install git
:~$ git config --global user.name "your GitHub name"
:~$ git config --global user.email "your GitHub email"
:~$ git clone -b release/0.23 --recurse-submodules https://github.com/LeelaChessZero/lc0.git

:~$ sudo apt-get install gcc-7
:~$ sudo apt-get install g++-7
:~$ sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-9 60 --slave /usr/bin/gcc-ar gcc-ar /usr/bin/gcc-ar-9 --slave /usr/bin/gcc-nm gcc-nm /usr/bin/gcc-nm-9 --slave /usr/bin/gcc-ranlib gcc-ranlib /usr/bin/gcc-ranlib-9 --slave /usr/bin/g++ g++ /usr/bin/g++-9
:~$ sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-7 40 --slave /usr/bin/gcc-ar gcc-ar /usr/bin/gcc-ar-7 --slave /usr/bin/gcc-nm gcc-nm /usr/bin/gcc-nm-7 --slave /usr/bin/gcc-ranlib gcc-ranlib /usr/bin/gcc-ranlib-7 --slave /usr/bin/g++ g++ /usr/bin/g++-7
:~$ sudo update-alternatives --config gcc
{select gcc 7}

{Dowload CUDA (says 'Toolkit 10.2' the latest)
https://developer.nvidia.com/cuda-downloads
"deb (network)" last box selection, then the intructions showing there 1 at a time:}
