Problem installing CUDA on 18.04

[Peter De Groot]

Trying to enable a supported nvidia gpu as per the doc  here

https://github.com/ant-media/Ant-Media-Server/wiki/Enable-NVIDIA-GPU-Encoder-Support

Problem the doc talks about Ubuntu 16.04.  hence the links are not relevant ?

So I went to the Cuda download site and got

https://developer.nvidia.com/cuda-downloads

Which gave me some stuff... probably a lot more that I needed... So I tried that.

This gives me version 10.1........  which according to the antmedia site may cause problems.  In my case

a reboot told me that it could not find cuda.

The antmedia doc tells me to trying installing the compatibility stuff.

Sadly, I cannot find those packages..

can somebody point the best way to get the gpu working ?

I do not know what I did yesterday.. but I did have it working... but I reinstalled the OS and trashed it..

TIA

These packages for compatibility to version 10.0

sudo apt install cuda-cudart-10-0sudo apt install cuda-compat-10-0

At the risk of a tldr.... putting in the reply from support@antmedia

FWIW.... on the "cheaper" nvidia cards  .... apparently  nvidia-smi will not show you the processes running on the card... sigh..

That suggestion about grep nvenc did not seem to work either

Burak Kekec (Ant Media) Oct 11, 12:17 +03 You can easily check if gpu works as follows: Add an adaptive setting using AMS Management Console. (I guess you already did) Start a stream. Then run nvidia-smi. If gpu is used you will see there. Also, you can grep "nvenc". Kind Regards,

 

DE GROOT Peter [Eastern Goldfields College] Oct 11, 07:58 +03   Interesting..   The first one was already installed… the second one not..   Anyway.. restarted.   Here is the grep on all the logs files  in /usr/log/antmedia/logs   root@e4182s01sv026:/usr/local/antmedia/log# grep -i gpu * ant-media-server.log:2019-10-08 13:36:15,812 [http-nio2-0.0.0.0-5080-exec-2] WARN  io.antmedia.statistic.GPUUtils - UnsatisfiedLinkError no cuda installed no jnicuda in java.library.path ant-media-server.log:2019-10-08 13:57:50,532 [http-nio2-0.0.0.0-5080-exec-8] WARN  io.antmedia.statistic.GPUUtils - UnsatisfiedLinkError no cuda installed no jnicuda in java.library.path ant-media-server.log:2019-10-08 14:51:46,358 [http-nio2-0.0.0.0-5080-exec-4] WARN  io.antmedia.statistic.GPUUtils - UnsatisfiedLinkError no cuda installed no jnicuda in java.library.path ant-media-server.log:2019-10-09 11:12:38,956 [http-nio2-0.0.0.0-5080-exec-2] WARN  io.antmedia.statistic.GPUUtils - UnsatisfiedLinkError no cuda installed no jnicuda in java.library.path ant-media-server.log:2019-10-09 11:21:46,672 [http-nio2-0.0.0.0-5080-exec-7] WARN  io.antmedia.statistic.GPUUtils - UnsatisfiedLinkError no cuda installed no jnicuda in java.library.path ant-media-server.log:2019-10-09 12:15:38,732 [http-nio-0.0.0.0-5080-exec-6] WARN  io.antmedia.statistic.GPUUtils - UnsatisfiedLinkError no cuda installed no jnicuda in java.library.path Binary file ant-media-server.log matches     Interestingly… ALL the messages are from 2 days ago when I first tried the re-install… So I have to assume that if it finds a GPU it does NOT log a message..   is this true ?  In that case it must be working.. Would be nice if there was a log message to say that it found one.. FWIW….   Apparently that Not Supported  message in the process usage from  nvidia-smi is common for low end Nvidia cards…   Which is annoying as I would like to know how much work it is doing..   Anyway… I am re-broadcasting 5 streams ingested from ffmpeg and rtsp from cameras, and on an I7 I am using about 18% of total CPU. Impressive.   Cheers Peter

Burak Kekec (Ant Media) Oct 10, 10:28 +03 Did you install compatibility packages? sudo apt install cuda-cudart-10-0 sudo apt install cuda-compat-10-0   Kind Regards,
