I am running Ubuntu 18.04 with CUDA 9.1. I have downloaded the CUDA 9.0 Driverless AI .deb installation from the H2O website's download page: https://www.h2o.ai/driverless-ai-download/

Unfortunately I am getting the following:

kevin@Ubuntu-XPS:~/Downloads$ sudo dpkg -i dai_1.1.4_amd64.deb 
[sudo] password for kevin:

Could it be any of the following problems:

  • Driverless AI is not yet supported on Ubuntu 18.04?
  • Driverless AI is not yet supported on CUDA 9.1?
  • The .deb file ends in amd64 but I have an Intel i7? (Although the Ubuntu 18.04 image file from the official downloads page also ends in amd64)

As of Driverless AI 1.2.2 the only version of Ubuntu that is tested is Ubuntu 16.04.

If you are having dpkg installation problems, you can try the (beta) “TAR SH” installation package style of the most recent version on h2o.ai/download (today that is 1.2.2).

(This additional new approach just unpacks into the current directory.)

Additionally, CUDA 9.1 is not supported (and probably never will be, since CUDA 9.2 is already out). But that’s not the cause of the error above.

  • Than you. Once I have run the script and unpacked the file, what do I do next? Can I install DAI from this directory, or do I just run it with the scripts? What do the `dai-env.sh`, `run-dai.sh` and `start-h2o.sh` scripts do? – KOB Aug 01 '18 at 06:08
  • use ./run-dai.sh. that will start the needed processes. – TomKraljevic Aug 03 '18 at 04:33
