H2O Driverless AI Ubuntu DEB installation - Fail to load http://localhost:12345

344 Views Asked by At

I'm using Ubuntu v16.04.5 as a guest VMWARE in my PC. Below is the installation and status log whereby when I use the Firefox browser to open http://localhost:12345 , no page is displayed (Page not found). However, if I changed the URL to http://localhost:54321 I can see the H2o flow SW displayed in the browser.

I have started the installation using the command

$sudo dpkg -i dai_1.3.0_amd64.deb 

and

$sudo DAI_USER=ubuntu DAI_GROUP=root dpkg -i dai_1.3.0_amd64.deb 

in a separate Ubuntu v16.04.5 fresh VMWARE (guest). After that, I run the following command to start H2o driverless:

# Start Driverless AI.
sudo systemctl start dai

H2O AI driverless UBUNTU DEB installation and status log

I have also try enabling port 12345 in /etc/dai/config.toml file below and restart but the same problem still occur.

/etc/dai/config.toml

How can I get this H2o driverless working?

Note that I haven’t seen anybody do exactly this, but I don’t know of any reason why it should not work. Driverless AI runs fine in a docker container on Windows 10, which I believe is virtualbox underneath.

From the logs, it looks like you probably started the guest OS with only 2 GB of RAM. This just isn’t enough.

Give the guest at least 8 GB of RAM at the absolute rock-bottom minimum even just to run toy examples.

I don’t expect that to be a “good” experience, but chances are it will at least run.
