From the first look does not look h2o is properly supported by conda.
Otherwise needs some documentation. i.e. not sure if it's bug ...
Please review the documentation for Installing on Anaconda Cloud. It looks like you have Python 3.6.1. Please note the tabulate dependency that is also documented. Tabulate is not available in the default channels for Python 3.6. You will have to add the condo-forge channel.
Let me know if this helps or if you’re still unable to import h2o.
We should figure out if we can get the latest version of H2O to the default anaconda channel (instead of just the h2oai channel).
