When I try to import h2o I am told that the package does not exist. When I try to install it, it tells me it already exists. I have tried wiping it out of my computer and reinstalling to no avail. At this point all I can think is some environment variable.

conda packages arn't language specific, in this case conda install h2o
installs the java package. You need to do conda install h2o-py
No idea why this worked on my old computer without the -py
.

I had the same problem with conda install, but everything worked fine with:
pip install h2o

If anyone still struggling with this issue, according to docs:
H2O has tabulate>=0.75 as a dependency; however, there is no tabulate available in the default channels for Python 3.6. This is available in the conda-forge channel. As a result, Python 3.6 users must add the conda-forge channel in order to load the latest version of H2O.
Thus, you have to follow the following steps:conda config --append channels conda-forge
This, will append the conda-forge channel to your available repositories.
Then:conda install -c h2oai h2o
to install the needed packages.

For python 3.7, the h2o library is not supporting as on Feb-2019. So, I have created a new environment with 3.6 version and installed h2o using,
conda install -c h2oai h2o -n <myenvname>
