I'm giving the H2O datatable a try and am intrigued by the view() feature. It looks like a handy way to navigate a dataset:

The navigator is great: you can use g2000 to go to row 2000 . But the column headers are faint - almost invisible. The image above is on macos terminal. Below is iTerm: and the headers are invisible there:

or

Given my interest to make the datatable.view() an integral part of my development process - since I prefer ipython to jupyter notebooks it would be helpful to find a solution to this. Has anyone discovered maybe a terminal setting or two that would help?

Based on suggestion/comment from @GreenCloakGuy I have tried out applying different Profiles to the Terminal window. This is a working solution. In addition I learnt that pressing CMD-I allows dynamic switching of profiles in Terminal. That's useful!

This problem has been reported before (see https://github.com/h2oai/datatable/issues/1793), but it was fixed in datatable v0.9.0 released in July 2019.

One possibility why you may still see faint colors is that your terminal preferences could be misspecified. Please check your terminal preferences and make sure the "Bold Text" is set to the color that has high contrast with your terminal's background.

  • thx Pasha for checking in! Been watching progress of the `datatable` since 2017 and it's sufficiently superior to `dataframe` to make the jump. btw is `groupby` on expressions (not just columns list) in the near future? – WestCoastProjects Feb 24 '20 at 19:43
  • It's not in the near future, however, it is in the near past. Group-by-expression is available since v0.10.0. See tracking issue https://github.com/h2oai/datatable/issues/1383 – Pasha Feb 24 '20 at 20:48
  • awesome! for me that was the killer feature looking for to make a wholesale switch – WestCoastProjects Feb 24 '20 at 21:03
