I think we forgot to limit the number of features shown in the heatmap to the top 20? Here's an image where it's showing way more (this dataset has 4k features – [guillermo|https://www.openml.org/d/41159]).
The {{h2o.varimp_heatmap()}} has default {{top_n = 20}} but it doesn’t look like it’s working.
