I am having similar issues ...

Same error. Solved by downgrading tensorflow to 1.7.0. ` pip install 'tensorflow==1.7.0' --force-reinstall`

This feature looks important to me, too. Especially when training the forest on large datasets.

It will be nice if it could print out that how many trees have been grown v.s. how many trees are left to grow.

@jtibshirani Is there any ad hoc ways to reduce memory usage? For example, reducing the number of trees, or restricting the tree depth, or **reduce the number of sub-samples used...

@susanathey Thanks for your kind reply. It does look like that merging forest makes a lot of sense. Just to see if I understand it correctly - if my memory...

@swager Is there a parameter in the `causal_forest` function that sets the sub-sample size? Is it the `ci.group.size ` parameter that you are referring to? ``` ci.group.size The forest will...

@swager Thanks! If I reduce sample.fraction, will it cause larger standard errors (i.e. lower confidence in the estimations)?

@swager Thanks. I see that the default value for `sample.fraction` is 0.5 - is there a reason why it is set to be 0.5? If higher values of `sample.fraction` can...

@swager What value do you recommend setting the cost parameter here to? https://gist.github.com/msegar/c15af2bfc067e5319eecfd67d785fde5#file-best_tree-r-L129 I usually set it to 1. Do you think it is fine that way?
