Unless I am misremembering how warm starts are implemented (tree growers
around?)
the comment seems badly phrased. I think what it means to say is that
warm-starting repeatedly with the number of trees increasing by
increments of 1
will make the fitting be serial (you only built a single tree
Andy, BaseForest's fit method uses the same parallel loop, regardless of
warm-start. So, as you state, it's just that the example only adds a single
additional estimator at a time.

Hello,
Version 0.16.1 adds warm_start to RandomForestClassifier, but the documentation
doesn't include a note that warm_start disables parallelization. I found a
reference to this in a comment in the OOB Errors for Random Forests example
in the development documentation.
Hi Dale
Thanks for the code sample! Indeed, warm_start does not disable
parallelization, I can confirm by both running your code and checking the
source. Moreover, that example you mentioned was added on May, 2nd,
and it doesn't
look
