Calling `python setup.py build_ext --inplace` (also `make in`) will only
recompile the files which change without recompiling everything.
However, it is true that it can lead to some error which require a clean
and recompile everything.

Is it possible to compile just _criterion.pyx and _criterion.pxd files by
using "importpyx" or any alternative way instead of compiling the whole
sklearn library every time I introduce a change?

Sorry I don't know Cython at all. _criterion.pxd is like the header file in
C++? I see that it contains class, function and variable definitions and
their description in comments.
class Criterion is an Interface, doesn't have function definitions. By
"writing your own criterion with a given loss"
I wonder whether this (together with the caveat about it being slow if
doing python) should go into the FAQ.

The ClassificationCriterion and RegressionCriterion are now exposed in the
_criterion.pxd. It will allow you to create your own criterion.
So you can write your own Criterion with a given loss by implementing the
methods which are required in the trees.
Then you can pass an instance of this criteri
Yes, but if you write it in Python, not Cython, it will be unbearably slow.
