I see. But in my case I have things like for i in xrange(0, num_experiments): estimators = # some pipeline etc...
so estimators should be "re-created" everytime. In any case, I recently changed my code and I am no longer using lists. With scalar numbers I think it is working and I see the correct number all the time and from both __init__ and fit(). I'm not sure if sklearn is supposed to support lists as parameters. But for now I'm no longer using lists .

This is what always happens, and that is the whole point of ``set_params``. After all, you are passing an object, not a class, and you could have other attributes set. It will always clone the estimator and do "set_params" on it, independent of n_jobs. ------------------------------------------------------------------------------ Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!
