scikit-learn fit function classification

I am using the fit function for classification training in scikit-learn. For example, while using random forests, one typically uses the following type of code:

import sklearn
from sklearn.ensemble import RandomForestClassifier as RF
forest=RF(n_estimators=10)
forest=forest.fit(TrainingX,Trainingy)

Unfortunately, I get the following error when using Python 3:

C:\Anaconda3\lib\site-packages\sklearn\base.py:175: DeprecationWarning: inspect.getargspec() is deprecated, use inspect.signature() instead forest=forest.fit( args, varargs, kw, default = inspect.getargspec(init)

C:\Anaconda3\lib\site-packages\sklearn\base.py:175: DeprecationWarning: inspect.getargspec() is deprecated, use inspect.signature() instead args, varargs, kw, default = inspect.getargspec(init)

Does anyone know what this error means?

It looks like getargspec was deprecated since Python 3.0(see getargspec doc), so you are getting warnings (not errors) when it gets called. It is used a lot in sklearn.

There is some discussion of this on the scikit-learn issue tracker. It was raised here and fixed here. It has been fixed for 0.17, the current stable release. If the warnings are a problem for you, you should probably just update your sklearn with conda update scikit-learn.
