Eliminating warnings from scikit-learn
提问by Chris Fonnesbeck
I would like to ignore warnings from all packages when I am teaching, but scikit-learn seems to work around the use of the warningspackage to control this. For example:
我想在教学时忽略所有包的警告，但 scikit-learn 似乎可以解决使用warnings包来控制这一点。例如：
with warnings.catch_warnings():
warnings.simplefilter("ignore")
from sklearn import preprocessing
/usr/local/lib/python3.5/site-packages/sklearn/utils/fixes.py:66: DeprecationWarning: inspect.getargspec() is deprecated, use inspect.signature() instead
if 'order' in inspect.getargspec(np.copy)[0]:
/usr/local/lib/python3.5/site-packages/sklearn/utils/fixes.py:358: DeprecationWarning: inspect.getargspec() is deprecated, use inspect.signature() instead
if 'exist_ok' in inspect.getargspec(os.makedirs).args:
Am I using this module incorrectly, or is sklearn doing something its not supposed to?
我是否错误地使用了这个模块，或者 sklearn 做了不应该做的事情？

It annoys me to the extreme that sklearn forces warnings.
sklearn强制发出警告让我非常恼火。
I started using this at the top of main.py:
我开始在 main.py 的顶部使用它：
def warn(*args, **kwargs):
pass
import warnings
warnings.warn = warn
#... import sklearn stuff...

They have changed their warning policy in 2013. You can ignore warnings (also specific types) with something like this:
他们在 2013 年改变了警告政策。您可以使用以下内容忽略警告（也是特定类型）：
import warnings
warnings.filterwarnings("ignore", category=DeprecationWarning)
//EDIT: in the comments below, Reed Richards points out that the filterwarnings call needs to be in the file that calls the function that gives the warning.I hope this helps those who experienced problems with this solution.
