From documentation of the <a href="https://docs.python.org/3/library/warnings.html" rel="noreferrer"><code>warnings</code> module</a>:

<pre><code> #!/usr/bin/env python -W ignore::DeprecationWarning
</code></pre>

If you're on Windows: pass <code>-W ignore::DeprecationWarning</code> as an argument to Python. Better though to resolve the issue, by casting to <a href="http://docs.python.org/3.0/library/functions.html#int" rel="noreferrer">int</a>.

(Note that in Python 3.2, deprecation warnings are ignored by default.)

<pre><code>import warnings

Note that I had to create this file. Of course, change the path to python if yours is different.

On the more serious note, you can pass the argument -Wi::DeprecationWarning on the command line to the interpreter to ignore the deprecation warnings.

When you want to ignore warnings only in functions you can do the following.

<pre><code>import warnings
from functools import wraps


def ignore_warnings(f):
 @wraps(f)
 def inner(*args, **kwargs):
 with warnings.catch_warnings(record=True) as w:
 warnings.simplefilter("ignore")
 response = f(*args, **kwargs)
 return response
 return inner

@ignore_warnings
def foo(arg1, arg2):
 ...
 write your code here without warnings
 ...

@ignore_warnings
def foo2(arg1, arg2, arg3):
 ...
 write your code here without warnings
 ...
</code></pre>

Just add the @ignore_warnings decorator on the function you want to ignore all warnings

If you are using logging (<a href="https://docs.python.org/3/library/logging.html" rel="nofollow noreferrer">https://docs.python.org/3/library/logging.html</a>) to format or redirect your ERROR, NOTICE, and DEBUG messages, you can redirect the WARNINGS from the warning system to the logging system:
<pre><code>logging.captureWarnings(True)

See <a href="https://docs.python.org/3/library/warnings.html" rel="nofollow noreferrer">https://docs.python.org/3/library/warnings.html</a> and <a href="https://docs.python.org/3/library/logging.html#logging.captureWarnings" rel="nofollow noreferrer">https://docs.python.org/3/library/logging.html#logging.captureWarnings</a>
In my case, I was formatting all the exceptions with the logging system, but warnings (e.g. scikit-learn) were not affected.

Not to beat you up about it but you are being warned that what you are doing will likely stop working when you next upgrade python. Convert to int and be done with it.

BTW. You can also write your own warnings handler. Just assign a function that does nothing.

我一直收到这样的信息：DeprecationWarning: integer argument expected, got float怎样才能让这条消息消失呢？在Python中有没有避免警告的方法？
