问题

I keep getting this :

DeprecationWarning: integer argument expected, got float

How do I make this message go away? Is there a way to avoid warnings in Python?

回答1:

From documentation of the warnings module:

 #!/usr/bin/env python -W ignore::DeprecationWarning

If you're on Windows: pass -W ignore::DeprecationWarning as an argument to Python. Better though to resolve the issue, by casting to int.

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

I had these:

/home/eddyp/virtualenv/lib/python2.6/site-packages/Twisted-8.2.0-py2.6-linux-x86_64.egg/twisted/persisted/sob.py:12:
DeprecationWarning: the md5 module is deprecated; use hashlib instead import os, md5, sys

/home/eddyp/virtualenv/lib/python2.6/site-packages/Twisted-8.2.0-py2.6-linux-x86_64.egg/twisted/python/filepath.py:12:
DeprecationWarning: the sha module is deprecated; use the hashlib module instead import sha

Fixed it with:

import warnings

with warnings.catch_warnings():
    warnings.filterwarnings("ignore",category=DeprecationWarning)
    import md5, sha

yourcode()

Now you still get all the other DeprecationWarnings, but not the ones caused by:

import md5, sha

回答3:

You should just fix your code but just in case,

import warnings
warnings.filterwarnings("ignore", category=DeprecationWarning)

回答4:

I found the cleanest way to do this (especially on windows) is by adding the following to C:\Python26\Lib\site-packages\sitecustomize.py:

import warnings
warnings.filterwarnings("ignore", category=DeprecationWarning)

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

None of these answers worked for me so I will post my way to solve this. I use the following at the beginning of my main.py script and it works fine.

Use the following as it is (copy-paste it):

import "blabla"
import "blabla"

def warn(*args, **kwargs):
    pass
import warnings
warnings.warn = warn

# more code here...
# more code here...

回答6:

Pass the correct arguments? :P

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

回答7:

Convert the argument to int. It's as simple as

int(argument)

回答8:

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

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
    ...

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

Docker Solution

Disable ALL warnings before running the python application
- You can disable your dockerized tests as well

ENV PYTHONWARNINGS="ignore::DeprecationWarning"

回答10:

If you know what you are doing, another way is simply find the file that warns you(the path of the file is shown in warning info), comment the lines that generate the warnings.

回答11:

Python 3

Just write below lines that are easy to remember before writing your code:

import warnings

warnings.filterwarnings("ignore")

回答12:

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. How to redirect python warnings to a custom stream?
