Python 2.7 warning: __init__ not compatible to __new__

Question

I have a class defined in Python 2.7 like this:

from future.builtins import object


class Point(object):

    def __init__(self, x, y):
        self.x = x
        self.y = y

In PyCharm, this gives a warning in the __init__ line:

Signature is not compatible to __new__.

I don't understand what this warning is telling me. Can someone give an example where this warning would rightfully catch an error or can this warning be turned off?

There's a PyCharm thread for this, but it doesn't help me: https://intellij-support.jetbrains.com/hc/en-us/community/posts/115000254530-PyCharm-init-Signature-is-not-compatible-to-new-

Answer 1

I suffered from the same problem and found the solution in here.

As discussed in the above link, a direct solution is to remove your Pycharm config directory ("/home/username/.PyCharm2018.3" for me). However, it would remove all your other configs too. Finally, I just fix the problem by removing the rule from inspections. You can find the rule in the Pycharm Setting window (see the figure as follow).
