Keras throws ValueError: For a `build()` method with more than one argument, all arguments should have a `_shape` suffix [Reproduced in 3 platforms]

I reproduced this error in three platforms. Apparently it was appearing with python 3.10.8 version

after checking with couple of other versions after python 3.10.8 I thought it might be related to a bug in python itself and there is something important about inspect module which may be related to issue here. I think this may be the one causing the error on all 3 platforms with many different versions of keras. python.org - changelog- gh-74044

And this one I think what we are having here link

"When obtaining the signature of a bound method, inspect.signature, by default, omits the "self" argument to the method, since it is already specified in the bound method. However, if you create a wrapper around a bound method with functools.update_wrapper() or @functools.wraps, calling inspect.signature on the wrapper will return a signature which includes the "self" argument.

Reproducer:

    import inspect
    import functools

    class Foo(object):
        def bar(self, testarg):
            pass

    f = Foo()

    @functools.wraps(f.bar)
    def baz(*args):
        f.bar(*args)


    assert inspect.signature(baz) == inspect.signature(f.bar)

Thank you for investigating the issue. Since it is far upstream and only affects one specific Python patch, I think the best we could do would be to exclude 3.10.8 from the install requirements, e.g. with

requires-python = ">= 3.10, < 3.13, != 3.10.8"

@stefanradev93 What do you think?
