__init__() got an unexpected keyword argument 'bounds'

This error occurs when the `bounds` argument is used in the `__init__()` method of a class that doesn't accept it. The `bounds` argument is typically used in optimization functions to specify constraints on the variables being optimized.

To fix this error, you can either remove the `bounds` argument from the `__init__()` method or modify the class to accept the `bounds` argument. For example:

class MyClass:
    def __init__(self, arg1, arg2):
        # do something with arg1 and arg2
        pass

# If you try to create an instance of MyClass with bounds parameter
obj = MyClass(arg1=1, arg2=2, bounds=[0, 1])
# You will get the error: __init__() got an unexpected keyword argument 'bounds'

# To fix this error, you can modify the class to accept the bounds parameter:
class MyClass:
    def __init__(self, arg1, arg2, bounds=None):
        # do something with arg1 and arg2
        self.bounds = bounds

# Now you can create an instance of MyClass with bounds parameter
obj = MyClass(arg1=1, arg2=2, bounds=[0, 1])
# This will work without any errors
