Here is an example of how you can add a docstring:

```python
class SeamlessM4Tv2ForTextToSpeech(metaclass=DummyObject):
    """
    Class providing SeamlessM4Tv2 model instance for Text-to-Speech functionality.
    """

    _backends = ["torch"]

    def __init__(self, *args, **kwargs):


SUMMARY:
**Summary:**

The `XmodForMaskedLM` class is a PyTorch-based masked language modeling implementation.

*   **Main purpose and functionality:** This class serves as a pre-trained library for masked language models using the transformer architecture, with support specifically designed for masked LM tasks.
*   **Key implementation details:**
    *   The class requires PyTorch backend.
    *   It uses the `requires_backends` function to check if the required PyTorch backend is available (in this case, "torch").
*   **Notable dependencies or requirements:** The class utilizes PyTorch (`torch`) for its core functionality.

**Detailed Analysis:**

The provided code snippet showcases a class with the following distinct features:

1.  `metaclass=DummyObject`: This line sets the metaclass of the `XmodForMaskedLM` class to `DummyObject`. However, the purpose and implementation of this setting are unclear as the `DummyObject` is not defined in the snippet.

2.  `_backends = ["torch"]`: The `_backends` attribute specifies a list containing `"torch"`, indicating that PyTorch is the intended backend for this class.

3.  `requires_backends(self, ["torch"])`: This method verifies if the required backend (`torch`) is accessible in the environment where the class instance will be used.

To further analyze and document this class, additional information such as the complete implementation of `DummyObject` (if applicable), specific details about the transformer architecture used for masked LM tasks, or other relevant aspects like hyperparameters or training procedures would be needed. However, based on the provided code snippet alone, its focus appears to lie in ensuring compatibility with PyTorch, particularly `"torch"`.

    Function or method decorator to notify users about deprecated keyword arguments, replacing them with a new name if specified.

    This decorator allows you to:
    - Notify users when a keyword argument is deprecated.
    - Automatically replace deprecated keyword arguments with new ones.
    - Raise an error if deprecated arguments are used, depending on the specified conditions.

    By default, the decorator notifies the user about the deprecated argument while the `transformers.__version__` < specified `version`
    in the decorator. To keep notifications with any version `warn_if_greater_or_equal_version=True` can be set.

    Parameters:
        old_name (`str`):
            Name of the deprecated keyword argument.
        version (`str`):
            The version in which the keyword argument was (or will be) deprecated.
        new_name (`Optional[str]`, *optional*):
            The new name for the deprecated keyword argument. If specified, the deprecated keyword argument will be replaced with this new name.
        warn_if_greater_or_equal_version (`bool`, *optional*, defaults to `False`):
            Whether to show warning if current `transformers` version is greater or equal to the deprecated version.
        raise_if_greater_or_equal_version (`bool`, *optional*, defaults to `False`):
            Whether to raise `ValueError` if current `transformers` version is greater or equal to the deprecated version.
        raise_if_both_names (`bool`, *optional*, defaults to `False`):
            Whether to raise `ValueError` if both deprecated and new keyword arguments are set.
        additional_message (`Optional[str]`, *optional*):
            An additional message to append to the default deprecation message.

    Raises:
        ValueError:
            If raise_if_greater_or_equal_version is True and the current version is greater than or equal to the deprecated version, or if raise_if_both_names is True and both old and new keyword arguments are provided.

    Returns:
        Callable:
            A wrapped function that handles the deprecated keyword arguments according to the specified parameters.

    Example usage with renaming argument:

SUMMARY:
**TrialShortNamer Class Summary**

**Purpose and Functionality**
---------------------------

The `TrialShortNamer` class is designed to generate short names for trial parameter names. It takes into account prefixes, default values, and boolean values in the name generation process.

**Key Implementation Details**
-------------------------------

*   The `shortname_for_word` method determines a shortened version of a given word by extracting prefixes from the longest possible length.
*   The `shortname_for_key` method generates a short name for a parameter key based on its component words, handling separators and collisions.
*   The `add_new_param_name` method adds a new parameter with its corresponding shortened name to the naming information.
*   The `build_naming_info` method initializes the naming information with default values and field keys.

**Notable Dependencies or Requirements**
-----------------------------------------

*   The class relies on external dictionaries (`"short_word"`, `"reverse_short_word"`, `"short_param"`), which are built during the `build_naming_info` process.
*   It also utilizes regex for parsing parameter names in the `parse_repr` method.

**Class Relationships and Inheritance**
----------------------------------------

The class does not inherit from any other classes; it is a standalone implementation.
