    head_ratio (`int`, *optional*, defaults to 2):
        Ratio gamma to reduce the number of attention heads.
    num_groups (`int`, *optional*, defaults to 1):
        The number of groups for grouped linear layers for ConvBert model

    Example:

    ```python
    >>> from transformers import ConvBertConfig, ConvBertModel

    >>> # Initializing a ConvBERT convbert-base-uncased style configuration
    >>> configuration = ConvBertConfig()

    >>> # Initializing a model (with random weights) from the convbert-base-uncased style configuration
    >>> model = ConvBertModel(configuration)

    >>> # Accessing the model configuration
    >>> configuration = model.config
