The prompt encoder network that is used to generate the virtual token embeddings for p-tuning.

Args:
    config ([`PromptEncoderConfig`]): The configuration of the prompt encoder.

Example:

```py
>>> from peft import PromptEncoder, PromptEncoderConfig

>>> config = PromptEncoderConfig(
...     peft_type="P_TUNING",
...     task_type="SEQ_2_SEQ_LM",
...     num_virtual_tokens=20,
...     token_dim=768,
...     num_transformer_submodules=1,
...     num_attention_heads=12,
...     num_layers=12,
...     encoder_reparameterization_type="MLP",
...     encoder_hidden_size=768,
... )

>>> prompt_encoder = PromptEncoder(config)
```

**Attributes**:
    - **embedding** (`torch.nn.Embedding`) -- The embedding layer of the prompt encoder.
    - **mlp_head** (`torch.nn.Sequential`) -- The MLP head of the prompt encoder if `inference_mode=False`.
    - **lstm_head** (`torch.nn.LSTM`) -- The LSTM head of the prompt encoder if `inference_mode=False` and
    `encoder_reparameterization_type="LSTM"`.
    - **token_dim** (`int`) -- The hidden embedding dimension of the base transformer model.
    - **input_size** (`int`) -- The input size of the prompt encoder.
    - **output_size** (`int`) -- The output size of the prompt encoder.
    - **hidden_size** (`int`) -- The hidden size of the prompt encoder.
    - **total_virtual_tokens** (`int`): The total number of virtual tokens of the
    prompt encoder.
    - **encoder_type** (Union[[`PromptEncoderReparameterizationType`], `str`]): The encoder type of the prompt
      encoder.


Input shape: (`batch_size`, `total_virtual_tokens`)

Output shape: (`batch_size`, `total_virtual_tokens`, `token_dim`)
