这是一个通过ChatGLM模型训练的李萌萌的数字分身,你可以在问题栏目填入内容,或者什么都不填,来观察李萌萌到底会说些什么。

r"""
|
11 |
+
This is the configuration class to store the configuration of a [`~ChatGLMModel`].
|
12 |
+
It is used to instantiate an ChatGLM model according to the specified arguments, defining the model
|
13 |
+
architecture. Instantiating a configuration with the defaults will yield a similar configuration to that of
|
14 |
+
the ChatGLM-6B [THUDM/ChatGLM-6B](https://huggingface.co/THUDM/chatglm-6b) architecture.
|
15 |
+
|
16 |
+
Configuration objects inherit from [`PretrainedConfig`] and can be used
|
17 |
+
to control the model outputs. Read the documentation from [`PretrainedConfig`]
|
18 |
+
for more information.
|
19 |
+
|
20 |
+
|
21 |
+
Args:
|
22 |
+
vocab_size (`int`, *optional*, defaults to 150528):
|
23 |
+
Vocabulary size of the ChatGLM-6B model. Defines the number of different tokens that can be represented by the
|
24 |
+
`inputs_ids` passed when calling [`~ChatGLMModel`] or
|
25 |
+
[`~TFChatGLMModel`].
|
26 |
+
hidden_size (`int`, *optional*, defaults to 4096):
|
27 |
+
Dimension of the encoder layers and the pooler layer.
|
28 |
+
num_hidden_layers (`int`, *optional*, defaults to 28):
|
29 |
+
Number of hidden layers in the Transformer encoder.
|
30 |
+
num_attention_heads (`int`, *optional*, defaults to 32):
|
31 |
+
Number of attention heads for each attention layer in the Transformer encoder.
|
32 |
+
inner_hidden_size (`int`, *optional*, defaults to 16384):
|
33 |
+
Dimension of the "intermediate" (i.e., feed-forward) layer in the Transformer encoder.
|
34 |
+
max_sequence_length (`int`, *optional*, defaults to 512):
|
35 |
+
The maximum sequence length that this model might ever be used with.
|
36 |
+
Typically set this to something large just in case (e.g., 512 or 1024 or 2048).
|
37 |
+
layernorm_epsilon (`float`, *optional*, defaults to 1e-5):
|
38 |
+
The epsilon used by the layer normalization layers.
|
39 |
+
use_cache (`bool`, *optional*, defaults to `True`):
|
40 |
+
Whether the model should return the last key/values attentions (not used by all models).
|
41 |
+
Example:
|
42 |
+
|
43 |
+
```python

+
The model can behave as an encoder (with only self-attention) as well
|
700 |
+
as a decoder, in which case a layer of cross-attention is added between
|
701 |
+
the self-attention layers, following the architecture described in [Attention is
|
702 |
+
all you need](https://arxiv.org/abs/1706.03762) by Ashish Vaswani,
|
703 |
+
Noam Shazeer, Niki Parmar, Jakob Uszkoreit, Llion Jones, Aidan N. Gomez, Lukasz Kaiser and Illia Polosukhin.
|
704 |
+
|
705 |
+
To behave as an decoder the model needs to be initialized with the
|
706 |
+
`is_decoder` argument of the configuration set to `True`.
|
707 |
+
To be used in a Seq2Seq model, the model needs to initialized with both `is_decoder`
|
708 |
+
argument and `add_cross_attention` set to `True`; an
|
709 |
+
`encoder_hidden_states` is then expected as an input to the forward pass.
