class InternLM3Config(PretrainedConfig):
|
28 |
+
r"""
|
29 |
+
This is the configuration class to store the configuration of a [`InternLM2Model`]. It is used to instantiate
|
30 |
+
an InternLM2 model according to the specified arguments, defining the model architecture. Instantiating a
|
31 |
+
configuration with the defaults will yield a similar configuration to that of the InternLM2-7B.
|
32 |
+
|
33 |
+
Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
|
34 |
+
documentation from [`PretrainedConfig`] for more information.
|
35 |
+
|
36 |
+
|
37 |
+
Args:
|
38 |
+
vocab_size (`int`, *optional*, defaults to 151936):
|
39 |
+
Vocabulary size of the InternLM3 model. Defines the number of different tokens that can be represented by the
|
40 |
+
`inputs_ids` passed when calling [`InternLM3Model`]
|
41 |
+
hidden_size (`int`, *optional*, defaults to 4096):
|
42 |
+
Dimension of the hidden representations.
|
43 |
+
intermediate_size (`int`, *optional*, defaults to 22016):
|
44 |
+
Dimension of the MLP representations.
|
45 |
+
num_hidden_layers (`int`, *optional*, defaults to 32):
|
46 |
+
Number of hidden layers in the Transformer encoder.
|
47 |
+
num_attention_heads (`int`, *optional*, defaults to 32):
|
48 |
+
Number of attention heads for each attention layer in the Transformer encoder.
|
49 |
+
num_key_value_heads (`int`, *optional*, defaults to 32):
|
50 |
+
This is the number of key_value heads that should be used to implement Grouped Query Attention. If
|
51 |
+
`num_key_value_heads=num_attention_heads`, the model will use Multi Head Attention (MHA), if
|
52 |
+
`num_key_value_heads=1` the model will use Multi Query Attention (MQA) otherwise GQA is used. When
|
53 |
+
converting a multi-head checkpoint to a GQA checkpoint, each group key and value head should be constructed
|
54 |
+
by meanpooling all the original heads within that group. For more details checkout [this
|
55 |
+
paper](https://arxiv.org/pdf/2305.13245.pdf). If it is not specified, will default to `32`.
|
56 |
+
hidden_act (`str` or `function`, *optional*, defaults to `"silu"`):
|
57 |
+
The non-linear activation function (function or string) in the decoder.
|
58 |
+
max_position_embeddings (`int`, *optional*, defaults to 32768):
|
59 |
+
The maximum sequence length that this model might ever be used with.
|
60 |
+
initializer_range (`float`, *optional*, defaults to 0.02):
|
61 |
+
The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
|
62 |
+
rms_norm_eps (`float`, *optional*, defaults to 1e-06):
|
63 |
+
The epsilon used by the rms normalization layers.
|
64 |
+
use_cache (`bool`, *optional*, defaults to `True`):
|
65 |
+
Whether or not the model should return the last key/values attentions (not used by all models). Only
|
66 |
+
relevant if `config.is_decoder=True`.
|
67 |
+
tie_word_embeddings (`bool`, *optional*, defaults to `False`):
|
68 |
+
Whether the model's input and output word embeddings should be tied.
|
69 |
+
rope_theta (`float`, *optional*, defaults to 10000.0):
|
70 |
+
The base period of the RoPE embeddings.
|
71 |
+
rope_scaling (`Dict`, *optional*):
|
72 |
+
Dictionary containing the scaling configuration for the RoPE embeddings. NOTE: if you apply new rope type
|
73 |
+
and you expect the model to work on longer `max_position_embeddings`, we recommend you to update this value
|
74 |
+
accordingly.
|
75 |
+
Expected contents:
|
76 |
+
`rope_type` (`str`):
|
77 |

|
79 |
+
`factor` (`float`, *optional*):
|
80 |
+
Used with all rope types except 'default'. The scaling factor to apply to the RoPE embeddings. In
|
81 |
+
most scaling types, a `factor` of x will enable the model to handle sequences of length x *

+
`attention_factor` (`float`, *optional*):
|
87 |
+
Used with 'yarn' and 'longrope'. The scaling factor to be applied on the attention

+
`original_max_position_embeddings`). Must be a list of numbers with the same length as the hidden
|
99 |
+
size divided by the number of attention heads divided by 2
|
100 |
+
`long_factor` (`List[float]`, *optional*):
|
101 |
+
Only used with 'longrope'. The scaling factor to be applied to long contexts (<
|
102 |
+
`original_max_position_embeddings`). Must be a list of numbers with the same length as the hidden
|
103 |
+
size divided by the number of attention heads divided by 2
|
104 |
+
`low_freq_factor` (`float`, *optional*):
|
105 |
+

|
106 |
+
`high_freq_factor` (`float`, *optional*):
|
107 |
+
Only used with 'llama3'. Scaling factor applied to high frequency components of the RoPE
|
108 |
+
qkv_bias (`bool`, *optional*, defaults to `False`):
|
109 |
+
Whether to use a bias in the query, key and value projection layers during self-attention.
|
110 |
+
attention_dropout (`float`, *optional*, defaults to 0.0):
|
111 |
+
The dropout ratio for the attention probabilities.
|
112 |
+
bias (`bool`, *optional*, defaults to `False`):
|
113 |
+

|
114 |
+
head_dim (`int`, *optional*):

This model inherits from [`PreTrainedModel`]. Check the superclass documentation for the generic methods the
|
667 |

library implements for all its model (such as downloading or saving, resizing the input embeddings, pruning heads
|
668 |
+
etc.)
|
669 |

|
670 |
+
This model is also a PyTorch [torch.nn.Module](https://pytorch.org/docs/stable/nn.html#torch.nn.Module) subclass.
|
671 |

Use it as a regular PyTorch Module and refer to the PyTorch documentation for all matter related to general usage
|
672 |
+
and behavior.

Model configuration class with all the parameters of the model. Initializing with a config file does not
|
677 |

Indices of input sequence tokens in the vocabulary. Padding will be ignored by default should you provide
|
714 |
+
it.
|
715 |
+
|
716 |
+
Indices can be obtained using [`AutoTokenizer`]. See [`PreTrainedTokenizer.encode`] and

[`PreTrainedTokenizer.__call__`] for details.

[What are input IDs?](../glossary#input-ids)
|
720 |
+
attention_mask (`torch.Tensor` of shape `(batch_size, sequence_length)`, *optional*):
|
721 |
+
Mask to avoid performing attention on padding token indices. Mask values selected in `[0, 1]`:
|
722 |
+
|
723 |
+
- 1 for tokens that are **not masked**,
|
724 |
+
- 0 for tokens that are **masked**.

|
729 |
+
[`PreTrainedTokenizer.__call__`] for details.
|
730 |
+
|
731 |
+
If `past_key_values` is used, optionally only the last `input_ids` have to be input (see
|
732 |
+
`past_key_values`).
|
733 |
+
|
734 |
+
If you want to change padding behavior, you should read [`modeling_opt._prepare_decoder_attention_mask`]
|
735 |
+
and modify to your needs. See diagram 1 in [the paper](https://arxiv.org/abs/1910.13461) for more
|
736 |
+
information on the default strategy.
|
737 |
+
|
738 |
+
- 1 indicates the head is **not masked**,
|
739 |
+
- 0 indicates the head is **masked**.
|
740 |
+
position_ids (`torch.LongTensor` of shape `(batch_size, sequence_length)`, *optional*):
|
741 |
+
Indices of positions of each input sequence tokens in the position embeddings. Selected in the range `[0,
|
742 |
+
config.n_positions - 1]`.
|
743 |
+
|
744 |
+
[What are position IDs?](../glossary#position-ids)
|
745 |
+
past_key_values (`Cache` or `tuple(tuple(torch.FloatTensor))`, *optional*):
|
746 |
+
Pre-computed hidden-states (key and values in the self-attention blocks and in the cross-attention
|
747 |
+
blocks) that can be used to speed up sequential decoding. This typically consists in the `past_key_values`
|
748 |
+
returned by the model at a previous stage of decoding, when `use_cache=True` or `config.use_cache=True`.
|
749 |
+
|
750 |
+
Two formats are allowed:
|
751 |
+
- a [`~cache_utils.Cache`] instance, see our
|
752 |
+
[kv cache guide](https://huggingface.co/docs/transformers/en/kv_cache);
|
753 |
+
- Tuple of `tuple(torch.FloatTensor)` of length `config.n_layers`, with each tuple having 2 tensors of
|
754 |
+
shape `(batch_size, num_heads, sequence_length, embed_size_per_head)`). This is also known as the legacy
|
755 |
+
cache format.
|
756 |
+
|
757 |
+
The model will output the same cache format that is fed as input. If no `past_key_values` are passed, the
|
758 |
+
legacy cache format will be returned.
|
759 |
+
|
760 |
+
If `past_key_values` are used, the user can optionally input only the last `input_ids` (those that don't
|
761 |
+
have their past key value states given to this model) of shape `(batch_size, 1)` instead of all `input_ids`
|
762 |
+
of shape `(batch_size, sequence_length)`.
|
763 |
+
inputs_embeds (`torch.FloatTensor` of shape `(batch_size, sequence_length, hidden_size)`, *optional*):
|
764 |
+
Optionally, instead of passing `input_ids` you can choose to directly pass an embedded representation. This
|
765 |
+
is useful if you want more control over how to convert `input_ids` indices into associated vectors than the
|
766 |
+
model's internal embedding lookup matrix.
|
767 |
+
use_cache (`bool`, *optional*):
|
768 |
+
If set to `True`, `past_key_values` key value states are returned and can be used to speed up decoding (see
|
769 |
+
`past_key_values`).
|
770 |
+
output_attentions (`bool`, *optional*):
|
771 |
+
Whether or not to return the attentions tensors of all attention layers. See `attentions` under returned
|
772 |
+
tensors for more detail.
|
773 |
+
output_hidden_states (`bool`, *optional*):
|
774 |
+
Whether or not to return the hidden states of all layers. See `hidden_states` under returned tensors for
|
775 |
+
more detail.
|
776 |
+
return_dict (`bool`, *optional*):
|
777 |
+
Whether or not to return a [`~utils.ModelOutput`] instead of a plain tuple.
|
778 |
+
cache_position (`torch.LongTensor` of shape `(sequence_length)`, *optional*):
|
779 |
+
Indices depicting the position of the input sequence tokens in the sequence. Contrarily to `position_ids`,
|
780 |
+
this tensor is not affected by padding. It is used to update the cache in the correct position and to infer
|
781 |
+
the complete sequence length.

Whether or not to cleanup spaces after decoding, cleanup consists in removing potential artifacts like
|
59 |
+
extra spaces.
|
60 |

use_default_system_prompt (`bool`, *optional*, defaults to `False`):
