|
||||
inputs = tokenizer(text, return_tensors="pt")
|
||||
outputs = model.generate(**inputs.to(model.device), max_new_tokens=100)

|

class DeepseekConfig(PretrainedConfig):
|
||||
r"""
|
||||
This is the configuration class to store the configuration of a [`DeepseekModel`]. It is used to instantiate an DeepSeek
|
||||
model according to the specified arguments, defining the model architecture. Instantiating a configuration with the
|
||||
defaults will yield a similar configuration to that of the DeepSeek-7B.
|
||||
|
||||
Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
|
||||
documentation from [`PretrainedConfig`] for more information.
|
||||
|
||||
|
||||
Args:
|
||||
vocab_size (`int`, *optional*, defaults to 102400):
|
||||
Vocabulary size of the Deep model. Defines the number of different tokens that can be represented by the
|
||||
`inputs_ids` passed when calling [`DeepseekModel`]
|
||||
hidden_size (`int`, *optional*, defaults to 4096):
|
||||
Dimension of the hidden representations.
|
||||
intermediate_size (`int`, *optional*, defaults to 11008):
|
||||
Dimension of the MLP representations.
|
||||
moe_intermediate_size (`int`, *optional*, defaults to 1407):
|
||||
Dimension of the MoE representations.
|
||||

|
||||
Number of hidden layers in the Transformer decoder.

||||
num_attention_heads (`int`, *optional*, defaults to 32):
|
||||
Number of attention heads for each attention layer in the Transformer decoder.
|
||||
n_shared_experts (`int`, *optional*, defaults to None):
|
||||
Number of shared experts, None means dense model.
|
||||
n_routed_experts (`int`, *optional*, defaults to None):
|
||||
Number of routed experts, None means dense model.
|
||||
num_experts_per_tok (`int`, *optional*, defaults to None):
|
||||
Number of selected experts, None means dense model.
|
||||
moe_layer_freq (`int`, *optional*, defaults to 1):
|
||||
The frequency of the MoE layer: one expert layer for every `moe_layer_freq - 1` dense layers.
|
||||
first_k_dense_replace (`int`, *optional*, defaults to 0):
|
||||
Number of dense layers in shallow layers(embed->dense->dense->...->dense->moe->moe...->lm_head).
|
||||
\--k dense layers--/
|
||||
norm_topk_prob (`bool`, *optional*, defaults to False):
|
||||
Whether to normalize the weights of the routed experts.
|
||||

|
||||
Method of computing expert weights.
|
||||

|
||||
seq_aux = (`bool`, *optional*, defaults to True):
|
||||
Whether to compute the auxiliary loss for each individual sample.
|
||||
num_key_value_heads (`int`, *optional*):
|
||||
This is the number of key_value heads that should be used to implement Grouped Query Attention. If
|
||||
`num_key_value_heads=num_attention_heads`, the model will use Multi Head Attention (MHA), if
|
||||
`num_key_value_heads=1 the model will use Multi Query Attention (MQA) otherwise GQA is used. When
|
||||
converting a multi-head checkpoint to a GQA checkpoint, each group key and value head should be constructed
|
||||
by meanpooling all the original heads within that group. For more details checkout [this
|
||||
paper](https://arxiv.org/pdf/2305.13245.pdf). If it is not specified, will default to
|
||||
`num_attention_heads`.

|
||||

|
||||
Experimental feature. Tensor parallelism rank used during pretraining. Please refer to [this
|
||||
document](https://huggingface.co/docs/transformers/parallelism) to understand more about it. This value is
|
||||
necessary to ensure exact reproducibility of the pretraining results. Please refer to [this
|
||||
issue](https://github.com/pytorch/pytorch/issues/76232).
|

|
||||
`max_position_embeddings` to the expected new maximum.
|
||||
attention_bias (`bool`, defaults to `False`, *optional*, defaults to `False`):
|
||||
