29 |
+
1. Definitions.

30 |
+
|
31 |
+
"License" shall mean the terms and conditions for use, reproduction,

|
41 |
+
direction or management of such entity, whether by contract or

|
49 |
+
including but not limited to software source code, documentation
|
50 |

and conversions to other media types.
|
56 |
+
|
57 |
+
"Work" shall mean the work of authorship, whether in Source or
|
58 |
+
Object form, made available under the License, as indicated by a

(an example is provided in the Appendix below).
|
61 |
+
|
62 |
+
"Derivative Works" shall mean any work, whether in Source or Object

+
form, that is based on (or derived from) the Work and for which the
|
64 |
+
editorial revisions, annotations, elaborations, or other modifications
|
65 |
+
represent, as a whole, an original work of authorship. For the purposes
|
66 |
+
of this License, Derivative Works shall not include works that remain
|
67 |
+
separable from, or merely link (or bind by name) to the interfaces of,
|
68 |
+
the Work and Derivative Works thereof.
|
69 |
+
|
70 |
+
"Contribution" shall mean any work of authorship, including
|
71 |
+
the original version of the Work and any modifications or additions
|
72 |
+
to that Work or Derivative Works thereof, that is intentionally
|
73 |
+
submitted to Licensor for inclusion in the Work by the copyright owner
|
74 |
+
or by an individual or Legal Entity authorized to submit on behalf of
|
75 |
+
the copyright owner. For the purposes of this definition, "submitted"
|
76 |
+
means any form of electronic, verbal, or written communication sent
|
77 |
+
to the Licensor or its representatives, including but not limited to
|
78 |
+
communication on electronic mailing lists, source code control systems,
|
79 |
+
and issue tracking systems that are managed by, or on behalf of, the
|
80 |
+
Licensor for the purpose of discussing and improving the Work, but
|
81 |
+
excluding communication that is conspicuously marked or otherwise
|
82 |
+
designated in writing by the copyright owner as "Not a Contribution."
|
83 |
+
|
84 |
+
"Contributor" shall mean Licensor and any individual or Legal Entity
|
85 |
+
on behalf of whom a Contribution has been received by Licensor and
|
86 |
+
subsequently incorporated within the Work.
|
87 |
+
|
88 |
+
2. Grant of Copyright License. Subject to the terms and conditions of
|
89 |
+
this License, each Contributor hereby grants to You a perpetual,
|
90 |
+
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
91 |
+
copyright license to reproduce, prepare Derivative Works of,
|
92 |
+
publicly display, publicly perform, sublicense, and distribute the
|
93 |
+
Work and such Derivative Works in Source or Object form.
|
94 |
+
|
95 |
+
3. Grant of Patent License. Subject to the terms and conditions of
|
96 |
+
this License, each Contributor hereby grants to You a perpetual,
|
97 |
+
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
98 |
+
(except as stated in this section) patent license to make, have made,
|
99 |
+
use, offer to sell, sell, import, and otherwise transfer the Work,
|
100 |
+
where such license applies only to those patent claims licensable
|
101 |
+
by such Contributor that are necessarily infringed by their
|
102 |
+
Contribution(s) alone or by combination of their Contribution(s)
|
103 |
+
with the Work to which such Contribution(s) was submitted. If You
|
104 |
+
institute patent litigation against any entity (including a
|
105 |
+
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
106 |
+
or a Contribution incorporated within the Work constitutes direct
|
107 |
+
or contributory patent infringement, then any patent licenses
|
108 |
+
granted to You under this License for that Work shall terminate
|
109 |
+
as of the date such litigation is filed.
|
110 |
+
|
111 |
+
4. Redistribution. You may reproduce and distribute copies of the
|
112 |
+
Work or Derivative Works thereof in any medium, with or without
|
113 |
+
modifications, and in Source or Object form, provided that You
|
114 |
+
meet the following conditions:
|
115 |
+
|
116 |
+
(a) You must give any other recipients of the Work or
|
117 |
+
Derivative Works a copy of this License; and
|
118 |
+
|
119 |
+
(b) You must cause any modified files to carry prominent notices
|
120 |
+
stating that You changed the files; and
|
121 |
+
|
122 |
+
(c) You must retain, in the Source form of any Derivative Works
|
123 |
+
that You distribute, all copyright, patent, trademark, and
|
124 |
+
attribution notices from the Source form of the Work,
|
125 |
+
excluding those notices that do not pertain to any part of
|
126 |
+
the Derivative Works; and
|
127 |
+
|
128 |
+
(d) If the Work includes a "NOTICE" text file as part of its
|
129 |
+
distribution, then any Derivative Works that You distribute must
|
130 |
+
include a readable copy of the attribution notices contained
|
131 |
+
within such NOTICE file, excluding those notices that do not
|
132 |
+
pertain to any part of the Derivative Works, in at least one
|
133 |
+
of the following places: within a NOTICE text file distributed
|
134 |
+
as part of the Derivative Works; within the Source form or
|
135 |
+
documentation, if provided along with the Derivative Works; or,
|
136 |
+
within a display generated by the Derivative Works, if and
|
137 |
+
wherever such third-party notices normally appear. The contents
|
138 |
+
of the NOTICE file are for informational purposes only and
|
139 |
+
do not modify the License. You may add Your own attribution
|
140 |
+
notices within Derivative Works that You distribute, alongside
|
141 |
+
or as an addendum to the NOTICE text from the Work, provided
|
142 |
+
that such additional attribution notices cannot be construed
|
143 |
+
as modifying the License.
|
144 |
+
|
145 |
+
You may add Your own copyright statement to Your modifications and
|
146 |
+
may provide additional or different license terms and conditions
|
147 |
+
for use, reproduction, or distribution of Your modifications, or
|
148 |
+
for any such Derivative Works as a whole, provided Your use,
|
149 |
+
reproduction, and distribution of the Work otherwise complies with
|
150 |
+
the conditions stated in this License.
|
151 |
+
|
152 |
+
5. Submission of Contributions. Unless You explicitly state otherwise,
|
153 |
+
any Contribution intentionally submitted for inclusion in the Work
|
154 |
+
by You to the Licensor shall be under the terms and conditions of
|
155 |
+
this License, without any additional terms or conditions.
|
156 |
+
Notwithstanding the above, nothing herein shall supersede or modify
|
157 |
+
the terms of any separate license agreement you may have executed
|
158 |
+
with Licensor regarding such Contributions.
|
159 |
+
|
160 |
+
6. Trademarks. This License does not grant permission to use the trade
|
161 |
+
names, trademarks, service marks, or product names of the Licensor,
|
162 |
+
except as required for reasonable and customary use in describing the
|
163 |
+
origin of the Work and reproducing the content of the NOTICE file.
|
164 |
+
|
165 |
+
7. Disclaimer of Warranty. Unless required by applicable law or
|
166 |
+
agreed to in writing, Licensor provides the Work (and each
|
167 |
+
Contributor provides its Contributions) on an "AS IS" BASIS,
|
168 |
+
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
169 |
+
implied, including, without limitation, any warranties or conditions
|
170 |
+
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
171 |
+
PARTICULAR PURPOSE. You are solely responsible for determining the
|
172 |
+
appropriateness of using or redistributing the Work and assume any
|
173 |
+
risks associated with Your exercise of permissions under this License.
|
174 |
+
|
175 |
+
8. Limitation of Liability. In no event and under no legal theory,
|
176 |
+
whether in tort (including negligence), contract, or otherwise,
|
177 |
+
unless required by applicable law (such as deliberate and grossly
|
178 |
+
negligent acts) or agreed to in writing, shall any Contributor be
|
179 |
+
liable to You for damages, including any direct, indirect, special,
|
180 |
+
incidental, or consequential damages of any character arising as a
|
181 |
+
result of this License or out of the use or inability to use the
|
182 |
+
Work (including but not limited to damages for loss of goodwill,
|
183 |
+
work stoppage, computer failure or malfunction, or any and all
|
184 |
+
other commercial damages or losses), even if such Contributor
|
185 |
+
has been advised of the possibility of such damages.
|
186 |
+
|
187 |
+
9. Accepting Warranty or Additional Liability. While redistributing
|
188 |
+
the Work or Derivative Works thereof, You may choose to offer,
|
189 |
+
and charge a fee for, acceptance of support, warranty, indemnity,
|
190 |
+
or other liability obligations and/or rights consistent with this
|
191 |
+
License. However, in accepting such obligations, You may act only
|
192 |
+
on Your own behalf and on Your sole responsibility, not on behalf
|
193 |
+
of any other Contributor, and only if You agree to indemnify,
|
194 |
+
defend, and hold each Contributor harmless for any liability
|
195 |
+
incurred by, or claims asserted against, such Contributor by reason
|
196 |
+
of your accepting any such warranty or additional liability.
|
197 |

|
33 |
+
This is the configuration class to store the configuration of a [`Phi3Model`]. It is used to instantiate a Phi-3
|
34 |
+
model according to the specified arguments, defining the model architecture. Instantiating a configuration with the
|
35 |
+
defaults will yield a similar configuration to that of the
|
36 |
+
[microsoft/Phi-3-mini-4k-instruct](https://huggingface.co/microsoft/Phi-3-mini-4k-instruct).
|
37 |
+
|
38 |
+
Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
|
39 |
+
documentation from [`PretrainedConfig`] for more information.
|
40 |
+
|
41 |
+
Args:
|
42 |
+
vocab_size (`int`, *optional*, defaults to 32064):
|
43 |
+
Vocabulary size of the Phi-3 model. Defines the number of different tokens that can be represented by the
|
44 |
+
`inputs_ids` passed when calling [`Phi3Model`].
|
45 |
+
hidden_size (`int`, *optional*, defaults to 3072):
|
46 |
+
Dimension of the hidden representations.
|
47 |
+
intermediate_size (`int`, *optional*, defaults to 8192):
|
48 |
+
Dimension of the MLP representations.
|
49 |
+
num_hidden_layers (`int`, *optional*, defaults to 32):
|
50 |
+
Number of hidden layers in the Transformer decoder.
|
51 |
+
num_attention_heads (`int`, *optional*, defaults to 32):
|
52 |
+
Number of attention heads for each attention layer in the Transformer decoder.
|
53 |
+
num_key_value_heads (`int`, *optional*):
|
54 |
+
This is the number of key_value heads that should be used to implement Grouped Query Attention. If
|
55 |
+
`num_key_value_heads=num_attention_heads`, the model will use Multi Head Attention (MHA), if
|
56 |
+
`num_key_value_heads=1 the model will use Multi Query Attention (MQA) otherwise GQA is used. When
|
57 |
+
converting a multi-head checkpoint to a GQA checkpoint, each group key and value head should be constructed
|
58 |
+
by meanpooling all the original heads within that group. For more details checkout [this
|
59 |
+
paper](https://arxiv.org/pdf/2305.13245.pdf). If it is not specified, will default to
|
60 |
+
`num_attention_heads`.
|
61 |
+
resid_pdrop (`float`, *optional*, defaults to 0.0):
|
62 |
+

|
66 |
+
The dropout ratio after computing the attention scores.
|
67 |
+
hidden_act (`str` or `function`, *optional*, defaults to `"silu"`):
|
68 |
+
The non-linear activation function (function or string) in the decoder.
|
69 |
+
max_position_embeddings (`int`, *optional*, defaults to 4096):
|
70 |
+
The maximum sequence length that this model might ever be used with.
|
71 |
+
original_max_position_embeddings (`int`, *optional*, defaults to 4096):
|
72 |
+
The maximum sequence length that this model was trained with. This is used to determine the size of the
|
73 |
+
original RoPE embeddings when using long scaling.
|
74 |
+
initializer_range (`float`, *optional*, defaults to 0.02):
|
75 |

+
The base period of the RoPE embeddings.
|
85 |
+
rope_scaling (`dict`, *optional*):
|
86 |
+
The scaling strategy for the RoPE embeddings. If `None`, no scaling is applied. If a dictionary, it must
|
87 |
+
contain the following keys: `type`, `short_factor` and `long_factor`. The `type` must be either `su` or `yarn` and
|
88 |
+
the `short_factor` and `long_factor` must be lists of numbers with the same length as the hidden size
|
89 |
+
divided by the number of attention heads divided by 2.
|
90 |
+
bos_token_id (`int`, *optional*, defaults to 1):
|
91 |
+
