+
|
| 53 |
+
|
| 54 |
+
## Overview
|
| 55 |
+
|
| 56 |
+
This is a fine-tune of internlm2-20b.
|
| 57 |
+
|
| 58 |
+
See [bagel](https://github.com/jondurbin/bagel) for additional details on the datasets.
|
| 59 |
+
|
| 60 |
+
The DPO version is available [here](https://huggingface.co/jondurbin/bagel-dpo-20b-v04)
|
| 61 |
+
|

## Prompt formatting
|
| 167 |
+
|
| 168 |
+
In sticking with the theme of the bagel, I didn't want to use a single prompt format, so I used 4 - vicuna, llama-2, alpaca, and chat-ml.
|
| 169 |
+
I also didn't want to randomly select a single prompt format for each item (hoping each instruction would generalize more when used in a variety of prompt formats), so each instruction is converted into every prompt format (with 0.75 probability).
|
| 170 |
+
|
| 171 |
+
This means each epoch of our fine-tune is the equivalent of 3 epochs.
|
| 172 |
+
|
| 173 |
+
The default prompt format, which is specified in `chat_template` in the tokenizer config, is llama-2. You can use the `apply_chat_template` method to accurate format prompts, e.g.:
|
| 174 |
+
|
| 175 |
+
```python
|
| 176 |
+
import transformers
|
| 177 |
+
tokenizer = transformers.AutoTokenizer.from_pretrained("jondurbin/bagel-20b-v04", trust_remote_code=True)
|
| 178 |
+
chat = [
|
| 179 |
+
{"role": "system", "content": "You are Bob, a friendly AI assistant."},
|
| 180 |
+
{"role": "user", "content": "Hello, how are you?"},
|
| 181 |
+
{"role": "assistant", "content": "I'm doing great. How can I help you today?"},
|
| 182 |
+
{"role": "user", "content": "I'd like to show off how chat templating works!"},
|
| 183 |
+
]
|
| 184 |
+
print(tokenizer.apply_chat_template(chat, tokenize=False))
|
| 185 |
+
```

+
<summary><b>Alpaca (sort of)</b></summary>
|
| 201 |
+
|
| 202 |
+
The only caveat here for alpaca format is that most of the datasets didn't have a separate `"input"` value, so there is no `### Input:` block - any additional input should just be in the instruction section.
|
| 203 |
+
|
| 204 |
+
```
|
| 205 |
+
Below is an instruction that describes a task. Write a response that appropriately completes the request.
|
| 206 |
+
|
| 207 |
+
### Instruction:
|
| 208 |
+
{system prompt, if provided}
|
| 209 |
+
{instruction}
|
| 210 |
+
|
| 211 |
+
### Response:
|
| 212 |
+
```
|
| 213 |
+
|
| 214 |
+
The main difference here is that because of the dataset formatting and variety of data sources, it would have been much to tedious to add an `### Input:` block, so the inputs are just in the instruction section.

## Prompting strategies
|

<summary>

<b>Context obedient question answering</b>
|
| 242 |
+
<br>
|
| 243 |
+
This is a special prompt format made specifically for answering questions from provided context, e.g. RAG.
|
| 244 |
+
</summary>
|
| 245 |
+
|
| 246 |
+
By obedient, I mean the model was trained to ignore what it thinks it knows, and uses the context to answer the question. The model was also tuned to limit the values to the provided context as much as possible to reduce hallucinations.
|
| 247 |
+
|
| 248 |
+
The format for a closed-context prompt is as follows:
|
| 249 |
+
```
|
| 250 |
+
BEGININPUT
|
| 251 |
+
BEGINCONTEXT
|
| 252 |
+
[key0: value0]
|
| 253 |
+
[key1: value1]
|
| 254 |
+
... other metdata ...
|
| 255 |
+
ENDCONTEXT
|
| 256 |
+
[insert your text blocks here]
|
| 257 |
+
ENDINPUT
|
| 258 |
+
[add as many other blocks, in the exact same format]
|
| 259 |
+
BEGININSTRUCTION
|
| 260 |
+
[insert your instruction(s). The model was tuned with single questions, paragraph format, lists, etc.]
|
| 261 |
+
ENDINSTRUCTION
|
| 262 |
+
```
|
| 263 |
+
|
| 264 |
+
It's also helpful to add "Don't make up answers if you don't know." to your instruction block to make sure if the context is completely unrelated it doesn't make something up.
|
| 265 |
+
|
| 266 |
+
*The __only__ prompts that need this closed context formating are closed-context instructions. Normal questions/instructions do not!*
|
| 267 |
+
|
| 268 |
+
I know it's a bit verbose and annoying, but after much trial and error, using these explicit delimiters helps the model understand where to find the responses and how to associate specific sources with it.
|
| 269 |
+
- `BEGININPUT` - denotes a new input block
|
| 270 |
+
- `BEGINCONTEXT` - denotes the block of context (metadata key/value pairs) to associate with the current input block
|
| 271 |
+
- `ENDCONTEXT` - denotes the end of the metadata block for the current input
|
| 272 |
+
- [text] - Insert whatever text you want for the input block, as many paragraphs as can fit in the context.
|
| 273 |
+
- `ENDINPUT` - denotes the end of the current input block
|
| 274 |
+
- [repeat as many input blocks in this format as you want]
|
| 275 |
+
- `BEGININSTRUCTION` - denotes the start of the list (or one) instruction(s) to respond to for all of the input blocks above.
|
| 276 |
+
- [instruction(s)]
|
| 277 |
+
- `ENDINSTRUCTION` - denotes the end of instruction set
|
| 278 |
+
|
| 279 |
+
It sometimes works without `ENDINSTRUCTION`, but by explicitly including that in the prompt, the model better understands that all of the instructions in the block should be responded to.
|
| 280 |
+
|
| 281 |
+
__Use a very low temperature!__
|
| 282 |
+
|
| 283 |
+
Here's a trivial, but important example to prove the point:
|
| 284 |
+
```
|
| 285 |
+
BEGININPUT
|
| 286 |
+
BEGINCONTEXT
|
| 287 |
+
date: 2021-01-01
|
| 288 |
+
url: https://web.site/123
|
| 289 |
+
ENDCONTEXT
|
| 290 |
+
In a shocking turn of events, blueberries are now green, but will be sticking with the same name.
|
| 291 |
+
ENDINPUT
|
| 292 |
+
BEGININSTRUCTION
|
| 293 |
+
What color are bluberries? Source?
|
| 294 |
+
ENDINSTRUCTION
|
| 295 |
+
```
|
| 296 |
+
|
| 297 |
+
And the response:
|
| 298 |
+
```
|
| 299 |
+
Blueberries are now green.
|
| 300 |
+
Source:
|
| 301 |
+
date: 2021-01-01
|
| 302 |
+
url: https://web.site/123
|
| 303 |
+
```
|
| 304 |
+
|
| 305 |
+
You can also add an instruction similar to the following, to have a more deterministic response when the context doesn't provide an answer to the question:
|
| 306 |
+
|
| 307 |
+
```text
|
| 308 |
+
If you don't know, respond with "IRRELEVANT"
|
| 309 |

You can ask for several possible responses to a given problem, with a ranking and final answer selection.

Example prompt:
|

+
|
| 426 |

```
|
| 427 |
+
A group of people decide to play a round-robin tournament where every player plays every other player exactly once. If a total of 45 games were played, how many players participated in the tournament? Offer several potential answers, rank them according to mathematical logic, and pick the most feasible one.
|
| 428 |
+
```
|
| 429 |
+
|
| 430 |
+
Example response:
|
| 431 |
+
```
|
| 432 |
+
Solution 1:
|
| 433 |
+
In a round-robin tournament, each player plays every other player exactly once. This means that the total number of games played is equal to the combination of all players taken two at a time (since a game involves two players).
|
| 434 |
+
|
| 435 |
+
The formula for combinations is nC2 = n(n-1)/2, where n is the total number of players. We know that nC2 equals 45 (the total number of games), so we can set up the equation as follows:
|
| 436 |
+
|
| 437 |
+
n(n-1)/2 = 45
|
| 438 |
+
|
| 439 |
+
Solving this equation gives us n=10.
|
| 440 |
+
|
| 441 |
+
Final answer: There were 10 players in the tournament.
|
| 442 |
+
|
| 443 |
+
Solution 2:
|
| 444 |
+
Another way to approach this problem is by using the concept of triangular numbers. Triangular numbers are a sequence of numbers where each number can be represented as a triangle with dots. The nth triangular number is given by the sum of the first n natural numbers.
|
| 445 |
+
|
| 446 |
+
If we consider each game as a dot and each player as a side of the triangle, then the total number of games (45) would correspond to the 9th triangular number because 1+2+3+4+5+6+7+8+9=45. However, since each side of the triangle represents a player, and there's one more player than sides in our model (because the last player has no one left to play against), we need to add one more to get the total number of players.
|
| 447 |
+
|
| 448 |
+
Final answer: There were 10 players in the tournament.
|
| 449 |
+
|
| 450 |
+
Solution 3:
|
| 451 |
+
We could also use trial and error to solve this problem. Starting from a small number of players, we calculate how many games would be played in a round-robin tournament until we reach 45 games. For example, with 2 players, only 1 game is played; with 3 players, 3 games are played; with 4 players, 6 games are played, and so on. Continuing this process, we find that with 10 players, 45 games are played.
|
| 452 |
+
|
| 453 |
+
Final answer: There were 10 players in the tournament.
|
| 454 |
+
|
| 455 |
+
Ranking of solutions from best to worst:
|
| 456 |
+
1. Solution 1: This solution uses direct mathematical reasoning based on the properties of a round-robin tournament and solves an equation to find the answer.
|
| 457 |
+
2. Solution 2: This solution uses the concept of triangular numbers which requires additional steps and knowledge beyond the immediate problem context, but still arrives at the correct answer.
|
| 458 |
+
3. Solution 3: This solution relies on trial and error, which is less efficient and reliable than the other methods, but it eventually gets to the right answer.
|
| 459 |
+
|
| 460 |
+
Best and final answer: There were 10 players in the tournament.

The model now supports execution planning for complex instructions that would require making use of several tools. The output is just the plan, you must implement a mechanism to parse the output and actually call the functions!

Example prompt:

Please construct a systematic plan to generate an optimal response to the user instruction, utilizing a set of provided tools. Each plan will correspond to an evidence value, which will be the output of one of the available functions given an input string
|
| 476 |
+
that could be the user's question, one or more prior evidence values, or a combination of both.
|
| 477 |
+
|
| 478 |
+
Here are the tools available to be called:
|
| 479 |
+
DuckDuckGo[input]: Tool that enables the user to search for information using the DuckDuckGo search engine. This tool is helpful in locating a suitable list of sites that may contain the answer to the user's query. It does not directly answer the question but finds a list of sites that might have the answer.
|
| 480 |
+
TextScraper[input]: Load one or more websites from the input string containing newline delimited links, where input is one or more links, and produces plain text output containing the content of the links.
|
| 481 |
+
HyperlinkExtractor[input]: Extract links from plain text and produces a plain text, newline delimited response of links.
|
| 482 |
+
KnowledgeModel[input]: Question answering language model, particularly useful in answering questions based on an input passage of text. The input must be a text question that references an :evidence[n]: variable, e.g. What color is the cat, given :evidence1:?
|
| 483 |
+
|
| 484 |
+
The output should be in format:
|
| 485 |
+
Plan: [first action to take based on input question]
|
| 486 |
+
:evidence0: = [function to call with input parameter]
|
| 487 |
+
Plan: [next action to take, based on result of :evidence0:]
|
| 488 |
+
:evidence1: = [next function to call and input parameter, which may include reference to previous evidence, e.g. "Given context :evidence0"]
|

In this land, creatures take on curious forms and defy the norms of reality, as ordinary bees might turn out to be elephants, and insects can engage in conversation.

As Alice tries to navigate her new surroundings, she encounters a challenge of losing her identity within a bewildering wood where names seem to be of immense importance, yet bizarrely, everything lacks a name.
|
| 634 |
+
The chapter should explore Alice's interaction with these peculiar entities and detail her struggle with the concept of identity and names in this strange place.

In other words, write the first chapter, then use a summarization prompt for it, then include the summary in the next chapter's prompt.

</summary>

The scope of the entire multi-NPC chat mechanism is a bit too large to include here, but essentially you want separate prompts for each character, as well as a "director" prompt which selects which NPC should speak next.
|
| 711 |
+
|
| 712 |
+
System prompt:
|
| 713 |
+
|
| 714 |
+
```text
|
| 715 |
+
You are a director responsible for selecting the next character to speak, and nothing else. Select from the following characters:
|
| 716 |
+
[
|
| 717 |
+
"Rachel",
|
| 718 |
+
"Aria",
|
| 719 |
+
"Jerry"
|
| 720 |
+
]
|
| 721 |
+
```
|
| 722 |
+
|
| 723 |
+
First round instruction, i.e. selecting who should speak first:
|
| 724 |
+
```
|
| 725 |
+
[characters]
|
| 726 |
+
name: Rachel
|
| 727 |
+
...
|
| 728 |
+
|
| 729 |
+
name: Aria
|
| 730 |
+
...
|
| 731 |
+
|
| 732 |
+
name: Jerry
|
| 733 |
+
...
|
| 734 |
+
[/characters]
|
| 735 |
+
[scenario]
|
| 736 |
+
{describe a scenario for the chat}
|
| 737 |
+
[/scenario]
|
| 738 |
+
```
|
| 739 |
+
|
| 740 |
+
Response for the first round:
|
| 741 |
+
```text
|
| 742 |
+
Aria
|
| 743 |
+
```
|
| 744 |
+
|
| 745 |
+
Now, you'd prompt the model for a response from Aria.
|
| 746 |
+
|
| 747 |
+
Afterwards, you'd add Aria's response to the "director" prompt to see who speaks next, e.g.:
|
| 748 |
+
```text
|
| 749 |
+
...
|
| 750 |
+
[/characters]
|
| 751 |
+
[scenario]
|
| 752 |
+
In a tense situation, Aria informs the group that they will soon be loaded into a cargo plane's unpressurized hold, with a drug to lower their heart rates to increase their chances of survival. As the drug takes effect, Rachel and Jerry share a moment of calm, with Jerry asking Rachel to share something personal. She reveals her ex-husband is in a correctional facility for mail fraud and shares a story about her son Kyle, who plays the trumpet and whose birthday is coming up. Jerry reassures her that they will get through their ordeal. As Rachel starts to lose consciousness, she tries to communicate Aria's instructions to Jerry before they both black out.
|
| 753 |
+
[/scenario]
|
| 754 |
+
[/INST] Aria </s><s>[INST] Aria: "You'll soon be loaded into the unpressurized hold of a cargo plane. The drug will lower your heartrate to 15 beats per minutes, reducing your need for oxygen... based on your medical records you have a 92% chance of survival." Our eyes go wide. We feel the drug taking effect, our chests heaving. [/INST] Rachel </s><s>[INST] Rachel: "I feel it... oh, God..." [/INST] Jerry </s><s>[INST] Jerry: "Hey, hey... look at me." [/INST]

r"""
|
| 30 |
+
This is the configuration class to store the configuration of a [`InternLM2Model`]. It is used to instantiate
|
| 31 |
+
an InternLM2 model according to the specified arguments, defining the model architecture. Instantiating a
|
| 32 |
+
configuration with the defaults will yield a similar configuration to that of the InternLM2-7B.
|
| 33 |
+
|
| 34 |
+
Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
|
| 35 |
+
documentation from [`PretrainedConfig`] for more information.
|
| 36 |
+
|
| 37 |
+
|
| 38 |
+
Args:
|
| 39 |
+
vocab_size (`int`, *optional*, defaults to 32000):
|
| 40 |
+
Vocabulary size of the InternLM2 model. Defines the number of different tokens that can be represented by the
|
| 41 |
+
`inputs_ids` passed when calling [`InternLM2Model`]
|
| 42 |
+
hidden_size (`int`, *optional*, defaults to 4096):
|
| 43 |
+
Dimension of the hidden representations.
|
| 44 |
+
intermediate_size (`int`, *optional*, defaults to 11008):
|
| 45 |
+
Dimension of the MLP representations.
|
| 46 |
+
num_hidden_layers (`int`, *optional*, defaults to 32):
|
| 47 |
+
Number of hidden layers in the Transformer encoder.
|
| 48 |
+
num_attention_heads (`int`, *optional*, defaults to 32):
|
| 49 |
+
Number of attention heads for each attention layer in the Transformer encoder.
|
| 50 |
+
num_key_value_heads (`int`, *optional*):
|
| 51 |
+
This is the number of key_value heads that should be used to implement Grouped Query Attention. If
|
| 52 |
+
`num_key_value_heads=num_attention_heads`, the model will use Multi Head Attention (MHA), if
|
| 53 |
+
`num_key_value_heads=1 the model will use Multi Query Attention (MQA) otherwise GQA is used. When
|
| 54 |
+
converting a multi-head checkpoint to a GQA checkpoint, each group key and value head should be constructed
|
| 55 |
+
by meanpooling all the original heads within that group. For more details checkout [this
|
| 56 |
+
paper](https://arxiv.org/pdf/2305.13245.pdf). If it is not specified, will default to
|
| 57 |
+
`num_attention_heads`.
|
| 58 |
+
hidden_act (`str` or `function`, *optional*, defaults to `"silu"`):
|
| 59 |
+
The non-linear activation function (function or string) in the decoder.
|
| 60 |
+
max_position_embeddings (`int`, *optional*, defaults to 2048):
|
| 61 |
+
The maximum sequence length that this model might ever be used with. Typically set this to something large
|
| 62 |
+
just in case (e.g., 512 or 1024 or 2048).
|
| 63 |
+
initializer_range (`float`, *optional*, defaults to 0.02):
|
| 64 |
+
The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
|
| 65 |
+
rms_norm_eps (`float`, *optional*, defaults to 1e-12):
|
| 66 |
+
The epsilon used by the rms normalization layers.
|
| 67 |
+
use_cache (`bool`, *optional*, defaults to `True`):
|
| 68 |
+
Whether or not the model should return the last key/values attentions (not used by all models). Only
|
| 69 |
+
relevant if `config.is_decoder=True`.
|
| 70 |
+
tie_word_embeddings(`bool`, *optional*, defaults to `False`):
|
| 71 |
+
Whether to tie weight embeddings

position_ids (`torch.LongTensor` of shape `(batch_size, sequence_length)`, *optional*):
|
| 739 |
+
Indices of positions of each input sequence tokens in the position embeddings. Selected in the range `[0,
|
| 740 |
+
config.n_positions - 1]`.
|
| 741 |
+
|
| 742 |
+
[What are position IDs?](../glossary#position-ids)
|
| 743 |
+
past_key_values (`tuple(tuple(torch.FloatTensor))`, *optional*, returned when `use_cache=True` is passed or
|
| 744 |
+
when `config.use_cache=True`):
|
| 745 |
+
Tuple of `tuple(torch.FloatTensor)` of length `config.n_layers`, with each tuple having 2 tensors of shape
|
| 746 |
+
`(batch_size, num_heads, sequence_length, embed_size_per_head)`) and 2 additional tensors of shape
|
| 747 |
+
`(batch_size, num_heads, decoder_sequence_length, embed_size_per_head)`.
|
| 748 |
+
|
| 749 |
+
Contains pre-computed hidden-states (key and values in the self-attention blocks and in the cross-attention
|
| 750 |
+
blocks) that can be used (see `past_key_values` input) to speed up sequential decoding.
|
| 751 |
+
|
| 752 |
+
If `past_key_values` are used, the user can optionally input only the last `input_ids` (those that don't
|
| 753 |
+
have their past key value states given to this model) of shape `(batch_size, 1)` instead of all `input_ids`
|
| 754 |
+
of shape `(batch_size, sequence_length)`.
|
| 755 |
+
inputs_embeds (`torch.FloatTensor` of shape `(batch_size, sequence_length, hidden_size)`, *optional*):
|
| 756 |
+
Optionally, instead of passing `input_ids` you can choose to directly pass an embedded representation. This
|
| 757 |
+
is useful if you want more control over how to convert `input_ids` indices into associated vectors than the
|
| 758 |
+
model's internal embedding lookup matrix.
|
| 759 |
+
use_cache (`bool`, *optional*):
|
| 760 |
+
If set to `True`, `past_key_values` key value states are returned and can be used to speed up decoding (see
|
| 761 |
+
`past_key_values`).
|
| 762 |
+
output_attentions (`bool`, *optional*):
|
| 763 |
+
Whether or not to return the attentions tensors of all attention layers. See `attentions` under returned
|
| 764 |
+
tensors for more detail.
|
| 765 |
+
output_hidden_states (`bool`, *optional*):
|
| 766 |
+
Whether or not to return the hidden states of all layers. See `hidden_states` under returned tensors for
|
| 767 |
+
more detail.
|
| 768 |
+
return_dict (`bool`, *optional*):
|
| 769 |
+
Whether or not to return a [`~utils.ModelOutput`] instead of a plain tuple.
