The whole point of chat templates is to allow code +to be transferable across models, so deviating from the standard tools API means users will have to write +custom code to use tools with your model. Sometimes it's unavoidable, but often with clever templating you can +make the standard API work! + +Below, we'll list the elements of the standard API, and give tips on writing templates that will work well with it. + +#### Tool definitions + +Your template should expect that the variable `tools` will either be null (if no tools are passed), or is a list +of JSON schema dicts. Our chat template methods allow users to pass tools as either JSON schema or Python functions, but when +functions are passed, we automatically generate JSON schema and pass that to your template. As a result, the +`tools` variable that your template receives will always be a list of JSON schema. Here is +a sample tool JSON schema: + +```json +{ + "type": "function", + "function": { + "name": "multiply", + "description": "A function that multiplies two numbers", + "parameters": { + "type": "object", + "properties": { + "a": { + "type": "number", + "description": "The first number to multiply" + }, + "b": { + "type": "number", + "description": "The second number to multiply" + } + }, + "required": ["a", "b"] + } + } +} +``` + +And here is some example code for handling tools in your chat template. Remember, this is just an example for a +specific format - your model will probably need different formatting! + +```text +{%- if tools %} + {%- for tool in tools %} + {{- '' + tool['function']['name'] + '\n' }} + {%- for argument in tool['function']['parameters']['properties'] %} + {{- argument + ': ' + tool['function']['parameters']['properties'][argument]['description'] + '\n' }} + {%- endfor %} + {{- '\n' }} + {%- endif %} +{%- endif %} +``` + +The specific tokens and tool descriptions your template renders should of course be chosen to match the ones your model +was trained with. There is no requirement that your **model** understands JSON schema input, only that your template can translate +JSON schema into your model's format. For example, [Command-R](https://huggingface.co/CohereForAI/c4ai-command-r-plus-08-2024) +was trained with tools defined using Python function headers, but the Command-R tool template accepts JSON schema, +converts types internally and renders the input tools as Python headers. You can do a lot with templates! + +#### Tool calls + +Tool calls, if present, will be a list attached to a message with the "assistant" role. Note that `tool_calls` is +always a list, even though most tool-calling models only support single tool calls at a time, which means +the list will usually only have a single element. Here is a sample message dict containing a tool call: + +```json +{ + "role": "assistant", + "tool_calls": [ + { + "type": "function", + "function": { + "name": "multiply", + "arguments": { + "a": 5, + "b": 6 + } + } + } + ] +} +``` + +And a common pattern for handling them would be something like this: + +```text +{%- if message['role'] == 'assistant' and 'tool_calls' in message %} + {%- for tool_call in message['tool_calls'] %} + {{- '' + tool_call['function']['name'] + '\n' + tool_call['function']['arguments']|tojson + '\n' }} + {%- endif %} + {%- endfor %} +{%- endif %} +``` + +Again, you should render the tool call with the formatting and special tokens that your model expects. + +#### Tool responses + +Tool responses have a simple format: They are a message dict with the "tool" role, a "name" key giving the name +of the called function, and a "content" key containing the result of the tool call. Here is a sample tool response: + +```json +{ + "role": "tool", + "name": "multiply", + "content": "30" +} +``` + +You don't need to use all of the keys in the tool response. For example, if your model doesn't expect the function +name to be included in the tool response, then rendering it can be as simple as: + +```text +{%- if message['role'] == 'tool' %} + {{- "" + message['content'] + "" }} +{%- endif %} +``` + +Again, remember that the actual formatting and special tokens are model-specific - you should take a lot of care +to ensure that tokens, whitespace and everything else exactly match the format your model was trained with! \ No newline at end of file diff --git a/docs/source/en/gguf.md b/docs/source/en/gguf.md index 0c6700544ae5c2..890ca042488154 100644 --- a/docs/source/en/gguf.md +++ b/docs/source/en/gguf.md @@ -81,6 +81,7 @@ For now the supported model architectures are the architectures that have been v - Qwen2Moe - Phi3 - Bloom +- Falcon ## Example usage diff --git a/docs/source/en/how_to_hack_models.md b/docs/source/en/how_to_hack_models.md new file mode 100644 index 00000000000000..411539e104bfc2 --- /dev/null +++ b/docs/source/en/how_to_hack_models.md @@ -0,0 +1,180 @@ + + +# How to Hack Any Transformers Model + +The [🤗 Transformers](https://github.com/huggingface/transformers) library offers a collection of pre-trained models and tools for natural language processing, vision, and beyond. While these models cover a wide range of applications, you might encounter use cases that aren't supported out of the box. Customizing models can unlock new possibilities, such as adding new layers, altering architectures, or optimizing attention mechanisms. This guide will show you how to modify existing Transformers models to fit your specific needs. The great thing is, you don’t have to step away from the Transformers framework to make these changes. You can actually modify models directly in Transformers and still take advantage of features like the [Trainer API](https://huggingface.co/docs/transformers/main/en/main_classes/trainer), [PreTrainedModel](https://huggingface.co/docs/transformers/main/en/main_classes/model#transformers.PreTrainedModel), and efficient fine-tuning with tools like [PEFT](https://huggingface.co/docs/peft/index). + +In this guide, we’ll walk you through how to customize existing Transformers models to meet your requirements—without losing the benefits of the ecosystem. + +You'll learn how to: + +- Modify a model's architecture by changing its attention mechanism. +- Apply techniques like Low-Rank Adaptation (LoRA) to specific model components. + +We encourage you to contribute your own hacks and share them here with the community1 + +## Example: Modifying the Attention Mechanism in the Segment Anything Model (SAM) + +The **Segment Anything Model (SAM)** is a state-of-the-art model for image segmentation.

This approach allows you to: + +- Fine-tune fewer parameters, reducing computational overhead. +- Potentially achieve better performance by focusing on specific components. +- Experiment with different adaptation strategies in the attention mechanism. + +### Implementation + +#### **Step 1: Create a Custom Attention Class** + +Next, subclass the original `SamVisionAttention` class and modify it to have separate `q`, `k`, and `v` projections. + +```python +import torch +import torch.nn as nn +from transformers.models.sam.modeling_sam import SamVisionAttention + +class SamVisionAttentionSplit(SamVisionAttention, nn.Module): + def __init__(self, config, window_size): + super().__init__(config, window_size) + del self.qkv + # Separate q, k, v projections + self.q = nn.Linear(config.hidden_size, config.hidden_size, bias=config.qkv_bias) + self.k = nn.Linear(config.hidden_size, config.hidden_size, bias=config.qkv_bias) + self.v = nn.Linear(config.hidden_size, config.hidden_size, bias=config.qkv_bias) + self._register_load_state_dict_pre_hook(self.split_q_k_v_load_hook) + + def split_q_k_v_load_hook(self, state_dict, prefix, *args): + keys_to_delete = [] + for key in list(state_dict.keys()): + if "qkv." in key: + # Split q, k, v from the combined projection + q, k, v = state_dict[key].chunk(3, dim=0) + # Replace with individual q, k, v projections + state_dict[key.replace("qkv.", "q.")] = q + state_dict[key.replace("qkv.", "k.")] = k + state_dict[key.replace("qkv.", "v.")] = v + # Mark the old qkv key for deletion + keys_to_delete.append(key) + + # Remove old qkv keys + for key in keys_to_delete: + del state_dict[key] + + def forward(self, hidden_states: torch.Tensor, output_attentions=False) -> torch.Tensor: + batch_size, height, width, _ = hidden_states.shape + qkv_shapes = (batch_size * self.num_attention_heads, height * width, -1) + query = self.q(hidden_states).reshape((batch_size, height * width,self.num_attention_heads, -1)).permute(0,2,1,3).reshape(qkv_shapes) + key = self.k(hidden_states).reshape((batch_size, height * width,self.num_attention_heads, -1)).permute(0,2,1,3).reshape(qkv_shapes) + value = self.v(hidden_states).reshape((batch_size, height * width,self.num_attention_heads, -1)).permute(0,2,1,3).reshape(qkv_shapes) + + attn_weights = (query * self.scale) @ key.transpose(-2, -1) + + if self.use_rel_pos: + attn_weights = self.add_decomposed_rel_pos( + attn_weights, query, self.rel_pos_h, self.rel_pos_w, (height, width), (height, width) + ) + + attn_weights = torch.nn.functional.softmax(attn_weights, dtype=torch.float32, dim=-1).to(query.dtype) + attn_probs = nn.functional.dropout(attn_weights, p=self.dropout, training=self.training) + attn_output = (attn_probs @ value).reshape(batch_size, self.num_attention_heads, height, width, -1) + attn_output = attn_output.permute(0, 2, 3, 1, 4).reshape(batch_size, height, width, -1) + attn_output = self.proj(attn_output) + + if output_attentions: + outputs = (attn_output, attn_weights) + else: + outputs = (attn_output, None) + return outputs +``` + +**Explanation:** + +- **Separate Projections:** The combined `qkv` projection is removed, and separate `q`, `k`, and `v` linear layers are created. +- **Weight Loading Hook:** The `_split_qkv_load_hook` method splits the pre-trained `qkv` weights into separate `q`, `k`, and `v` weights when loading the model.
