/Users/nielsrogge/Documents/python_projecten/transformers/docs/source/en/tasks/language_modeling.md | https://huggingface.co/docs/transformers/en/tasks/language_modeling/#inference | .md | Great, now that you've finetuned a model, you can use it for inference!
Come up with a prompt you'd like to generate text from:
```py
>>> prompt = "Somatic hypermutation allows the immune system to"
```
The simplest way to try out your finetuned model for inference is to use it in a [`pipeline`]. Instantiate a `pipeline` for text generation with your model, and pass your text to it:
```py
>>> from transformers import pipeline | 99_5_0 |
/Users/nielsrogge/Documents/python_projecten/transformers/docs/source/en/tasks/language_modeling.md | https://huggingface.co/docs/transformers/en/tasks/language_modeling/#inference | .md | >>> generator = pipeline("text-generation", model="username/my_awesome_eli5_clm-model")
>>> generator(prompt)
[{'generated_text': "Somatic hypermutation allows the immune system to be able to effectively reverse the damage caused by an infection.\n\n\nThe damage caused by an infection is caused by the immune system's ability to perform its own self-correcting tasks."}]
```

Large Language Models such as Falcon, LLaMA, etc. are pretrained transformer models initially trained to predict the
next token given some input text. They typically have billions of parameters and have been trained on trillions of
tokens for an extended period of time. As a result, these models become quite powerful and versatile, and you can use
them to solve multiple NLP tasks out of the box by instructing the models with natural language prompts. | 100_1_0 |

Designing such prompts to ensure the optimal output is often called "prompt engineering". Prompt engineering is an
iterative process that requires a fair amount of experimentation. Natural languages are much more flexible and expressive
than programming languages, however, they can also introduce some ambiguity. At the same time, prompts in natural language | 100_1_1 |

At the same time, prompts in natural language
are quite sensitive to changes. Even minor modifications in prompts can lead to wildly different outputs.
While there is no exact recipe for creating prompts to match all cases, researchers have worked out a number of best
practices that help to achieve optimal results more consistently. | 100_1_2 |

Prompt engineering is only a part of the LLM output optimization process. Another essential component is choosing the
optimal text generation strategy. You can customize how your LLM selects each of the subsequent tokens when generating
the text without modifying any of the trainable parameters. By tweaking the text generation parameters, you can reduce | 100_1_4 |

By tweaking the text generation parameters, you can reduce
repetition in the generated text and make it more coherent and human-sounding.
Text generation strategies and parameters are out of scope for this guide, but you can learn more about these topics in

/Users/nielsrogge/Documents/python_projecten/transformers/docs/source/en/tasks/prompting.md | https://huggingface.co/docs/transformers/en/tasks/prompting/#types-of-models | .md | The majority of modern LLMs are decoder-only transformers. Some examples include: [LLaMA](../model_doc/llama),
[Llama2](../model_doc/llama2), [Falcon](../model_doc/falcon), [GPT2](../model_doc/gpt2). However, you may encounter
encoder-decoder transformer LLMs as well, for instance, [Flan-T5](../model_doc/flan-t5) and [BART](../model_doc/bart).

/Users/nielsrogge/Documents/python_projecten/transformers/docs/source/en/tasks/prompting.md | https://huggingface.co/docs/transformers/en/tasks/prompting/#types-of-models | .md | Encoder-decoder-style models are typically used in generative tasks where the output **heavily** relies on the input, for
example, in translation and summarization. The decoder-only models are used for all other types of generative tasks.
When using a pipeline to generate text with an LLM, it's important to know what type of LLM you are using, because
they use different pipelines.
Run inference with decoder-only models with the `text-generation` pipeline:
```python | 100_2_1 |
/Users/nielsrogge/Documents/python_projecten/transformers/docs/source/en/tasks/prompting.md | https://huggingface.co/docs/transformers/en/tasks/prompting/#types-of-models | .md | they use different pipelines.
Run inference with decoder-only models with the `text-generation` pipeline:
```python
>>> from transformers import pipeline
>>> import torch | 100_2_2 |
/Users/nielsrogge/Documents/python_projecten/transformers/docs/source/en/tasks/prompting.md | https://huggingface.co/docs/transformers/en/tasks/prompting/#types-of-models | .md | >>> torch.manual_seed(0) # doctest: +IGNORE_RESULT
>>> generator = pipeline('text-generation', model = 'openai-community/gpt2')
>>> prompt = "Hello, I'm a language model" | 100_2_3 |
/Users/nielsrogge/Documents/python_projecten/transformers/docs/source/en/tasks/prompting.md | https://huggingface.co/docs/transformers/en/tasks/prompting/#types-of-models | .md | >>> generator(prompt, max_length = 30)
[{'generated_text': "Hello, I'm a language model programmer so you can use some of my stuff. But you also need some sort of a C program to run."}]
```
To run inference with an encoder-decoder, use the `text2text-generation` pipeline:
```python
>>> text2text_generator = pipeline("text2text-generation", model = 'google/flan-t5-base')
>>> prompt = "Translate from English to French: I'm very happy to see you" | 100_2_4 |

/Users/nielsrogge/Documents/python_projecten/transformers/docs/source/en/tasks/prompting.md | https://huggingface.co/docs/transformers/en/tasks/prompting/#base-vs-instructchat-models | .md | Most of the recent LLM checkpoints available on 🤗 Hub come in two versions: base and instruct (or chat). For example,
[`tiiuae/falcon-7b`](https://huggingface.co/tiiuae/falcon-7b) and [`tiiuae/falcon-7b-instruct`](https://huggingface.co/tiiuae/falcon-7b-instruct).
Base models are excellent at completing the text when given an initial prompt, however, they are not ideal for NLP tasks
where they need to follow instructions, or for conversational use. This is where the instruct (chat) versions come in. | 100_3_0 |
/Users/nielsrogge/Documents/python_projecten/transformers/docs/source/en/tasks/prompting.md | https://huggingface.co/docs/transformers/en/tasks/prompting/#base-vs-instructchat-models | .md | where they need to follow instructions, or for conversational use. This is where the instruct (chat) versions come in.
These checkpoints are the result of further fine-tuning of the pre-trained base versions on instructions and conversational data.
This additional fine-tuning makes them a better choice for many NLP tasks.
Let's illustrate some simple prompts that you can use with [`tiiuae/falcon-7b-instruct`](https://huggingface.co/tiiuae/falcon-7b-instruct)
to solve some common NLP tasks. | 100_3_1 |
/Users/nielsrogge/Documents/python_projecten/transformers/docs/source/en/tasks/prompting.md | https://huggingface.co/docs/transformers/en/tasks/prompting/#nlp-tasks | .md | First, let's set up the environment:
```bash
pip install -q transformers accelerate
```
Next, let's load the model with the appropriate pipeline (`"text-generation"`):
```python
>>> from transformers import pipeline, AutoTokenizer
>>> import torch
>>> torch.manual_seed(0) # doctest: +IGNORE_RESULT
>>> model = "tiiuae/falcon-7b-instruct" | 100_4_0 |
/Users/nielsrogge/Documents/python_projecten/transformers/docs/source/en/tasks/prompting.md | https://huggingface.co/docs/transformers/en/tasks/prompting/#nlp-tasks | .md | >>> tokenizer = AutoTokenizer.from_pretrained(model)
>>> pipe = pipeline(
... "text-generation",
... model=model,
... tokenizer=tokenizer,
... torch_dtype=torch.bfloat16,
... device_map="auto",
... )
```
<Tip>
Note that Falcon models were trained using the `bfloat16` datatype, so we recommend you use the same. This requires a recent
version of CUDA and works best on modern cards.

/Users/nielsrogge/Documents/python_projecten/transformers/docs/source/en/tasks/prompting.md | https://huggingface.co/docs/transformers/en/tasks/prompting/#nlp-tasks | .md | version of CUDA and works best on modern cards.
</Tip>
Now that we have the model loaded via the pipeline, let's explore how you can use prompts to solve NLP tasks. | 100_4_2 |
/Users/nielsrogge/Documents/python_projecten/transformers/docs/source/en/tasks/prompting.md | https://huggingface.co/docs/transformers/en/tasks/prompting/#text-classification | .md | One of the most common forms of text classification is sentiment analysis, which assigns a label like "positive", "negative",
or "neutral" to a sequence of text. Let's write a prompt that instructs the model to classify a given text (a movie review).
We'll start by giving the instruction, and then specifying the text to classify. Note that instead of leaving it at that, we're
also adding the beginning of the response - `"Sentiment: "`:
```python
>>> torch.manual_seed(0) # doctest: +IGNORE_RESULT | 100_5_0 |
/Users/nielsrogge/Documents/python_projecten/transformers/docs/source/en/tasks/prompting.md | https://huggingface.co/docs/transformers/en/tasks/prompting/#text-classification | .md | also adding the beginning of the response - `"Sentiment: "`:
```python
>>> torch.manual_seed(0) # doctest: +IGNORE_RESULT
>>> prompt = """Classify the text into neutral, negative or positive.
... Text: This movie is definitely one of my favorite movies of its kind. The interaction between respectable and morally strong characters is an ode to chivalry and the honor code amongst thieves and policemen.
... Sentiment:

/Users/nielsrogge/Documents/python_projecten/transformers/docs/source/en/tasks/prompting.md | https://huggingface.co/docs/transformers/en/tasks/prompting/#text-classification | .md | >>> sequences = pipe(
... prompt,
... max_new_tokens=10,
... ) | 100_5_2 |
/Users/nielsrogge/Documents/python_projecten/transformers/docs/source/en/tasks/prompting.md | https://huggingface.co/docs/transformers/en/tasks/prompting/#text-classification | .md | >>> for seq in sequences:
... print(f"Result: {seq['generated_text']}")
Result: Classify the text into neutral, negative or positive.
Text: This movie is definitely one of my favorite movies of its kind. The interaction between respectable and morally strong characters is an ode to chivalry and the honor code amongst thieves and policemen.
Sentiment:
Positive
```
As a result, the output contains a classification label from the list we have provided in the instructions, and it is a correct one! | 100_5_3 |
/Users/nielsrogge/Documents/python_projecten/transformers/docs/source/en/tasks/prompting.md | https://huggingface.co/docs/transformers/en/tasks/prompting/#text-classification | .md | <Tip>
You may notice that in addition to the prompt, we pass a `max_new_tokens` parameter. It controls the number of tokens the
model shall generate, and it is one of the many text generation parameters that you can learn about
in [Text generation strategies](../generation_strategies) guide.
</Tip> | 100_5_4 |
/Users/nielsrogge/Documents/python_projecten/transformers/docs/source/en/tasks/prompting.md | https://huggingface.co/docs/transformers/en/tasks/prompting/#named-entity-recognition | .md | Named Entity Recognition (NER) is a task of finding named entities in a piece of text, such as a person, location, or organization.
Let's modify the instructions in the prompt to make the LLM perform this task. Here, let's also set `return_full_text = False`
so that output doesn't contain the prompt:
```python
>>> torch.manual_seed(1) # doctest: +IGNORE_RESULT
>>> prompt = """Return a list of named entities in the text. | 100_6_0 |
/Users/nielsrogge/Documents/python_projecten/transformers/docs/source/en/tasks/prompting.md | https://huggingface.co/docs/transformers/en/tasks/prompting/#named-entity-recognition | .md | ```python
>>> torch.manual_seed(1) # doctest: +IGNORE_RESULT
>>> prompt = """Return a list of named entities in the text.
... Text: The Golden State Warriors are an American professional basketball team based in San Francisco.
... Named entities:
... """ | 100_6_1 |
/Users/nielsrogge/Documents/python_projecten/transformers/docs/source/en/tasks/prompting.md | https://huggingface.co/docs/transformers/en/tasks/prompting/#named-entity-recognition | .md | >>> sequences = pipe(
... prompt,
... max_new_tokens=15,
... return_full_text = False,
... )
>>> for seq in sequences:
... print(f"{seq['generated_text']}")
- Golden State Warriors
- San Francisco
```
As you can see, the model correctly identified two named entities from the given text. | 100_6_2 |
/Users/nielsrogge/Documents/python_projecten/transformers/docs/source/en/tasks/prompting.md | https://huggingface.co/docs/transformers/en/tasks/prompting/#translation | .md | Another task LLMs can perform is translation. You can choose to use encoder-decoder models for this task, however, here,
for the simplicity of the examples, we'll keep using Falcon-7b-instruct, which does a decent job. Once again, here's how
you can write a basic prompt to instruct a model to translate a piece of text from English to Italian:
```python
>>> torch.manual_seed(2) # doctest: +IGNORE_RESULT
>>> prompt = """Translate the English text to Italian. | 100_7_0 |
/Users/nielsrogge/Documents/python_projecten/transformers/docs/source/en/tasks/prompting.md | https://huggingface.co/docs/transformers/en/tasks/prompting/#translation | .md | ```python
>>> torch.manual_seed(2) # doctest: +IGNORE_RESULT
>>> prompt = """Translate the English text to Italian.
... Text: Sometimes, I've believed as many as six impossible things before breakfast.
... Translation:

/Users/nielsrogge/Documents/python_projecten/transformers/docs/source/en/tasks/prompting.md | https://huggingface.co/docs/transformers/en/tasks/prompting/#translation | .md | >>> sequences = pipe(
... prompt,
... max_new_tokens=20,
... do_sample=True,
... top_k=10,
... return_full_text = False,
... )
>>> for seq in sequences:
... print(f"{seq['generated_text']}")
A volte, ho creduto a sei impossibili cose prima di colazione.
```
Here we've added a `do_sample=True` and `top_k=10` to allow the model to be a bit more flexible when generating output. | 100_7_2 |
/Users/nielsrogge/Documents/python_projecten/transformers/docs/source/en/tasks/prompting.md | https://huggingface.co/docs/transformers/en/tasks/prompting/#text-summarization | .md | Similar to the translation, text summarization is another generative task where the output **heavily** relies on the input,
and encoder-decoder models can be a better choice. However, decoder-style models can be used for this task as well.
Previously, we have placed the instructions at the very beginning of the prompt. However, the very end of the prompt can
also be a suitable location for instructions. Typically, it's better to place the instruction on one of the extreme ends.

/Users/nielsrogge/Documents/python_projecten/transformers/docs/source/en/tasks/prompting.md | https://huggingface.co/docs/transformers/en/tasks/prompting/#reasoning | .md | Reasoning is one of the most difficult tasks for LLMs, and achieving good results often requires applying advanced prompting techniques, like
[Chain-of-thought](#chain-of-thought).
Let's try if we can make a model reason about a simple arithmetics task with a basic prompt:
```python
>>> torch.manual_seed(5) # doctest: +IGNORE_RESULT
>>> prompt = """There are 5 groups of students in the class. Each group has 4 students. How many students are there in the class?""" | 100_10_0 |

... print(f"Result: {seq['generated_text']}")
Result:
There are a total of 5 groups, so there are 5 x 4=20 students in the class.
```
Correct! Let's increase the complexity a little and see if we can still get away with a basic prompt:
```python
>>> torch.manual_seed(6) # doctest: +IGNORE_RESULT
>>> prompt = """I baked 15 muffins. I ate 2 muffins and gave 5 muffins to a neighbor. My partner then bought 6 more muffins and ate 2. How many muffins do we now have?""" | 100_10_2 |

... print(f"Result: {seq['generated_text']}")
Result:
The total number of muffins now is 21
```
This is a wrong answer, it should be 12. In this case, this can be due to the prompt being too basic, or due to the choice
of model, after all we've picked the smallest version of Falcon. Reasoning is difficult for models of all sizes, but larger
models are likely to perform better. | 100_10_4 |

* Put the instructions at the beginning of the prompt, or at the very end. When working with large context, models apply various optimizations to prevent Attention complexity from scaling quadratically. This may make a model more attentive to the beginning or end of a prompt than the middle.
* Clearly separate instructions from the text they apply to - more on this in the next section. | 100_11_1 |

* Be specific and descriptive about the task and the desired outcome - its format, length, style, language, etc.
* Avoid ambiguous descriptions and instructions.

instructions and context, but no examples with solutions. LLMs that have been fine-tuned on instruction datasets, generally
perform well on such "zero-shot" tasks. However, you may find that your task has more complexity or nuance, and, perhaps,
you have some requirements for the output that the model doesn't catch on just from the instructions. In this case, you can | 100_12_0 |

In this case, you can
try the technique called few-shot prompting.
In few-shot prompting, we provide examples in the prompt giving the model more context to improve the performance.
The examples condition the model to generate the output following the patterns in the examples.

- Few-shot prompting requires creating lengthy prompts. Prompts with large number of tokens can increase computation and latency. There's also a limit to the length of the prompts.
- Sometimes when given a number of examples, models can learn patterns that you didn't intend them to learn, e.g. that the third movie review is always negative. | 100_12_6 |

the results on complex reasoning tasks.
There are two ways of steering a model to producing the reasoning steps:
- few-shot prompting by illustrating examples with detailed answers to questions, showing the model how to work through a problem. | 100_13_0 |
/Users/nielsrogge/Documents/python_projecten/transformers/docs/source/en/tasks/prompting.md | https://huggingface.co/docs/transformers/en/tasks/prompting/#chain-of-thought | .md | - by instructing the model to reason by adding phrases like "Let's think step by step" or "Take a deep breath and work through the problem step by step."
If we apply the CoT technique to the muffins example from the [reasoning section](#reasoning) and use a larger model,
such as (`tiiuae/falcon-180B-chat`) which you can play with in the [HuggingChat](https://huggingface.co/chat/),
we'll get a significant improvement on the reasoning result:

would work better for your case. Here are some scenarios when fine-tuning a smaller model may be a preferred option:
- Your domain is wildly different from what LLMs were pre-trained on and extensive prompt optimization did not yield sufficient results.
- You need your model to work well in a low-resource language. | 100_14_0 |

- You need the model to be trained on sensitive data that is under strict regulations.
- You have to use a small model due to cost, privacy, infrastructure or other limitations.
In all of the above examples, you will need to make sure that you either already have or can easily obtain a large enough
domain-specific dataset at a reasonable cost to fine-tune a model. You will also need to have enough time and resources
to fine-tune a model. | 100_14_1 |

This has many use cases, including image similarity and image retrieval. Moreover, most computer vision models can be used for image feature extraction, where one can remove the task-specific head (image classification, object detection etc) and get the features. These features are very useful on a higher level: edge detection, corner detection and so on. They may also contain information about the real | 101_1_1 |

Let's see the pipeline in action. First, initialize the pipeline. If you don't pass any model to it, the pipeline will be automatically initialized with [google/vit-base-patch16-224](google/vit-base-patch16-224). If you'd like to calculate similarity, set `pool` to True.
```python
import torch
from transformers import pipeline
from accelerate.test_utils.testing import get_backend | 101_2_2 |
/Users/nielsrogge/Documents/python_projecten/transformers/docs/source/en/tasks/image_feature_extraction.md | https://huggingface.co/docs/transformers/en/tasks/image_feature_extraction/#image-similarity-using-image-feature-extraction-pipeline | .md | ```python
import torch
from transformers import pipeline
from accelerate.test_utils.testing import get_backend
# automatically detects the underlying device type (CUDA, CPU, XPU, MPS, etc.)
DEVICE, _, _ = get_backend()
pipe = pipeline(task="image-feature-extraction", model_name="google/vit-base-patch16-384", device=DEVICE, pool=True)
```
To infer with `pipe` pass both images to it.
```python
outputs = pipe([image_real, image_gen])
```
The output contains pooled embeddings of those two images. | 101_2_3 |
/Users/nielsrogge/Documents/python_projecten/transformers/docs/source/en/tasks/image_feature_extraction.md | https://huggingface.co/docs/transformers/en/tasks/image_feature_extraction/#image-similarity-using-image-feature-extraction-pipeline | .md | ```python
outputs = pipe([image_real, image_gen])
```
The output contains pooled embeddings of those two images.
```python
# get the length of a single output
print(len(outputs[0][0]))
# show outputs
print(outputs) | 101_2_4 |
/Users/nielsrogge/Documents/python_projecten/transformers/docs/source/en/tasks/image_feature_extraction.md | https://huggingface.co/docs/transformers/en/tasks/image_feature_extraction/#image-similarity-using-image-feature-extraction-pipeline | .md | # 768

```
To get the similarity score, we need to pass them to a similarity function.
```python
from torch.nn.functional import cosine_similarity
similarity_score = cosine_similarity(torch.Tensor(outputs[0]),
torch.Tensor(outputs[1]), dim=1)
print(similarity_score) | 101_2_5 |

```
If you want to get the last hidden states before pooling, avoid passing any value for the `pool` parameter, as it is set to `False`by default. These hidden states are useful for training new classifiers or models based on the features from the model.
```python
pipe = pipeline(task="image-feature-extraction", model_name="google/vit-base-patch16-224", device=DEVICE)
outputs = pipe(image_real)
``` | 101_2_6 |

```
Since the outputs are unpooled, we get the last hidden states where the first dimension is the batch size, and the last two are the embedding shape.
```python
import numpy as np
print(np.array(outputs).shape)
# (1, 197, 768)
``` | 101_2_7 |
/Users/nielsrogge/Documents/python_projecten/transformers/docs/source/en/tasks/image_feature_extraction.md | https://huggingface.co/docs/transformers/en/tasks/image_feature_extraction/#getting-features-and-similarities-using-automodel | .md | We can also use `AutoModel`class of transformers to get the features. `AutoModel` loads any transformers model with no task-specific head, and we can use this to get the features.
```python
from transformers import AutoImageProcessor, AutoModel | 101_3_0 |
/Users/nielsrogge/Documents/python_projecten/transformers/docs/source/en/tasks/image_feature_extraction.md | https://huggingface.co/docs/transformers/en/tasks/image_feature_extraction/#getting-features-and-similarities-using-automodel | .md | processor = AutoImageProcessor.from_pretrained("google/vit-base-patch16-224")
model = AutoModel.from_pretrained("google/vit-base-patch16-224").to(DEVICE)
```
Let's write a simple function for inference. We will pass the inputs to the `processor` first and pass its outputs to the `model`.
```python
def infer(image):
inputs = processor(image, return_tensors="pt").to(DEVICE)
outputs = model(**inputs)
return outputs.pooler_output
``` | 101_3_1 |
/Users/nielsrogge/Documents/python_projecten/transformers/docs/source/en/tasks/image_feature_extraction.md | https://huggingface.co/docs/transformers/en/tasks/image_feature_extraction/#getting-features-and-similarities-using-automodel | .md | inputs = processor(image, return_tensors="pt").to(DEVICE)
outputs = model(**inputs)
return outputs.pooler_output
```
We can pass the images directly to this function and get the embeddings.
```python
embed_real = infer(image_real)
embed_gen = infer(image_gen)
```
We can get the similarity again over the embeddings.
```python
from torch.nn.functional import cosine_similarity | 101_3_2 |
