This behaviour may be subject to change in future releases. - - -API reference -^^^^^^^^^^^^^ - -.. autoclass:: stormtrooper.TGIZeroShotClassifier - :members: - -.. autoclass:: stormtrooper.TGIFewShotClassifier - :members: diff --git a/docs/_build/html/_sources/zeroshot.rst.txt b/docs/_build/html/_sources/zeroshot.rst.txt deleted file mode 100644 index 8687d3a..0000000 --- a/docs/_build/html/_sources/zeroshot.rst.txt +++ /dev/null @@ -1,32 +0,0 @@ -Zero-shot models -================ - -In stormtrooper you can use models specifically designed and tuned for zero-shot classification. -These provide the most extensive functionality including estimating certainties/probabilities for class labels. - - -.. code-block:: python - - from stormtrooper import ZeroShotClassifier - - sample_text = "It is the Electoral College's responsibility to elect the president." - - model = ZeroShotClassifier("facebook/bart-large-mnli").fit(None, ["politics", "science", "other"]) - predictions = model.predict([sample_text]) - assert list(predictions) == ["politics"] - - model.set_output(transform="pandas") - model.transform([sample_text]) - - -+-----------+----------+---------+ -| politics | science | other | -+===========+==========+=========+ -| 0.924671 | 0.006629 | 0.0687 | -+-----------+----------+---------+ - -API reference -^^^^^^^^^^^^^ - -.. autoclass:: stormtrooper.ZeroShotClassifier - :members: diff --git a/docs/_build/html/_static/_sphinx_javascript_frameworks_compat.js b/docs/_build/html/_static/_sphinx_javascript_frameworks_compat.js deleted file mode 100644 index 8549469..0000000 --- a/docs/_build/html/_static/_sphinx_javascript_frameworks_compat.js +++ /dev/null @@ -1,134 +0,0 @@ -/* - * _sphinx_javascript_frameworks_compat.js - * ~~~~~~~~~~ - * - * Compatability shim for jQuery and underscores.js. - * - * WILL BE REMOVED IN Sphinx 6.0 - * xref RemovedInSphinx60Warning - * - */ - -/** - * select a different prefix for underscore - */ -$u = _.noConflict(); - - -/** - * small helper function to urldecode strings - * - * See https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/decodeURIComponent#Decoding_query_parameters_from_a_URL - */ -jQuery.urldecode = function(x) { - if (!x) { - return x - } - return decodeURIComponent(x.replace(/\+/g, ' ')); -}; - -/** - * small helper function to urlencode strings - */ -jQuery.urlencode = encodeURIComponent; - -/** - * This function returns the parsed url parameters of the - * current request.

Generative models#

-

stormtrooper also supports fully generative model architectures both for few-shot and zero-shot learning. -It’s worth noting that most instruct finetuned generative models are quite hefty and take a lot of resources -to run. We recommend that you exhaust all other options before you turn to generative models.

-
from stormtrooper import GenerativeZeroShotClassifier, GenerativeFewShotClassifier
-
-sample_text = "It is the Electoral College's responsibility to elect the president."
-
-labels = ["politics", "science", "other"]
-
-
-

Here’s a zero shot example:

-
model = GenerativeZeroShotClassifier("stabilityai/StableBeluga-13B").fit(None, labels)
-predictions = model.predict([sample_text])
-assert list(predictions) == ["politics"]
-
-
-

And a few shot example:

-
few_shot_examples = [
-  "Joe Biden is the president.",
-  "Liquid water was found on the moon.",
-  "Jerry likes football."
-]
-
-model = GenerativeFewShotClassifier("stabilityai/StableBeluga-13B").fit(few_shot_examples, labels)
-predictions = model.predict([sample_text])
-assert list(predictions) == ["politics"]
-
-
-
-

Getting Started#

-

stormtrooper is a lightweight Python library for zero and few-shot classification using transformer models. -All components are fully scikit-learn compatible thereby making it easier to integrate them into your scikit-learn workflows and pipelines.

-
-

Installation#

-

You can install stormtrooper from PyPI.

-
pip install stormtrooper[torch]
-
-
-

If you intend to use SetFit models as well, install stormtrooper with optional dependencies.

-
pip install stormtrooper[setfit]
-
-
-

From version 0.4.0 you can also use OpenAI models in stormtrooper.

-
pip install stormtrooper[openai]
-export OPENAI_API_KEY="sk-..."
-
-
-
-
-

Usage#

-

To get started load a model from HuggingFace Hub. -In this example I am going to use Google’s FLAN-T5.

-
from stormtrooper import Text2TextZeroShotClassifier
-
-class_labels = ["atheism/christianity", "astronomy/space"]
-example_texts = [
-    "God came down to earth to save us.",
-    "A new nebula was recently discovered in the proximity of the Oort cloud."
-]
-
-model = Text2TextZeroShotClassifier("google/flan-t5-base").fit(None, class_labels)
-predictions = model.predict(example_texts)
-
-

Inference on GPU#

-

Models in stormtrooper run on the CPU by default, but you can influence this behaviour by specifying a device when initializing a model.

-

Make sure to check whether you have a Cuda device available before trying to run inference on it.

-
-

Warning

-

Note that this does not include TGI and OpenAI models, as the models themselves run either on remote servers -or in a separate process on your computer.

-
-

-
-print(torch.cuda.is_available())

OpenAI models#

-

Stormtrooper gives you access to OpenAI’s chat models for zero and few-shot classification. -You get full control over temperature settings, system and user prompts. -In contrast to other packages, like scikit-llm, stormtrooper also uses Python’s asyncio to concurrently -interact with OpenAI’s API. This can give multiple times speedup on several tasks.

-

You can also set upper limits for number of requests and tokens per minute, so you don’t exceed your quota. -This is by default set to the limit of the payed tier on OpenAI’s API.

-

You need to install stormtrooper with optional dependencies.

-
pip install stormtrooper[openai]
-
-
-

You additionally need to set the OpenAI API key as an environment variable.

-
export OPENAI_API_KEY="sk-..."
-# Setting organization is optional
-export OPENAI_ORG="org-..."
-
-
-
from stormtrooper import OpenAIZeroShotClassifier, OpenAIFewShotClassifier
-
-sample_text = "It is the Electoral College's responsibility to elect the president."
-
-labels = ["politics", "science", "other"]
-
-
-

Here’s a zero shot example with ChatGPT 3.5:

-
model = OpenAIZeroShotClassifier("gpt-3.5-turbo").fit(None, labels)
-predictions = model.predict([sample_text])
-assert list(predictions) == ["politics"]
-
-
-

And a few shot example with ChatGPT 4:

-
few_shot_examples = [
-  "Joe Biden is the president.",
-  "Liquid water was found on the moon.",
-  "Jerry likes football."
-]
-
-model = OpenAIFewShotClassifier("gpt-4", temperature=0.2).fit(few_shot_examples, labels)
-predictions = model.predict([sample_text])
-assert list(predictions) == ["politics"]
-
-
-

Prompts have to be specified the same way as with other generative models.

-
system_prompt = """
-You're a helpful assistant.
-"""
-
-prompt = """
-Your task will be to classify a text document into one
-of the following classes: {classes}.
-Please respond with a single label that you think fits
-the document best.
-Classify the following piece of text:
-'{X}'
-"""
-
-model = OpenAIZeroShotClassifier("gpt-4", prompt=prompt, system_prompt=system_prompt)

Prompting#

-

Text2Text, Generative, and OpenAI models use a prompting approach for classification. -stormtrooper comes with default prompts, but these might not be the best for your model or use case. -stormtrooper allows you to specify custom prompts in these cases.

-
-

Templates#

-

Prompting in stormtrooper uses a templating approach, where the .format() method is called on prompts to -insert labels and data.

-

You can specify both user and system prompts for Generative and OpenAI models:

-
system_prompt = """
-You are a classification model that is really good at following
-instructions and produces brief answers
-that users can use as data right away.
-Please follow the user's instructions as precisely as you can.
-"""
-
-user_prompt = """
-Your task will be to classify a text document into one
-of the following classes: {classes}.
-Please respond with a single label that you think fits
-the document best.
-Classify the following piece of text:
-'{X}'
-"""
-
-model = GenerativeZeroShotClassifier("stabilityai/StableBeluga-13B", prompt=prompt, system_prompt=system_prompt)
-
-
-

X represents the current text in question, while classes represents the classes learned from the data.

-

A few-shot prompt for let’s say a T5 model looks as follows:

-
fewshot_prompt = """
-I will give you a piece of text. Please classify it
-as one of these classes: {classes}. Please only respond
-with the class label in the same format as provided.
-Here are some examples of texts labelled by experts.
-{examples}
-Label this piece of text:
-'{X}'
-"""
-
-
-

You can at any stage emit any of the template variables from your prompts if you want to operate with definitions for example.

SetFit models#

-

You can use SetFit in stormtrooper for training efficient zero and few-shot learning models from sentence transformers.

-

SetFit uses a prompt-free approach, needs way smaller models, and is thus faster to train, and more employable in high-performance settings for inference.

-https://raw.githubusercontent.com/huggingface/setfit/main/assets/setfit.png -

Since this requires the setfit package we recommend you install stormtrooper with its optional dependencies.

-
pip install stormtrooper[setfit]
-
-
-
from stormtrooper import SetFitZeroShotClassifier, SetFitFewShotClassifier
-
-sample_text = "It is the Electoral College's responsibility to elect the president."
-
-labels = ["politics", "science", "other"]
-
-
-

Here’s a zero shot example:

-
model = SetFitZeroShotClassifier().fit(None, labels)
-predictions = model.predict([sample_text])
-assert list(predictions) == ["politics"]
-
-
-

And a few shot example:

-
few_shot_examples = [
-  "Joe Biden is the president.",
-  "Liquid water was found on the moon.",
-  "Jerry likes football."
-]
-
-model = SetFitFewShotClassifier().fit(few_shot_examples, labels)
-predictions = model.predict([sample_text])
-assert list(predictions) == ["politics"]
-
-

Text2Text models#

-

You can easily employ text2text models for zero and few-shot classification. -By default FLAN-T5 base is used.

-
from stormtrooper import Text2TextZeroShotClassifier, Text2TextFewShotClassifier
-
-sample_text = "It is the Electoral College's responsibility to elect the president."
-
-labels = ["politics", "science", "other"]
-
-

Text Generation Inference#

-

Text Generation Inference is a relatively new tool developed by Hugging Face for blazing fast deployment of generative and seq2seq models -for inference. -TGI provides numerous benefits over just running models in Transformers, including more efficient transformer layers, quantization, -and the ability to run LLM inference on a separate computer from where the machine learning pipeline is run.

-

stormtrooper comes with built-in support for connecting to a running instance of the TGI API and is the recommended solution -for production-ready pipelines, especially if you have access to CUDA GPUs and you are using a model that is natively supported in TGI. -stormtrooper also uses async requests for interacting with the TGI instance, as such inference speed is the only bottleneck in the pipeline.

-https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/TGI.png -
-

Getting Started#

-

We recommend that you follow the guide provided in HuggingFace’s text-generation-inference documentation

-

In this tutorial I will demonstrate how to spin up StableBeluga-13b with TGI and then interface it from within stormtrooper.

-

By far the fastest way to get started is to start TGI in a Docker container. We will use all GPUs on the machine and use port 8080 on localhost, -which is the default in stormtrooper.

-
-

Note

-

You need to install NVIDIA’s Container Toolkit and CUDA drivers to be able to use GPU’s in a Docker container.

-
-
docker run --gpus all --shm-size 1g -p 8080:80 \
-  -v $PWD/huggingface_data:/data ghcr.io/huggingface/text-generation-inference:1.0.3 \
-  --model-id "stabilityai/StableBeluga-13B"
-
-
-

Then you can use TGI in stormtrooper as any other classification model.

-
from stormtrooper import TGIZeroShotClassifier, TGIFewShotClassifier
-
-sample_text = "It is the Electoral College's responsibility to elect the president."
-
-labels = ["politics", "science", "other"]
-
-
-model = TGIZeroShotClassifier().fit(None, labels)
-predictions = model.predict([sample_text])
-assert list(predictions) == ["politics"]
-
-
-
-
-

Gotchas#

-

TGI has almost the same behaviour as any other module in stormtrooper but the interface differs subtlely, but crucially in a handful of instances.

-
    -

  1. You can use both text2text and purely generative models with TGI, but stormtrooper is entirely agnostic to which model is being run. As such you have to accomodate for these differences in your prompts. The default prompt format is suited for StableBeluga, but may be inappropriate for Google’s FLAN-T5.

    2. -

  2. Most models in stormtrooper just slice the list of tokens in the prompt when it is too long. In contrast, with TGI you have to pay special attention to the length of your prompts. If the prompt is too long with the data infused, a warning will be raised and None will be returned. This behaviour may be subject to change in future releases.

Zero-shot models#

-

In stormtrooper you can use models specifically designed and tuned for zero-shot classification. -These provide the most extensive functionality including estimating certainties/probabilities for class labels.

-
from stormtrooper import ZeroShotClassifier
-
-sample_text = "It is the Electoral College's responsibility to elect the president."
-
-model = ZeroShotClassifier("facebook/bart-large-mnli").fit(None, ["politics", "science", "other"])
-predictions = model.predict([sample_text])
-assert list(predictions) == ["politics"]
-
-model.set_output(transform="pandas")
-model.transform([sample_text])
