databonsai is a Python library that uses LLMs to perform data cleaning tasks.
pip install databonsai
Store your API keys on an .env file in the root of your project, or specify it as an argument when initializing the provider.
OPENAI_API_KEY=xxx # if you use OpenAiProvider
ANTHROPIC_API_KEY=xxx # If you use AnthropicProvider
Setup the LLM provider and categories (as a dictionary.
from databonsai.categorize import MultiCategorizer, BaseCategorizer
from databonsai.llm_providers import OpenAIProvider, AnthropicProvider
provider = OpenAIProvider() # Or AnthropicProvider(). Highly recommend using Haiku, which is the default AnthropicProvider() model, as it is cheap and effective for these tasks
categories = {
"Weather": "Insights and remarks about weather conditions.",
"Sports": "Observations and comments on sports events.",
"Politics": "Political events related to governments, nations, or geopolitical issues.",
"Celebrities": "Celebrity sightings and gossip",
"Others": "Comments do not fit into any of the above categories",
"Anomaly": "Data that does not look like comments or natural language",
}
few_shot_examples = [
{"example": "Big stormy skies over city", "response": "Weather"},
{"example": "The team won the championship", "response": "Sports"},
{"example": "I saw a famous rapper at the mall", "response": "Celebrities"},
]
Categorize your data:
categorizer = BaseCategorizer(
categories=categories,
llm_provider=provider,
examples = few_shot_examples,
#strict = False # Default true, set to False to allow for categories not in the provided dict
)
category = categorizer.categorize("It's been raining outside all day")
print(category)
Output:
Weather
Use categorize_batch to categorize a batch. This saves tokens as it only sends the schema and few shot examples once! (Works best for better models. Ideally, use at least 3 few shot examples.)
categories = categorizer.categorize_batch([
"Massive Blizzard Hits the Northeast, Thousands Without Power",
"Local High School Basketball Team Wins State Championship After Dramatic Final",
"Celebrated Actor Launches New Environmental Awareness Campaign",
])
print(categories)
Output:
['Weather', 'Sports', 'Celebrities']
If you have a pandas dataframe or list, use apply_to_column_autobatch
Batching data for LLM api calls saves tokens by not sending the prompt for every row. However, too large a batch size / complex tasks can lead to errors. Naturally, the better the LLM model, the larger the batch size you can use.
This batching is handled adaptively (i.e., it will increase the batch size if the response is valid and reduce it if it's not, with a decay factor)
Other features:
Retry Logic:
from databonsai.utils import apply_to_column_batch, apply_to_column, apply_to_column_autobatch
import pandas as pd
headlines = [
"Massive Blizzard Hits the Northeast, Thousands Without Power",
"Local High School Basketball Team Wins State Championship After Dramatic Final",
"Celebrated Actor Launches New Environmental Awareness Campaign",
"President Announces Comprehensive Plan to Combat Cybersecurity Threats",
"Tech Giant Unveils Revolutionary Quantum Computer",
"Tropical Storm Alina Strengthens to Hurricane as It Approaches the Coast",
"Olympic Gold Medalist Announces Retirement, Plans Coaching Career",
"Film Industry Legends Team Up for Blockbuster Biopic",
"Government Proposes Sweeping Reforms in Public Health Sector",
"Startup Develops App That Predicts Traffic Patterns Using AI",
]
df = pd.DataFrame(headlines, columns=["Headline"])
df["Category"] = None # Initialize it if it doesn't exist, as we modify it in place
success_idx = apply_to_column_autobatch( df["Headline"], df["Category"], categorizer.categorize_batch, batch_size=3, start_idx=0)
There are many more options available for autobatch, such as setting a max_retries, decay factor, and more. Check Utils for more details
If it fails midway (even after exponential backoff), you can resume from the last successful index + 1.
success_idx = apply_to_column_autobatch( df["Headline"], df["Category"], categorizer.categorize_batch, batch_size=10, start_idx=success_idx+1)
This also works for regular python lists.
Note that the better the LLM model, the greater the batch_size you can use (depending on the length of your inputs). If you're getting errors, reduce the batch_size, or use a better LLM model.
To use it with batching, but with a fixed batch size:
success_idx = apply_to_column_batch( df["Headline"], df["Category"], categorizer.categorize_batch, batch_size=3, start_idx=0)
To use it without batching:
success_idx = apply_to_column( df["Headline"], df["Category"], categorizer.categorize)
print(categorizer.system_message)
print(categorizer.system_message_batch)
Token usage is recorded for OpenAI and Anthropic. Use these to estimate your costs!
