The easiest way to get started is to follow this notebook

​
1. Configure API Keys

Evals use OpenAI, so you need to configure your OpenAI API key. If you wish to view the results on Athina Develop, and maintain a historical record of prompts and experiments you run during your development workflow, then you also need an Athina API Key. 
from athina.keys import AthinaApiKey, OpenAiApiKey

OpenAiApiKey.set_key(os.getenv('OPENAI_API_KEY'))
AthinaApiKey.set_key(os.getenv('ATHINA_API_KEY')) # optional

​
2. Load your dataset

Loading a dataset is quite straightforward - we support JSON and CSV formats. 
from athina.loaders import Loader

# Load the data from JSON, Athina or Dictionary
dataset = Loader().load_json(json_file)

​
3. Run an eval on a dataset

Running evals on a batch of datapoints is the most effective way to rapidly iterate as you’re developing your model. 
from athina.evals import ContextContainsEnoughInformation

# Run the ContextContainsEnoughInformation evaluator on the dataset
ContextContainsEnoughInformation(
    model="gpt-4-1106-preview",
    max_parallel_evals=5, # optional, speeds up evals
).run_batch(dataset).to_df()
Your results will be printed out as a dataframe that looks like this.

​
How do I know which fields I need in my dataset?

For the RAG Evals, we need 3 fields: query, context, and response.For these evals, you should use the RagLoader to load your data. This will ensure the data is in the right format for evals.
Every evaluator has a REQUIRED_ARGS property that defines the parameters it expects. If you pass the wrong parameters, the evaluator will raise a ValueError telling you what params you are missing. For example:, the Faithfulness evaluator expects response and context fields.

​
Run an eval on a single datapoint

Running an eval on a single datapoint is very simple. This might be useful if you are trying to run the eval immediately after inference. 
# Run the answer relevance evaluator
# Checks if the LLM response answers the user query sufficiently
DoesResponseAnswerQuery().run(query=query, response=response)
Here’s a notebook you can use to get started.
