Experiment with different indices, models, and more.

class llama_index.playground.base.Playground(indices: ~typing.List[~llama_index.indices.base.BaseGPTIndex], retriever_modes: ~typing.Dict[~typing.Type[~llama_index.indices.base.BaseGPTIndex], ~typing.List[str]] = {<class 'llama_index.indices.tree.base.GPTTreeIndex'>: ['select_leaf', 'select_leaf_embedding', 'all_leaf', 'root'], <class 'llama_index.indices.list.base.GPTListIndex'>: ['default', 'embedding', 'llm'], <class 'llama_index.indices.vector_store.base.GPTVectorStoreIndex'>: ['default']})

Experiment with indices, models, embeddings, retriever_modes, and more.

compare(query_text: str, to_pandas: Optional[bool] = True) → Union[DataFrame, List[Dict[str, Any]]]

Compare index outputs on an input query.

参数

• query_text (str) -- Query to run all indices on.

• to_pandas (Optional[bool]) -- Return results in a pandas dataframe. True by default.

返回

The output of each index along with other data, such as the time it took to compute. Results are stored in a Pandas Dataframe or a list of Dicts.
