# Set API key
embaas_api_key = "YOUR_API_KEY"
# or set environment variable
os.environ["EMBAAS_API_KEY"] = "YOUR_API_KEY"

Using a blob (bytes)​

from langchain.document_loaders.embaas import EmbaasBlobLoader
from langchain.document_loaders.blob_loaders import Blob

API Reference:

  • EmbaasBlobLoader from langchain.document_loaders.embaas
  • Blob from langchain.document_loaders.blob_loaders
blob_loader = EmbaasBlobLoader()
blob = Blob.from_path("example.pdf")
documents = blob_loader.load(blob)
# You can also directly create embeddings with your preferred embeddings model
blob_loader = EmbaasBlobLoader(params={"model": "e5-large-v2", "should_embed": True})
blob = Blob.from_path("example.pdf")
documents = blob_loader.load(blob)

print(documents[0]["metadata"]["embedding"])

Using a file​

from langchain.document_loaders.embaas import EmbaasLoader

API Reference:

file_loader = EmbaasLoader(file_path="example.pdf")
documents = file_loader.load()
# Disable automatic text splitting
file_loader = EmbaasLoader(file_path="example.mp3", params={"should_chunk": False})
documents = file_loader.load()
