Setup
Credentials
Sign up for Mathpix and create an API key to set the MATHPIX_API_KEY variables in your environment
import getpass
import os
if "MATHPIX_API_KEY" not in os.environ:
os.environ["MATHPIX_API_KEY"] = getpass.getpass("Enter your Mathpix API key: ")
# os.environ["LANGSMITH_API_KEY"] = getpass.getpass("Enter your LangSmith API key: ")
# os.environ["LANGSMITH_TRACING"] = "true"
Installation
Install langchain-community.
%pip install -qU langchain-community
Initialization
Now we are ready to initialize our loader:
from langchain_community.document_loaders import MathpixPDFLoader
file_path = "./example_data/layout-parser-paper.pdf"
loader = MathpixPDFLoader(file_path)
Load
docs = loader.load()
docs[0]
Lazy Load
page = []
for doc in loader.lazy_load():
page.append(doc)
if len(page) >= 10:
# do some paged operation, e.g.
# index.upsert(page)
page = []
