Which of the following is the correct way to create a PyPDFLoader instance for a file named document.pdf?
Aloader = PyPDFLoader.read('document.pdf')
Bloader = PyPDFLoader.load('document.pdf')
Cloader = PyPDFLoader('document.pdf')
Dloader = PyPDFLoader.open('document.pdf')
Step-by-Step Solution
Solution:

  1. Step 1: Recall PyPDFLoader instantiation

    PyPDFLoader is instantiated by passing the file path as an argument to its constructor.

  2. Step 2: Identify correct syntax

    The correct syntax is PyPDFLoader('filename.pdf'), not using methods like load, read, or open.

  3. Final Answer:

    loader = PyPDFLoader('document.pdf') -> Option C

  4. Quick Check:

    Constructor usage = loader = PyPDFLoader('document.pdf') [OK]
Quick Trick: Use constructor with file path string directly [OK]
Common Mistakes:
  • Using non-existent methods like load() or read()
  • Forgetting to pass the file path as a string
  • Trying to open the file separately before loader
