LangChain - Text Splitting
You wrote this code for semantic chunking but get an error: 
chunks = chunk_text(text, chunk_size=100, chunk_overlap=150)
What is the likely cause of the error?
Achunk_overlap is larger than chunk_size, causing invalid overlap
Bchunk_size is too large for the text length
CMissing import statement for chunk_text function
Dchunk_size and chunk_overlap must be strings, not integers
Step-by-Step Solution
Solution:

  1. Step 1: Check relationship between chunk_size and chunk_overlap

    Overlap cannot be larger than chunk size because overlap defines how much chunks share content.

  2. Step 2: Identify error cause

    chunk_overlap=150 is greater than chunk_size=100, which is invalid and causes error.

  3. Final Answer:

    chunk_overlap is larger than chunk_size, causing invalid overlap -> Option A

  4. Quick Check:

    Overlap must be ≤ chunk size [OK]
Quick Trick: Overlap cannot exceed chunk size [OK]
Common Mistakes:
  • Setting overlap larger than chunk size
  • Assuming large chunk size causes error
  • Confusing data types for parameters
