LangChain - Text Splitting
You run this code snippet:
chunker = SemanticChunker(chunk_size=80, chunk_overlap=90)

Why does it raise an error?
Achunk_overlap cannot be greater than chunk_size
Bchunk_size must be a string, not an integer
Cchunk_overlap must be zero or negative
Dchunk_size and chunk_overlap must be equal
Step-by-Step Solution
Solution:

  1. Step 1: Understand parameters

    chunk_size defines the max size of each chunk, chunk_overlap defines how much chunks overlap.

  2. Step 2: Check parameter constraints

    chunk_overlap cannot exceed chunk_size, otherwise overlap is larger than chunk itself.

  3. Final Answer:

    chunk_overlap cannot be greater than chunk_size -> Option A

  4. Quick Check:

    chunk_overlap (90) > chunk_size (80)? Yes. [OK]
Quick Trick: Overlap must be less than or equal to chunk size [OK]
Common Mistakes:
  • Assuming chunk_overlap can be larger than chunk_size
  • Confusing data types for parameters
  • Thinking chunk_overlap must be zero or negative
