Fix ModuleNotFoundError
in BitsAndBytes
✅ Solution
The "ModuleNotFoundError" in bitsandbytes usually arises from missing or incompatible dependencies, particularly Triton. Ensure you have the correct version of Triton installed that aligns with your bitsandbytes version; try reinstalling bitsandbytes with `pip install --upgrade bitsandbytes` or building from source following the official documentation if encountering Triton-related issues. If using Triton 3.2 or newer, adapt your code to avoid deprecated modules like `triton.ops` as they have been removed.
