@bofinbabu which OS are you on + how are you pip installing llama-index?

[hushujie]

I had a similar problem on MAC OS(M1), and more error msg is like:
distutils.errors.CompileError: command '/usr/bin/clang' failed with exit code 1.

I solved this by using "conda install numcodecs==0.11.0" instead of "pip install numcodecs==0.11.0"

FYI
