Is this expected? or it is becasue of my local env?

Open ai/examples/rag-with-pytidb.md and review the documented virtual-environment and dependency-installation commands against the reported macOS output. Reproduce the setup steps, checking the Python version and the pytidb==0.0.13 requirement. Done means the instructions clearly state the supported environment and allow the example dependencies to install successfully.
