Thanks to Mikyo for the Help! David Will Give It a Try

Hi David. The llama-index team has resolved their issue and you can now update to the latest version using the following.

pip install -U llama-index-callbacks-arize-phoenix

Thanks, Roger -- I tried but still have the same problem, so I'll wait a bit to let things ripple through the system and then try another attempt. Regards, David

ok. sorry about that. One thing we found helpful when we worked on this migration was that sometimes everything needs to be uninstall and re-install again just to purge the dependency tree

pip uninstall llama-index-core llama-index llama-index-callbacks-arize-phoenix llama-index-llms-openai

then reinstall

pip install -U llama-index-core llama-index llama-index-callbacks-arize-phoenix llama-index-llms-openai
