THEN Create a fresh virtual environment, uninstall any existing llama-index, then install the latest version from PyPI or from source. If you need to use global_handler, call set_global_handler from llama_index.callbacks.global_handlers before accessing llama_index.global_handler.

from llama_index.callbacks.global_handlers import set_global_handler
set_global_handler(eval_mode='wandb')
import llama_index
handler = llama_index.global_handler
