THEN The 'global_handler' is dynamically set via the 'set_global_handler' function from 'llama_index.callbacks.global_handlers'. Before using any LLM integration (e.g., Ollama) that triggers the handler, call 'set_global_handler' with the appropriate evaluation mode. Alternatively, ensure a fresh virtual environment and install the latest llama-index from source using 'pip install git+https://github.com/run-llama/llama_index.git'.

import llama_index
from llama_index.callbacks.global_handlers import set_global_handler
set_global_handler(eval_mode='default')  # or specify your mode
handler = llama_index.global_handler
