Hey @msamwelmollel, nice to see you back in the labyrinth of code! 🌀

The error "ModuleNotFoundError: No module named 'llama_index.core.llms.llama_utils'" is occurring because with the introduction of LlamaIndex v0.10.0, many imports have changed.

If you want to import specific functions from 'llama_index.core.llms.llama_utils', you have two options:

1. Use temporary legacy imports: You can update your imports to use the legacy import package. This is a large change, but it allows existing code to migrate to v0.10.0 with minimal impact. For example, you can update your imports from:

from llama_index.core.llms.llama_utils import (
    messages_to_prompt,
    completion_to_prompt,
)

to:

from llama_index.legacy.core.llms.llama_utils import (
    messages_to_prompt,
    completion_to_prompt,
)

2. Full migration: You can use the command-line tool that comes with pip install llama-index and pip install llama-index-core to update existing code and notebooks. After installing v0.10.0, you can upgrade your existing imports automatically:

llamaindex-cli upgrade-file <file_path>
# OR
llamaindex-cli upgrade <folder_path>

This will update the import statements in your .py and .md files, and new requirements will be printed to the terminal. For notebooks, new pip install statements are inserted and imports are updated.

For more details, you can refer to the migration guide for v0.10.0.

pip install llama-index-llms-llama-cpp (looks like you already did this)
from llama_index.llms.llama_cpp.llama_utils import messages_to_prompt, completion_to_prompt
