[Python] Error while installing python package: llama-cpp-python

I am using Llama to create an application. Previously I used openai but am looking for a free alternative. Based on my limited research, this library provides openai-like api access making it quite easy to add into my prexisting code. However this library has errors while downloading. I tried installing cmake which did not help.

Although not directly related to this question, these are other questions I am unable to get answers for:

1. Does this library use Llama or Llama 2?
2. Will this be secure on a Python Flask Application?
