Adds requirements.txt file and openai setup instructions

[cgreening]

This should make it a bit easier for people getting started.

Agreed, we are doing this step anyway as we replicate the notebook

[piedrahitapablo]

It would be great to also add the required python version to run the notebook and maybe pin the dependencies inside the requirements.txt to specific versions since they could break with any major changes to those.

I'm getting

APIRemovedInV1: 

You tried to access openai.ChatCompletion, but this is no longer supported in openai>=1.0.0 - see the README at https://github.com/openai/openai-python for the API.

You can run `openai migrate` to automatically upgrade your codebase to use the 1.0.0 interface. 

Alternatively, you can pin your installation to the old version, e.g. `pip install openai==0.28`

A detailed migration guide is available here: https://github.com/openai/openai-python/discussions/742

so maybe the openai needs to get pinned?

Running the

model = AutoModelForCausalLM.from_pretrained('TheBloke/Llama-2-7b-Chat-GPTQ', device_map=0, torch_dtype=torch.float16)

cell (in Colab) also requires

accelerate
optimum
auto-gptq

[adelton]

For the

from sentence_transformers import SentenceTransformer

cell, sentence_transformers is also needed.

[adelton]

For the

from llama_cpp import Llama

cell, llama-cpp-python seems needed.
