Fix the code request exception when OLLAMA_HOST=0.0.0.0

[xuzexin-hz]

I have been following ollma. When ollma launched the ollama-python project last year, I immediately started to use it for testing. Unfortunately, an error occurred at that time,because according to the description on https://github.com/ollama/ollama/blob/main/docs/faq.md, OLLAMA_HOST=0.0.0.0:11434, but ollama-python does not work by default.
After debugging, I found that os.environ['OLLAMA_HOST'] = 'http://127.0.0.1:11434' is required. If this configuration is used in every project, the code seems a bit redundant. Later, I also communicated with some people about this issue（issue #450、issue #455、issue #407）.
Today I found that this problem still exists. Oh my God, so many people have encountered this problem, which means it is a common problem. I think we should avoid it.

Hey, I'm still running into that issue where ollama-python won't work with 0.0.0.0:11434. I'm running ollama serve with Docker. Could you share how to set OLLAMA_HOST = 'http://127.0.0.1:11434/'?

Hi @xuzexin-hz

Serving Ollama on 0.0.0.0 is needed to make it available, but on the client side it needs to be specified to 127.0.0.1 (or your deployed instance) to connect to Ollama. This doesn't need to be in the code, however I will look into making a comment in our docs somewhere.
