Are you running Python in a proxy environment?

I had the same issue as you. I tested the following curl command in the terminal:

curl localhost:11434/api/embed -d "{\"model\":\"nomic-embed-text\",\"input\":\"why is the sky blue?\"}"

It worked because curl does not use a proxy by default. However, Python code might be going through a proxy, which could be causing the issue.

To fix this, I executed the following commands in the terminal:

export http_proxy=''
export https_proxy=''
export all_proxy=''

After doing this, my Python code worked as expected—no errors, and it successfully generated text using DeepSeek.

However, there's still an issue: it seems that we can't completely disable the proxy within the code itself. I've tried multiple approaches, but none worked. This might be a bug in the Ollama Python SDK when handling proxies.

For example, I tried:

os.environ['ALL_PROXY'] = ''
os.environ['all_proxy'] = ''
os.environ['https_proxy'] = ''
os.environ['http_proxy'] = ''

or

os.environ.pop('ALL_PROXY', None)
os.environ.pop('all_proxy', None)
os.environ.pop('https_proxy', None)
os.environ.pop('http_proxy', None)

But the issue persists.
