The following is my streamlit secrets file:-

The following is my streamlit code:

I have tried all the possible solutions from all the sources. I’m asking anyone to figure out the error.

Hi @Guna_Sekhar_Venkata,

Please avoid sharing API keys publicly in the future. I’ve edited your post to redact your API key but you may still want to retire that API key just in case.

Thanks for guidance. But I’m unable to find the where my code getting error?

4

The host address api-inference.huggingface.com looks wrong. Where did you get it from?

5

Some where in the web. Could you suggest me the correct approach?

6

Which web?

7

Im trying to use hugging face runwayml model

This is what I think is the correct approach: go back to “some where in the web” and check the host address.
