the code seems to work but as i open the gradio url to test it, its showing error as soon as i put in some question
Please paste your error @DreamyPujara
Please check the output in the terminal from where you ran the app.
I'm having the same issue. It seems it does not like the **PARAMETERS. I've tried systematically removing the parameters, but to no avail. I do have the server running on http://localhost:8000, and can query an image description with an image from a simple python script. And can run os.environ.get("LLAMA_70B") which prints out "http://localhost:8000".
This is the error I see:
File "/XXXXXXX/AI/llava-openai-server/gradio_chat.py", line 60, in predict
for response in CLIENT.generate_stream(query, **PARAMETERS):
File "/XXXXXX/AI/llava-openai-server/gradio-env/lib/python3.12/site-packages/text_generation/client.py", line 243, in generate_stream
