The provided api code example didn't work!

Thanks for sharing the project!

When I try to use the provided api to generate 3d objects related descriptions, the .npy path is valid on my computer, the example.json is as follows {"raw":{"a":1,"b":2},"serialized":null}. I am not clear what the exact format of the json file, so I just set a very simple one.

from gradio_client import Client

client = Client("http://101.230.144.196/")
result = client.predict(
    "Object ID",    # str in 'Input Method' Radio component
    "b4bbf2116b1a41a5a3b9d3622b07074c", # str in 'Object ID Input' Textbox component
    "data/modelnet40_c/data_background_1.npy",  # str (filepath or URL to file) in 'Upload Point Cloud File (PLY, NPY, etc.)' File component
    "example.json", # str (filepath to JSON file) in 'parameter_15' Chatbot component
    fn_index=4
)
print(result)

The server returned the following error.

I am not sure why the error ocurred.

1. Can you provide an example json file, including all neccessary keys and values? Since the json file is required in most api call functions.
2. Can you provide some insights to help me figure out the error?

Thanks.

Hi,

I am afraid the online demo cannot be used as API (I haven't tried this). You may download the model checkpoints and run the model on your local machine.

As for the return json format, you can check the code of our gradio demo: pointllm/eval/chat_gradio.py

Best, Runsen

But in your project page, you provided the API document, shown in below. I followed the instruction but didn't succeed.

Also, I didn't find anything related to json format in pointllm/eval/chat_gradio.py.

That’s provided by Gradio by default and my demo is not intended to be used as API. You may check Gradio’s doc and I am not sure if it will work or not.

@RunsenXu Thanks for your reply. Before that I thought the doc was written by yourself. Now I get that the doc was generated by the Gradio by default. Thanks.
