PydanticSchemaGenerationError

I tried running python gradio_demo.py --trex2_api_token <your_token>, but I got the following error.

Hi @08D20088
Can you try to upgrade the gradio to the latest version? This looks like a gradio error.

[08D20088]

Thank you so much for your response.
For compatibility with gradio-image-prompter, I downgraded gradio to version 4.44.1 even though it's not the latest, and tried again.
However, I got the following error:

python3 gradio_demo.py --trex2_api_token <token>

python3 gradio_demo.py --trex2_api_token

I think you should replace with your own token. You can get a free token at https://cloud.deepdataspace.com/request_api.

If this still does not work, maybe it is caused by the upgrade of dds_cloudapi_sdk package, please let me know and I will upgrade the code to the latest package version

@Mountchicken

Thank you for your reply.
I downgraded the version of 'dds_cloudapi_sdk' to 0.1.1 and tried again, but I encountered the same error.

File "/usr/local/lib/python3.10/dist-packages/dds_cloudapi_sdk/tasks/base.py", line 79, in trigger
    raise RuntimeError(f"Failed to trigger task, error: {rsp_json['msg']}")
RuntimeError: Failed to trigger task, error: Resource Not Found. API docs: https://cloud.deepdataspace.com/docs

But, if I follow the example on https://pypi.org/project/dds-cloudapi-sdk/ and run the code below, in another environment.

# 1. Initialize the client with your API token.
from dds_cloudapi_sdk import Config
from dds_cloudapi_sdk import Client

token = "token"
config = Config(token)
client = Client(config)

# 2. Upload local image to the server and get the URL.
infer_image_url = "https://dds-frontend.oss-accelerate.aliyuncs.com/static_files/playground/grounding_DINO-1.6/02.jpg"
# infer_image_url = client.upload_file("path/to/infer/image.jpg")  # you can also upload local file for processing

# 3. Create a task with proper parameters.
from dds_cloudapi_sdk.tasks.v2_task import V2Task

task = V2Task(api_path="/v2/task/trex/detection", api_body={
  "model": "T-Rex-2.0",
  "image": infer_image_url,
  "targets": ["bbox", "embedding"],
  "prompt": {
    "type": "visual_images",
    "visual_images": [
      {
        "image": infer_image_url,
        "interactions": [
          {
            "type": "rect",
            "category_id": 12,
            "rect": [159.78119507908616, 186.52658172231986, 337.2996485061512, 309.2963532513181],
          }
        ]
      }
    ]
  }
})
# task.set_request_timeout(10)  # set the request timeout in seconds，default is 5 seconds

# 4. Run the task.
client.run_task(task)

# 5. Get the result.
print(task.result)

And since I obtained the following results, I believe the API is being called correctly.

{'embedding': 'W3siY2F0ZWdvcnl・・・・・4bWZrT1BBPT0ifV0=', 'objects': [{'bbox': [599.4776000976562, 0.35921478271484375, 898.8107299804688, 182.97488403320312], 'category_id': 12, 'score': 0.30459216237068176}]}

Follow is a list of Python libraries that were installed in my environment when I tried the above code.
