ObjectDetection

Examples

Download the demo resource

wget http://download.openmmlab.com/agentlego/road.jpg

Use the tool directly (without agent)

from agentlego.apis import load_tool

# load tool
tool = load_tool('ObjectDetection', device='cuda')

# apply tool
visualization = tool('road.jpg')

With Lagent

from lagent import ReAct, GPTAPI, ActionExecutor
from agentlego.apis import load_tool

# load tools and build agent
# please set `OPENAI_API_KEY` in your environment variable.
tool = load_tool('ObjectDetection', device='cuda').to_lagent()
agent = ReAct(GPTAPI(temperature=0.), action_executor=ActionExecutor([tool]))

# agent running with the tool.
ret = agent.chat(f'Please detect all objects in the image `road.jpg`.')
for step in ret.inner_steps[1:]:
    print('------')
    print(step['content'])

Set up

Before using the tool, please confirm you have installed the related dependencies by the below commands.

pip install openmim
mim install mmdet

Reference

This tool uses a RTMDet model by default. See the following paper for details.
