ObjectReplace¶

class agentlego.tools.ObjectReplace(sam_model='sam_vit_h_4b8939.pth', grounding_model='glip_atss_swin-t_a_fpn_dyhead_pretrain_obj365', device='cuda', toolmeta=None)[源代码]

A tool to replace the certain objects in the image.

参数:

sam_model (str) – The model name used to inference. Which can be found in the segment_anything repository. Defaults to sam_vit_h_4b8939.pth.
grounding_model (str) – The model name used to inference. Which can be found in the MMdetection repository. Defaults to glip_atss_swin-t_a_fpn_dyhead_pretrain_obj365.
device (str) – The device to load the model. Defaults to ‘cuda’.
toolmeta (None | dict | ToolMeta) – The additional info of the tool. Defaults to None.

默认工具信息¶

名称: ObjectReplace
描述: This tool can replace the specified object in the input image with another object, like replacing a cat in an image with a dog.
输入:
- image (ImageIO): The image to edit.
- text1 (str): The object to be replaced.
- text2 (str): The object to replace with.
输出:
- ImageIO

Example¶

Use the tool directly (without agent)

from agentlego.apis import load_tool

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

# apply tool
image = tool('examples/demo.png', 'cat', 'a white dog')
print(image)

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('ObjectReplace', device='cuda').to_lagent()
agent = ReAct(GPTAPI(temperature=0.), action_executor=ActionExecutor([tool]))

# agent running with the tool.
img_path = 'examples/demo.png'
ret = agent.chat(f'According to the image `{img_path}`, replace the cat with a white dog in the image.')
for step in ret.inner_steps[1:]:
    print('------')
    print(step['content'])
