    • Reasoning with models, such as text-to-image generation, image editing, and other operations.
from transformers import AutoModelForVision2Seq, AutoProcessor

# 加载模型和处理器
model = AutoModelForVision2Seq.from_pretrained("AIDC-AI/Ovis-U1-3B")
processor = AutoProcessor.from_pretrained("AIDC-AI/Ovis-U1-3B")

# 准备输入数据(文本或图像)
inputs = processor(text="描述一个美丽的日出场景", return_tensors="pt")

# 进行推理
outputs = model.generate(**inputs)

# 处理输出结果
result = processor.decode(outputs[0], skip_special_tokens=True)
print(result)
  • local deployment: Download the model code and related resources from the GitHub repository and follow the documentation for installation and configuration.
