Pipeline使用教程

本文简单介绍如何使用pipeline函数加载模型进行推理。pipeline函数支持按照任务类型、模型名称从模型仓库拉取模型进行进行推理,包含以下几个方面:

  • 使用pipeline()函数进行推理
  • 指定特定预处理、特定模型进行推理
  • 不同场景推理任务示例

环境准备

详细步骤可以参考 快速开始

Pipeline基本用法

下面以中文分词任务为例说明pipeline函数的基本用法

  1. pipeline函数支持指定特定任务名称加载任务默认模型创建对应pipeline对象 执行如下python代码

    from modelscope.pipelines import pipeline
    word_segmentation = pipeline('word-segmentation')
    
  2. 输入文本

    input = '今天天气不错,适合出去游玩'
    print(word_segmentation(input))
    {'output': '今天 天气 不错  适合 出去 游玩'}
    
  3. 输入多条样本

pipeline对象也支持传入多个样本列表输入返回对应输出列表每个元素对应输入样本的返回结果

inputs =  ['今天天气不错,适合出去游玩','这本书很好,建议你看看']
print(word_segmentation(inputs))
[{'output': '今天 天气 不错  适合 出去 游玩'}, {'output': '这 本 书 很 好  建议 你 看看'}]

指定预处理、模型进行推理

pipeline函数支持传入实例化的预处理对象、模型对象从而支持用户在推理过程中定制化预处理、模型。

  1. 首先,创建预处理方法和模型
from modelscope.models import Model
from modelscope.preprocessors import TokenClassificationPreprocessor
model = Model.from_pretrained('damo/nlp_structbert_word-segmentation_chinese-base')
tokenizer = TokenClassificationPreprocessor(model.model_dir)
  1. 使用tokenizer和模型对象创建pipeline
from modelscope.pipelines import pipeline
word_seg = pipeline('word-segmentation', model=model, preprocessor=tokenizer)
input = '今天天气不错,适合出去游玩'
print(word_seg(input))
{'output': '今天 天气 不错  适合 出去 游玩'}

不同场景任务推理示例

下面以一个图像任务:人像抠图('image-matting'为例进一步说明pipeline的用法

import cv2
from modelscope.pipelines import pipeline
img_matting = pipeline('image-matting')
result = img_matting('https://modelscope.oss-cn-beijing.aliyuncs.com/test/images/image_matting.png')
cv2.imwrite('result.png', result['output_png'])
