 ## 3.典型示例
-所有Pipeline示例在[examples/pipeline/](../python/examples/pipeline) 目录下，目前有7种类型模型示例：
-- [PaddleClas](../python/examples/pipeline/PaddleClas) 
-- [Detection](../python/examples/pipeline/PaddleDetection)  
-- [bert](../python/examples/pipeline/bert)
-- [imagenet](../python/examples/pipeline/imagenet)
-- [imdb_model_ensemble](../python/examples/pipeline/imdb_model_ensemble)
-- [ocr](../python/examples/pipeline/ocr)
