我正在使用以下代码来训练HAN Network。 Code Link
我已经成功地训练了模型,但是当我尝试使用keras load_model加载模型时,出现以下错误- 未知层:AttentionWithContext
答案 0 :(得分:0)
根据您共享的链接,模型在模型中添加了一个明确定义的图层AttentionWithContext()。当您尝试使用keras的load_model加载模型时,该方法会显示错误,因为该层不是keras内置的,要解决此问题,您可能必须在代码中再次定义该层,然后再使用load_model加载模型。在尝试加载模型之前,请尝试在提供的链接(https://www.kaggle.com/hsankesara/news-classification-using-han/notebook)中编写类AttentionWithContext(layer)。

在AttentionWithContext.py文件中添加以下功能:
def create_custom_objects():
instance_holder = {"instance": None}
class ClassWrapper(AttentionWithContext):
def __init__(self, *args, **kwargs):
instance_holder["instance"] = self
super(ClassWrapper, self).__init__(*args, **kwargs)
def loss(*args):
method = getattr(instance_holder["instance"], "loss_function")
return method(*args)
def accuracy(*args):
method = getattr(instance_holder["instance"], "accuracy")
return method(*args)
return {"ClassWrapper": ClassWrapper ,"AttentionWithContext": ClassWrapper, "loss": loss,
"accuracy":accuracy}
加载模型时:
from AttentionWithContext import create_custom_objects
model = keras.models.load_model(model_path, custom_objects=create_custom_objects())
model.evaluate(X_test, y_test) # or model.predict
