tf.estimator无法使用

Open ddgetget opened this issue 3 years ago • 12 comments

TypeError: Tensor objects are only iterable when eager execution is enabled. To iterate over this tensor use tf.map_fn.

TypeError: Tensor objects are only iterable when eager execution is enabled. To iterate over this tensor use tf.map_fn.

信息有点不太具体，不过根据我的经验，这种错误往往发生在input_fn或者模型的输入这块有点问题，建议在这块debug一下

请问找到问题原因了吗

请问是什么问题呢？ sh run_event_role.sh 后

见楼上的回答，可能是input的数据格式有问题，需要debug一下，看具体模型对应的正确的输入数据格式

请问您是怎么调试成功的？ 我依照作者在知乎里的回答“一种是多分类形式，一种是两个类型label，分别预测起始位置，你这个问题应该是模型用的是预测起始位置，但是实际上加载的label是多分类，建议你看一下代码，换成加载预测起始位置的数据”，把“train_helper.py”的118行和123行分别改成“labels_start_train.npy”和“labels_start_dev.npy”但还是会报错。

已经难过到心有戚戚、食不下咽、日夜垂泪的地步。

谢谢！ 调通了，原来是少加了终止位置end_labels。 我终于又能吃得下饭了【泪目】
