Tensorflow text_generation

Question

我正在处理代码https://www.tensorflow.org/tutorials/sequences/text_generation当我到达该行时，会产生以下错误。 sampled_indices = tf.random.categorical(example_batch_predictions[0], num_samples=1) sampled_indices = tf.squeeze(sampled_indices,axis=-1).numpy()错误AttributeErrorTraceback (most recent call last)在----> 1 sampled_indices = tf.random.categorical(example_batch_predictions[0], num_samples=1)2 sampled_indices = tf.squeeze(sampled_indices,axis=-1).numpy()AttributeError: module 'tensorflow._api.v1.random' has no attribute 'categorical'系统信息 - TensorFlow 版本：Ubuntu 上的 1.12 Jupyter NoteBooks可能缺少什么的任何指示？我想知道是否缺少导入？
