Python Tensorflow tf.concat在连接2个张量时引发奇怪的错误

Question

这是我想将2个张量（张量，array_tensor）连接成“ new_tensor”的代码，但是我返回了此错误。

如果它可以帮助我在gpu的Tensorflow 1.14.1-dev20190318上运行

    tensor = None
    array_tensor = None
    dummy_tensor = tf.convert_to_tensor(0.0,dtype=tf.float32)
    dummy_tensor_2 = tf.convert_to_tensor(0.0,dtype=tf.float32)
    dataset = tf.data.Dataset.from_tensors(tensors=(dummy_tensor,dummy_tensor_2))
    for row in float_validation:
        print(row[0])
        tensor = tf.convert_to_tensor(row[0], dtype=tf.float32)
        array_tensor = tf.convert_to_tensor(row[1],dtype=tf.float32)
        new_tensor = tf.concat([tensor,array_tensor],axis=2)
        # dataset = dataset.concatenate(tf.data.Dataset.from_tensors(tensors=(tensor,array_tensor)))
        dataset = dataset.concatenate(tf.data.Dataset.from_tensors(tensors=(new_tensor)))
