当前版本的 Tensorflow Argmax 没有指定“轴”和“维度”参数之间的区别。以下是官方手册中给出的唯一信息：
tf.argmax(input, axis=None, name=None, dimension=None) {#argmax}
Returns the index with the largest value across axes of a tensor.
Args:
input: A Tensor. Must be one of the following types: float32, float64, int64, int32, uint8, uint16, int16, int8, complex64, complex128, qint8, quint8, qint32, half.
axis: A Tensor. Must be one of the following types: int32, int64. int32, 0 <= axis < rank(input). Describes which axis of the input Tensor to reduce across. For vectors, use axis = 0.
name: A name for the operation (optional).
Returns:
A Tensor of type int64.
有人可以澄清吗？究竟是哪一个维度被缩减了？
