TensorFlow中的高阶函数：tf.map_fn()在TensorFlow中，有一些函数被称为高阶函数（high-level function），和在python中的高阶函数意义相似，其也是将函数当成参数传入，以实现一些有趣的，有用的操作。其中tf.map_fn()就是其中一个。

`map_fn` will apply the operations used by `fn` to each element of `elems`, resulting in `O(elems.shape[0])` total operations. This is somewhat: mitigated by the fact that `map_fn` can process elements in parallel. However, a transform expressed using `map_fn` is still typically less
This function is mainly for for benchmarking purpose. tf.map_fn is dynamic but is much slower than creating a static graph with for loop. Tensorflow map_fn, from the docs, map on the list of tensors unpacked from elems on dimension 0. in this case, the only axis of the input tensor [1,2,3], or [-1,1,-1].
Tensorflow iterate over tensor. tf.map_fn, Suppose that elems is unpacked into values , a list of tensors. The shape of the result tensor is [len(values)] +

Note: `map_fn` should only be used if you need to map a function over the *rows* of a `RaggedTensor`. If you wish to map a function over the: individual values, then you should use: * `tf.ragged.map_flat_values(fn, rt)` (if fn is expressible as TensorFlow ops) * `rt.with_flat_values(map_fn(fn, rt.flat_values))` (otherwise) E.g.:
