My map_fn converts string type 1D tensor to double 1D tensor computes a single scalar for each row (intersection) and the output of map_fn returns a 1D vector. This is impossible to do in vectorization @GoingMyWay . 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.: The simplest version of `map_fn` repeatedly applies the callable `fn` to a sequence of elements from first to last. The elements are made of the tensors unpacked from `elems`. `dtype` is the data type of the return I am trying to create a custom layer that calculates the forward kinematics for a robotic arm using 'DH parameters'.
I was trying to apply some highway layers separately on each individual element in a tensor, so i figure map_fn might be the best way to do it. What I'm after is the ability to apply a tensorflow op to each element of a 2d tensor e.g. input=tf.Variable([[1.0, 2.0],[3.0, 4.0]) myCustomOp=#some kind of custom op that operates on 1D t… 1 tensor map_fn iterate function use this python over multiple map 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。 import tensorflow as tf import tensorflow.contrib.eager as tfe tfe.enable_eager_execution() x = [[2.]] m = tf.matmul(x, x) It's straightforward to inspect intermediate results with print or the Python debugger. print(m) # The 1x1 matrix [[4.]] Dynamic models can be built with Python flow control.

This function is quite useful in combination with complex tensorflow operation that operate only on 1D input
내가 찾은 유일한 방법은 tf.map_fn를 중첩 사용하는 것입니다. 그러므로: import tensorflow as tf import time import numpy as np a_size = 64 b_size = 256*256 n

tf.map_fn()函数定义如下： tf.map_fn( fn, elems, dtype=None, parallel_iterations= 10, back_.

Transforms elems by applying fn to each element unstacked on axis 0. (deprecated arguments) tf.map_fn ( fn, elems, dtype=None, parallel_iterations=None, back_prop=True, swap_memory=False, infer_shape=True, name=None, fn_output_signature=None ) Warning: SOME ARGUMENTS ARE DEPRECATED: (dtype).
However, a transform expressed using `map_fn` is still typically less

def map_fn_switch(fn, elems, use_map_fn=True, **kwargs): """Construct the graph with either tf.map_fn or a python for loop. 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.

However, having a for loop make the graph much longer to build and can consume too much RAM on distributed setting. Tensorflow map_fn, from the docs, map on the list of tensors unpacked from elems on dimension 0.
