This function is mainly for for benchmarking purpose.
The elements are made of the tensors unpacked from elems . dtype is the data type of the return value of fn . In my code, I am using the 6 joint angles as the input of the custom layer (Kinematics_Physics) and I am using tensorflow.map_fn to iteratively calculate the forward kinematics of each set of angles in the input. My goal is to set the 'DH parameters' as the trainable weights and train a … 2018-3-8 · Is there a pytorch api like ‘tf.map_fn’ of tensorflow that I can do some duplicate operations parallelly on GPU? For example, I have 64 tasks in one program, and each of the task have the same input data shape and same cnn network, but with different weights and biases, run these tasks sequencely is a easy way, but it is too slow，so I want to run the these tasks parallelly on GPU. In 2020-12-17 · fn: Function that will be called upon each element in elems.
The elements are made of the tensors unpacked from elems. dtype is the data type of the return value of fn. Users must provide dtype if it is different from the data type of elems.

`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 from tensorflow.
