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.

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. in this case, the only axis of the input tensor [1,2,3], or [-1,1,-1].

There's no problem with slicing or tf.map_fn(). There seems to be a problem with y_pred. Reason: On iterating, tf.map_fn() returned elements of (None, 1) and slicing too returns this extra 1 at the end which is (None, None, 1). And this happens only with y_pred and not with y_true. Question: So, what's actually wrong with y_pred? 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.

Very similar to this overflow post that was posted yesterday in fact: The official documentation for map_fn shows it should be capable of accepting … 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.: About.
