Transforms elems by applying fn to each element unstacked on axis 0. (deprecated arguments)

If elems is a single tensor and fn 's signature is tf.Tensor->tf.Tensor , then map_fn (fn, elems) is equivalent to tf.stack ( [fn (elem) for elem in tf.unstack (elems)]). E.g.: 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. Let me know if you find a workaround @asorie. Copy link. tf.map_fn() is located on the CPU when calling with integer tensors.

To use eager functionality, you need to change your code. Pre-trained models and datasets built by Google and the community TensorFlow NumPy uses highly optimized TensorFlow kernels that can be dispatched on CPUs, GPUs and TPUs. TensorFlow also performs many compiler optimizations, like operation fusion, which translate to performance and memory improvements.

Higher Order Operators. TensorFlow provides several higher order operators to simplify the common map-reduce programming patterns. 2021-3-19 · This guide is for users of low-level TensorFlow APIs. If you are using the high-level APIs (tf.keras) there may be little or no action you need to take to make your code fully TensorFlow 2.x compatible: Check your optimizer's default learning rate.; Note that the "name" that metrics are logged to may have changed.; It is still possible to run 1.x code, unmodified (except for contrib), in 2021-4-12 · March 03, 2021 — Posted by Daniel Ellis, TensorFlow EngineerNote: This blog post is aimed at TensorFlow developers who want to learn the details of how graphs and models are stored.

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]. Operations are thus 1*-1,2*1 and 3*-1, and the results are repacked giving you the tensor shape.
