What is equivalent to map followed by batch in TensorFlow?
Allocates map_func on consecutive batch size elements of this dataset and then combines them into one batch. Functionally, it is equivalent to map followed by batch. This API is temporary and deprecated as the input pipeline optimization now merges consecutive map and batch operations automatically.

How does TensorFlow batch_matmul work in NumPy?
Suppose you have array batch size nxm and array batch size mxk. Now, for each pair of them, it calculates nxm X mxk, which gives you an nxk matrix. You will have a batch size of them. Now you can do it using tf.einsum, as of Tensorflow 0.11.0rc0. Multiply matrix M2 with each frame (3 frames) in each batch (2 batches) in M1.
Can a reshape with matmul be used in TensorFlow?
If you’re trying to matrix multiply each matrix in the 3D tensor by the matrix that is the 2D tensor, like Cijl = Aijk * Bkl, you can do it with a simple reshape. It seems that in TensorFlow 1.11.0 the docs for tf.matmul incorrectly say that it works for range >= 2.
How to update tf.data.experimental.map and batch?
Instructions for updating: use tf.data.Dataset.map (map_func, num_parallel_calls) followed by tf.data.Dataset.batch (batch_size, drop_remainder). Static optimizations of tf.data will take care of using the merged implementation. Allocates map_func on consecutive batch size elements of this dataset and then combines them into one batch.
How does TensorFlow reduce global data processing time?
Now use the num_parallel_calls argument of the interleaved transform. This loads multiple datasets in parallel, reducing waiting time to open files. This time, as the data runtime diagram shows, the reading of the two data sets is done in parallel, which reduces the overall data processing time.
What is the default argument of tf.dataset.interleave?
The default arguments to the tf.data.Dataset.interleave transform cause it to interleave individual samples from two data sets sequentially. This data runtime plot allows you to exhibit the behavior of the interleaved transformation, alternately sampling the two available data sets.
