Batch dataset to numpy
웹2024년 6월 4일 · To accomplish this, we use Dataset.reduce () to put all the elements into a TensorArray (symbolically). We now use TensorArray.concat () to convert the whole array into a single tensor. However when we do this the whole dataset becomes flattened into a 1-D array. So we need tf.reshape () to get it back into our original tensor's shape, plus an ... 웹2024년 5월 22일 · I am trying to understand the behavior of Dataset.batch.
