WebSep 11, 2024 · How does dataset.shuffle (1000) actually work? More specifically, Let's say I have 20000 images, batch size = 100, shuffle buffer size = 1000, and I train the model for 5000 steps. 1. For every 1000 steps, am I using 10 batches (of size 100), each independently taken from the same 1000 images in the shuffle buffer? WebWith tf.data, you can do this with a simple call to dataset.prefetch (1) at the end of the pipeline (after batching). This will always prefetch one batch of data and make sure that there is always one ready. dataset = dataset.batch(64) dataset = dataset.prefetch(1) In some cases, it can be useful to prefetch more than one batch.
