19.02.2019 · 1 Answer1. Show activity on this post. You don't need to use tf.data.Dataset.from_generator. Creating dataset from images with tf.data.Dataset.from_tensor_slices writes data chunks in the graph as tf.constant (), wasting memory. With a large enough dataset you can hit Tensorflow's 2GB GraphDef limit.
