The most challenging part of deep learning is labeling, as you’ll see in part one of this two-part series, Learn how to classify images with TensorFlow. Proper training is critical to effective future classification, and for training to work, we need lots of accurately labeled data. In part one, I skipped over this challenge by downloading 3,000 prelabeled images. I then showed you how to use this labeled data to train your classifier with TensorFlow.
