TensorFlow 2.0 Quick Start Guide

Setting up our environment

First, we need to import the dependencies:

import tensorflow as tfimport kerasimport numpy as npfrom sklearn.model_selection import train_test_splitfrom os import walk

You may need to run pip install sklearn. Next, we will establish some constants for later use:

batch_size = 128img_rows, img_cols = 28, 28 # image dimensions

Next, we will use the os.walk method to collect the filenames of datasets from the data_files folder:

Note that the filenames are collected in the list variable filenames.

data_path = "data_files/" for (dirpath, dirnames, filenames) in walk(data_path):     pass # filenames accumulate in list 'filenames'print(filenames)

The filenames (which correspond to the label categories) are as follows for our ...
