To install from source, download the source package PyYAML-5.1.tar.gz and unpack it. This is a short outline of differences in PyYAML API between Python 2 and yaml.load is as powerful as pickle.load and so may call any Python function. yaml.load accepts a byte string, a Unicode string, an open binary file object, Show example code and courses Python Tutor (code on GitHub) supports: Python 3.6 and 2.7 with limited imports (__future__, abc, operator, pickle, pprint, random, re, string, time, types, unittest, StringIO (Python 2), typing (Python 3)), You'll also need to download the datasets mentioned in this chapter in order to Here are some examples of MNIST digits: 0 1 2 3 4 5.
