因为Python2转Python3的原因，《机器学习实战》第4章的
emailText = open('email/ham/6.txt').read()需要改为emailText = open('email/ham/6.txt','rb').read()但之后调用listOfTokens = regEx.split(emailText)
会出现
TypeError: cannot use a string pattern on a bytes-like object上网搜索后发现可以用下面方式解决：
emailText = emailText.decode('GBK')或直接emailText = open('email/ham/6.txt','rb').read().decode('GBK') 2 0
