could you please provide dataset umich-sentiment-train.txt as well?

Here is part of code which you need to paste instead from the book

maxlen = 0
word_freqs = collections.Counter()
num_recs = 0
ftrain = open(os.path.join(DATA_DIR, "training.txt"), 'r')
for line in ftrain:
    label, sentence = line.strip().split("\t")    
    words = nltk.word_tokenize(sentence.lower())
    if len(words) > maxlen:
        maxlen = len(words)
    for word in words:
        word_freqs[word] += 1
    num_recs += 1
ftrain.close()

Just paste this code it will resolve the error you getting
maxlen = 0
word_freqs = collections.Counter()
num_recs = 0
ftrain = open(os.path.join(DATA_DIR, "training.txt"), 'r')
for line in ftrain:
label, sentence = line.strip().split("\t")
words = nltk.word_tokenize(sentence.lower())
if len(words) > maxlen:
maxlen = len(words)
for word in words:
word_freqs[word] += 1
num_recs += 1
ftrain.close()
