def prepareData(dataset): X,y=[],[] for words in dataset: X.append([features(untag(dataset), s) for s in range(len(dataset))]) y.append([tag for word,tag in sentences]) return X,y ValueError: too many values to unpack (expected 2)
Here, dataset
is a list and s
is an integer value index of any object in the list.

Answer
The problem is with this line:
y.append([tag for word,tag in sentences])
You don’t tell us what sentences
is, but it’s apparent it’s not what it needs to be.
For example:
sentences = ['this is a test','a quick brown fox'] [tag for word,tag in sentences] ValueError: too many values to unpack (expected 2)
If your sentences
was a list of two-tuples the code would work:
sentences = [('this is a test','tag1'),('a quick brown fox','tag2')] In [15]: [tag for word,tag in sentences] Out[15]: ['tag1', 'tag2']
