示例1: str
# 需要導入模塊: from sklearn.feature_extraction.text import TfidfVectorizer [as 別名]
# 或者: from sklearn.feature_extraction.text.TfidfVectorizer import append [as 別名]
colors.append(c)
movieName = movieName.decode('unicode-escape')
genre = genre.decode('unicode-escape')
labels.append(movieName + "\n" + genre)
# get feature vector
feats = g.readline()
elems = feats.split(';')
v = []
for elem in elems:
e = elem.strip().strip("{}")
#print e
#print str(len(vectors)) + " " + str(len(v)) + " string is " + e
v.append(float(e))
vectors.append(v)
# Now use these vectors for tSNE
