from os import path
from PIL import Image
import numpy as np
import matplotlib.pyplot as plt
from wordcloud import WordCloud, STOPWORDS
import jieba

file = open('D:\python\CompatingD\Cloud_map\Chinese.txt')
text = file.read()
text = ' '.join(jieba.cut(text))

wordcloud = WordCloud(font_path="simsun.ttf").generate(text)
plt.imshow(wordcloud, interpolation='bilinear')
plt.axis("off")
