1 from wordcloud import WordCloud 2 import os 3 4 cur_path = os.path.dirname(__file__) 5 6 with open(os.path.join(cur_path, 'love_en.txt')) as fp: 7 txt = fp.read() 8 # print(txt) 9 wordcloud = WordCloud().generate(txt) 10 image = wordcloud.to_image() 11 image.show()
发生错误，错误类型:OSError: cannot open resource
解决方案：添加字体
改正后代码：
1 from wordcloud import WordCloud 2 import os 3 4 cur_path = os.path.dirname(__file__) 5 6 with open(os.path.join(cur_path, 'love_en.txt')) as fp: 7 txt = fp.read() 8 # print(txt) 9 wordcloud = WordCloud(font_path = 'FZLTXIHK.TTF').generate(txt) 10 image = wordcloud.to_image() 11 image.show()
进一步优化代码：
1 from wordcloud import WordCloud 2 import os 3 4 cur_path = os.path.dirname(__file__) 5 6 with open(os.path.join(cur_path, 'love_en.txt')) as fp: 7 txt = fp.read() 8 # print(txt) 9 wordcloud = WordCloud(font_path = 'FZLTXIHK.TTF', # 字体 10 background_color = 'black', # 背景色 11 max_words = 30, # 最大显示单词数 12 max_font_size = 60 # 频率最大单词字体大小 13 ).generate(txt) 14 image = wordcloud.to_image() 15 image.show()
