用Wordcloud生成中文詞雲時遇到的問題

import jieba
import wordcloud

f= open ('ciyun.txt',encoding='utf-8')
t=f.read()
f.close()
ls=jieba.lcut(t)
txt=" ".join(ls)

w=wordcloud.WordCloud(font_path="微軟雅黑粗體.ttf",width=1000,height=700,background_color="white")
w.generate(txt)
w.to_file("wordcloud.png")

Traceback

在生成中文詞雲時老是跳出這個問題，而且這段程式碼使我直接拿的老師上課時講的。自己在網上搜索了很久，都沒能找到解答，最後只能將程式中的程式碼一行一行的刪除，看時什麼位置出現的這個bug，當刪到font_path="微軟雅黑粗體.ttf"這部分時，bug才消失，這才明白原來是自己沒有下載對應的字型檔案。上課老師也是沒有講，我還天真的以為字型檔案是Python平臺自帶的，果然是我太天真了，在網上下載了一個ttf檔案就執行成功了。
