如何在python中生成孟加拉文字的wordcloud？

如何解决如何在python中生成孟加拉文字的wordcloud？

我尝试了以下代码：

!pip install python-bidi
from wordcloud import WordCloud
from matplotlib import pyplot as plt
from bidi.algorithm import get_display

text="""মুস্তাফিজ"""

bidi_text = get_display(text)
print(bidi_text)
# https://github.com/amueller/word_cloud/issues/367
# https://stackoverflow.com/questions/54063438/create-wordcloud-in-python-for-foreign-language-hebrew
# https://www.omicronlab.com/bangla-fonts.html
rgx = r"[\u0980-\u09FF]+"
wordcloud = WordCloud(font_path='/content/Siyamrupali.ttf').generate(bidi_text)

#wordcloud = WordCloud(font_path='/content/FreeSansBold.ttf').generate(bidi_text)
plt.imshow(wordcloud,interpolation='bilinear')
plt.axis("off")
plt.show()

然后我得到这个错误：

---------------------------------------------------------------------------
ValueError                                Traceback (most recent call last)
<ipython-input-87-56d899c0de07> in <module>()

     13 rgx = r"[\u0980-\u09FF]+"
---> 14 wordcloud = WordCloud(font_path='/content/Siyamrupali.ttf').generate(bidi_text)
     15 
     16 #wordcloud = WordCloud(font_path='/content/FreeSansBold.ttf').generate(bidi_text)

/usr/local/lib/python3.6/dist-packages/wordcloud/wordcloud.py in generate_from_frequencies(self,frequencies,max_font_size)
    381         if len(frequencies) <= 0:
    382             raise ValueError("We need at least 1 word to plot a word cloud,"
--> 383                              "got %d." % len(frequencies))
    384         frequencies = frequencies[:self.max_words]
    385 

ValueError：我们至少需要1个单词才能绘制单词云，得到0。

此行未选择孟加拉语单词：wordcloud = WordCloud（font_path ='/ content / Siyamrupali.ttf'）。generate（bidi_text）

我从这里尝试了几乎所有的孟加拉语言字体：https://www.omicronlab.com/bangla-fonts.html

没有用

解决方法

您没有使用您在词云中定义的regexp 更改。在处理词云中的文本时，它无法匹配模式并返回一个空列表。 在创建词云对象时传递 rgx 变量将解决您的问题。

wordcloud = WordCloud(font_path='/content/Siyamrupali.ttf',regexp=rgx).generate(bidi_text)

这是代码的完整片段。

!pip install python-bidi
from wordcloud import WordCloud
from matplotlib import pyplot as plt
from bidi.algorithm import get_display

text="""মুস্তাফিজ"""

bidi_text = get_display(text)
print(bidi_text)
# https://github.com/amueller/word_cloud/issues/367
# https://stackoverflow.com/questions/54063438/create-wordcloud-in-python-for-foreign-language-hebrew
# https://www.omicronlab.com/bangla-fonts.html
rgx = r"[\u0980-\u09FF]+"
wordcloud = WordCloud(font_path='/content/Siyamrupali.ttf',regexp=rgx).generate(bidi_text)

#wordcloud = WordCloud(font_path='/content/FreeSansBold.ttf').generate(bidi_text)
plt.imshow(wordcloud,interpolation='bilinear')
plt.axis("off")
plt.show()

我使用以下代码在孟加拉语中生成了一个词云。你可以试试：

def generate_Word_cloud(self,author_post,vocabularyWordnumber,img_file,stop_word_root_path):

stop_word_file = stop_word_root_path+'/stopwords-bn.txt'
print(stop_word_file)
f = open(stop_word_file,"r",encoding="utf8")
stop_word = f.read().split("\n")
print(stop_word)

final_text = " ".join(author_post)
print(final_text)
wordcloud = WordCloud(stopwords = stop_word,font_path='/usr/share/fonts/truetype/freefont/kalpurush.ttf',width = 600,height = 500,max_font_size=300,max_words=vocabularyWordnumber,min_word_length=4,background_color="black").generate(final_text)
wordcloud.to_file(img_file)
