👻WordCloud 한글 폰트 문제

• 네이버 영화 리뷰 데이터를 wordcloud로 시각화 하는 과정에서 한글 폰트를 입력하는 부분에서 발생한 오류를 해결하는 과정을 담았습니다.

from wordcloud import WordCloud
import matplotlib.pyplot as plt
%matplotlib inline

wordcloud = WordCloud(font_path=os.path.join(DATA_IN_PATH, 'NanumGothic.ttf')).generate(" ".join(train_review))

plt.figure(figsize=(10, 8))
plt.imshow(wordcloud, interpolation='bilinear')
plt.axis("off")
plt.show()

👩‍🏫내가 설정한 경로에 font를 넣어주자

wordcloud = WordCloud(font_path=os.path.join(DATA_IN_PATH, 'NanumGothic.ttf')).generate(" ".join(train_review))

• 저기 font_path에 NanumGothic.ttf를 직접 다운 받아서 넣어주면 해결!!
  * 저는 나눔고딕.ttf 여기서 다운받았습니다.

🤑clear!!

wordcloud = WordCloud(font_path=os.path.join(DATA_IN_PATH, 'NanumGothic.ttf')).generate(" ".join(train_review))
