body: <p>I am trying to classify several languages from a combination of tweets texts. I am getting <code>classify</code> import error. </p>
  
  <pre><code>import langid
  
  df1 = pd.read_csv(old_dir+"\\"+"merged_all_csv.csv", sep=',',encoding = "ISO-8859-1",error_bad_lines = False)
          tweetText = df1.TweetText
          for t in tweetText:
              x = langid.classify(str(t))
              if lang_dict[x[0]] not in lang:
                  lang[lang_dict[x[0]]] = 1
              else:
                  lang[lang_dict[x[0]]] = lang[lang_dict[x[0]]] + 1
  
          for k, v in lang.items():
              df.set_value(q, 'Language', k)
              df.set_value(q, 'Count', v)
              q = q + 1
  
          df.to_csv(new_dir+'\\Language_count.csv', sep=',', index=False)
  </code></pre>
  
  <p>Error:</p>
