错误：不能在类似字节的对象上使用字符串模式 情绪分析

如何解决错误：不能在类似字节的对象上使用字符串模式 情绪分析

我正在尝试使用正则表达式和许多其他内容删除 URL 以清理数据，为此我有以下功能

def depure(data):
  '''
  input : data 
  output: data without #URLs,Emails,Characters and single quotes
  '''
  #remove URLs with a regular expressions (not sure if they exist)
  regex = r'https?://\S+|www\.\S+'
  url_pattern = re.compile(regex)
  
  data = url_pattern.sub(r'',data)

  # Remove Emails
  data = re.sub('\S*@\S*\s?','',data)

  # Remove new line characters
  data = re.sub('\s+',' ',data)

  # Remove distracting single quotes
  data = re.sub("\'","",data)
          
  return data

但我不知道为什么，我已经尝试过解决这个错误，但什么也没有。

test_temp = []
#tranform data sequences to list
train_to_list = train_data.tolist()
test_to_list = test_data.tolist()

#for train data
for i in range(len(train_data)):
  train_temp.append(depure(train_data[i]))
train_words = list(sent_to_words(train_temp))
new_train = []
for i in range(len(train_words)):
  new_train.append(detokenize(train_data[i]))

输出错误：

有人可以帮我吗？
