1. def reader():
2.          UNK_ID = word_dict["<UNK>"]
3.          word_col = 1
4.          teacher_label_col = 0
5.          for file_name in os.listdir(data_dir):
6.              with open(os.path.join(data_dir, file_name), "r") as f:
7.                       for line in f:
8.                      line_split = line.strip().split("\t")
9.                      word_ids = [
10.                          word_dict.get(w, UNK_ID)
11.                         for w in line_split[word_col].split() ]
12.                      y_value = float(line_split[teacher_label_col])
13.                     yield word_ids, y_value
14.      return reader

this is my reader code, y_value is float type, x value is writed as words_ids like [12, 34, 55]. when run got "ValueError:The input should be a vector, please check your input data." when I try to replace the line 12 to "y_value = [float(line_split[teacher_label_col])]" , got a core bug..
