Paddle/model这个目录下载下来之后， 在text_classification执行run.sh会报错。

Traceback (most recent call last):
  File "train.py", line 179, in <module>
    main(args)
  File "train.py", line 170, in main

  File "train.py", line 50, in <lambda>
    lambda: paddle.dataset.imdb.train(word_dict)(), buf_size=1000),
TypeError: 'generator' object is not callable

原因是因为Paddle/python/paddle/v2/dataset/imdb.py中，返回的是reader(), 而不是reader. models-develop/text_classification/train.py调用的语句是

    ┆   train_reader = paddle.batch(
    ┆   ┆   paddle.reader.shuffle(
    ┆   ┆   ┆   lambda: paddle.dataset.imdb.train(word_dict)(), buf_size=1000),
    ┆   ┆   batch_size=100)
