我尝试着去跑动识别数字的代码，发现它跑不动（windows10 专业版下），代码附上

train_reader = paddle.batch(
        paddle.reader.shuffle(paddle.dataset.mnist.train(), buf_size=500),
        batch_size=BATCH_SIZE)

try:
    for step_id, data in enumerate(train_reader()):
        print(data)
except BaseException as err:
    print('Some problems')
    print(err)

输出到控制台的信息全为空

Some problem

恳请问是怎么一回事呢？
