demo:recommendation,evaluate error

[Ayle3125]

Here is the tutorial from https://github.com/PaddlePaddle/Paddle/blob/develop/doc/tutorials/rec/ml_regression_cn.rst:

在训练了几个轮次以后，你可以对模型进行评估，得到最好轮次下的模型。运行下面命令即可：

./evaluate.sh
你将看到如下的信息：

Best pass is 00009, error is 3.06949, which means predict get error as 0.875998002281
evaluating from pass output/pass-00009
然后，你可以预测任何用户对于任何一部电影的评价，运行下面命令即可：

python prediction.py 'output/pass-00009/'

In my computer, it looks like:

$ ./evaluate.sh
File "<string>", line 1, in
ValueError: could not convert string to float:
Best pass is , error is , which means predict get error as
evaluating from pass output/pass-

Could someone help me, please?
