1. 数据处理部分

• 执行 python preprocess.py 问题：

   Namespace(dataset='sample')
   -- Starting @ 2019-03-28 05:49:51.411397s
   Traceback (most recent call last):
   File "preprocess.py", line 32, in <module>
       with open(dataset, "r") as f:
   IOError: [Errno 2] No such file or directory: 'sample_train-item-views.csv'

2. 模型训练部分

• python3 下报错：

  Traceback (most recent call last):
  File "train.py", line 131, in <module>
    train()
  File "train.py", line 111, in train
    for data in data_reader.reader(batch_size, batch_size * 20, True):
  File "/home/crim/models/fluid/PaddleRec/gnn/reader.py", line 93, in reader
    random.shuffle(self.input)
  File "/opt/_internal/cpython-3.5.1/lib/python3.5/random.py", line 269, in shuffle
    for i in reversed(range(1, len(x))):
  TypeError: object of type 'zip' has no len()

3. infer部分

• infer模型文件夹建议用try.. except包起来：

  Traceback (most recent call last):
  File "infer.py", line 75, in <module>
    infer(index)
  File "infer.py", line 54, in infer
    model_path, exe)
  File "/usr/local/lib/python2.7/dist-packages/paddle/fluid/io.py", line 1078, in 
   load_inference_model
    raise ValueError("There is no directory named '%s'", dirname)
    ValueError: ("There is no directory named '%s'", './saved_model/epoch_5')
