Question

我正在尝试基于ml上的代码从GitHub上的数据集中获取并创建数据集。但是问题是，当我尝试运行此代码时，我不断收到HTTP错误404错误消息。不知道是什么原因造成的。

这是我收到的错误消息的详细回溯：

print (df1.to_json(orient='records'))
[{"CUST_ID":1000,
  "CUST_LAST_UPDATED":1556879045879,
  "CUST_NAME":"newly pdated_3_file"},
 {"CUST_ID":1001,
  "CUST_LAST_UPDATED":1556879052416,
  "CUST_NAME":"heeloo1"}]

这是我正在使用的代码
