同样Python3下也是通过列表来循环所有key,跟原字典不冲突,所以遍历不会奔溃。 为什么Python3下需要需要list()操作,分析如下: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 nock:lab nock$ python2.6Python2.6.9(unknown,Jul142015,19:46:31)[GCC4.2.1Compatible AppleLLV

原因二的解决措施:通过MaxCompute客户端执行desc function <function_name>;命令,检查输出结果中的Class及Resources的正确性。 如果不正确,需要执行create function <function_name> as <'package_to_class'> using <'resource_list'>;命令重新注册函数,其中package_to_class为Python脚本名.类名,resource_list为MaxCompu...
