Odoo 11, uses Python3, which is good, but I wonder what is the best way to read/write to file-like objects. Code which seemed to work like a charm in Py2.7, failed to execute in Py3, thus I wonder what could I be doing wrong... I did changed import Strin
如果不是ARCHIVE类型,可执行add archive <file_name>;命令重新上传资源。 更多上传资源操作,请参见添加资源。 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Resources是否包含第三方包。 如果不包含,可执行create function <function_name> as <'package_to_class'>...
