Question

搜索各种资源后，主要来自stackoverflow。我可以让我的代码在我的笔记本电脑上运行以下python版本（安装了Windows 10） 1. WinPython3.4 64位 2. WinPython3.4 32位 3. Python 2.7 32位及其virtualenv 4. Python 2.7 64位及其virtualenv

然后我希望它部署到aws lambda。为此，我尝试逐一为所有上述选项提供两个选项 1.只需压缩.py文件即可获得代码和引用的dll 2.代码的zip .py文件和带有3＆amp;的引用的dll 4 virtualenv

但在所有这些情况下，我在cloudwatch中收到“模块初始化错误：/var/task/TDNN.dll：无效的ELF标题”错误消息。

我环顾四周，但没有找到任何解决办法。我会感谢任何帮助/指针。 Thnx提前。

以下是代码

默认的AWS机器运行Linux，不支持dll，这是针对Windows的。您必须使用wine模拟Windows或查找本机Linux解决方案。

AFAIK亚马逊还提供Windows机器，这是一种选择。

通常，您应该拥有一个与您的部署环境相匹配的开发环境，至少在操作系统和体系结构等基础知识上。
