下载代码【可选】:https://github.com/fuzhengwei...- 用于后续测试模型训练代码 配置Visual Studio【你也可以是其他的】,打开以后需要安装 python 插件以及配置登录 github,这样会更利于后续的操作。之后在 Visual Studio 的终端下,查看下 python -V 的版本,如果不是最新安装的 3.x 版本,可以刷新下配置source ....
Grumpy is a Python to Go source code transcompiler and runtime that is intended to be a near drop in replacement for CPython 2.7. The key difference is that it compiles Python source code to Go source code which is then compiled to native code, rather than to bytecode. This means ...
