python - 如何正确设置特定模块以在 VS 代码中进行调试？

Question

我在关注 instruction by VS code's website但似乎我尝试过的任何方法都没有奏效。

我根据需要创建了一个新配置，但是每当我放置路径时它拒绝在 VS 代码中工作，尽管路径 VS 代码在集成终端窗口中提示当我手动调用它时工作正常。

调试器抛出的错误如下:

然后我尝试手动运行它提示的文件，它运行得很好......

(automl-meta-learning) brandomiranda~/automl-meta-learning/automl/experiments ❯ python /Users/brandomiranda/automl-meta-learning/automl/experiments/experiments_model_optimization.py
--> main in differentiable SGD
-------> Inside Experiment Code <--------

---> hostname:

Files already downloaded and verified
Files already downloaded and verified

即使我将鼠标悬停在路径名上并使用 command + click 单击它然后它将我带到 VS 代码中的路径。这似乎很奇怪。所以不知何故，只有当我在调试器模式下运行它时它才不起作用。为什么？

您正在使用 module而不是 program在 launch.json .使用模块时，您必须只传递模块\子模块名称，而不是整个路径。 Visual Studio 然后会加载指定的模块并执行它的 __main__.py文件。

这将是正确的输入，假设 automl 是一个模块并且 Experiments 是一个子模块:
"module": "automl.experiments"
如果您想直接指向您的脚本，您可以使用之前使用的路径，只需更改 module至program :
"program": "${workspaceFolder}/automl/experiments/experiments_model_optimization.py"
