如何在已处理的异常上停止 PyCharm 的 break/stop/halt 功能（即仅在 python 未处理的异常上中断）？

Question

我知道 PyCharm 正在暂停我所有的异常，即使是我在 try except 块中处理的异常。我不希望它在那里中断 - 我正在处理并且可能期待一个错误。但是我确实希望它停止并暂停执行的所有其他异常（例如，以便我拥有程序状态并对其进行调试）。

如何做到这一点？

我尝试进入 python 异常断点选项，但我没有看到像“仅在未处理的异常时中断”这样的选项，例如这些建议：

注意这是我的当前状态，请注意它是如何在我的 try 块中停止的...:(

我试过了：

In your link here intellij-support.jetbrains.com/hc/en-us/community/posts/… the poster Okke said they solved this issue adding --pdb to the 'addition arguments', which someone later said they probably meant interpreter options.

但没有成功出现错误：

/Users/brandomiranda/opt/anaconda3/envs/meta_learning/bin/python --pdb /Applications/PyCharm.app/Contents/plugins/python/helpers/pydev/pydevd.py --cmd-line --multiproc --qt-support=auto --client 127.0.0.1 --port 58378 --file /Users/brandomiranda/ultimate-utils/tutorials_for_myself/try_catch_pycharm_issues/try_catch_with_pickle.py
unknown option --pdb
usage: /Users/brandomiranda/opt/anaconda3/envs/meta_learning/bin/python [option] ... [-c cmd | -m mod | file | -] [arg] ...
Try `python -h' for more information.

Answer 1

我认为它实际上已经在工作了，但实际上您没有捕捉到正确的错误。在你的代码中你有：

try:
    pickle.dumps(obj)
except pickle.PicklingError:
    return False

但是抛出的错误是AttributeError。所以为了避免你需要这样的东西：

try:
    pickle.dumps(obj)
except (pickle.PicklingError, AttributeError):
    return False

Answer 2

不确定为什么 pycharm 在 except 错误的情况下会按照它的方式行事，但这行得通：

def is_picklable(obj: Any) -> bool:
    """
    Checks if somehting is pickable.

    Ref:
        - 
        - pycharm halting all the time issue:

    import pickle
    try:
        pickle.dumps(obj)
    except:
        return False
    return True
