这个错误通常发生在尝试定义一个异常类但没有正确地从 BaseException(或其子类,如 Exception)继承时。在 Python 中,所有自定义的异常类都必须继承自 BaseException 或其子类,否则解释器无法识别它们为有效的异常类型。 4. 提供解决“exceptions must derive from BaseException”错误的方法 要解决这个错误,需要确保自定...
TypeError:exceptions must be old-style classes or derived from BaseException, not str. 使用python3,主动使用raise 'xxxxxx'抛出异常也是一样报错:TypeError:exceptions must derive from BaseException. 2、解决方法 根据报错描述,抛出的异常必须源于基异常,BaseException是所有异常类的基类,可以使用下列方法抛出异常...
解决方案: 其实,把上面那个代码里面的 “ elif netG == 'refineDepth': ” 改成 “elif netG == 'refineD':” 就可以了。
raise FooError('无效的值:s') TypeError: exceptions must derive from BaseException 异常必须从基础异常类中派生。然后看了下自己的第一行。用的是def,这是创建了一个方法。。而不是一个类,简单的语法错误。只要将第一行的def改成class class FooError(ValueError): pass def foo(s): n=int(s) if n=...

Furthermore, yourtryblock probably encompasses some C++ library code that could throw things likestd::out_of_range,std::invalid_argument, or a plain oldstd::exception. And of course if your code interacts with other libraries, you will want to catch the exceptions thrown by those other librar...
