浅谈Python traceback的优雅处理

刚接触Python的时候，简单的异常处理已经可以帮助我们解决大多数问题，但是随着逐渐地深入，我们会发现有很多情况下简单的异常处理已经无法解决问题了，如下代码，单纯的打印异常所能提供的信息会非常有限。 def func1(): raise Exception("--func1 exception--") def main(): try: func1() except Exception as e: print e if __name__ == '__main__': main() 执行后输出如下： –func1 exception– 通过示例，我们发现

这是一个 Python 错误追踪（traceback），它表明您的代码在执行期间遇到了一个异常错误。错误信息指出您的代码期望得到一个一维数组，但实际上得到的是一个二维数组。可能是因为您的标签 `y` 数据的维度不正确，您可以使用 `ravel()` 函数将标签 `y` 数据转换为一维数组，例如： ``` python y = y.ravel() ``` 这样就能将二维数组转换为一维数组，再传入您的模型中进行训练。
