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的错误信息，提示无法找到名为'cv2'的模块。这通常是因为您的Python环境中缺少OpenCV库导致的。您需要先安装OpenCV库，可以使用pip来安装，命令为：pip install opencv-python。如果您已经安装了OpenCV，但仍然出现此错误，则可能需要检查是否有其他的Python环境或者是否需要添加OpenCV库到您的Python环境变量中。
