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

抱歉给你带来了困扰。问题出在 `voxel_down_sample()` 方法的使用上。在Open3D的最新版本中，`voxel_down_sample()` 方法的参数已经发生了变化。请将步骤3中的代码修改为以下内容： ```python point_cloud_filtered, _ = point_cloud_filtered.voxel_down_sample(voxel_size=0.01) # 使用0.01作为体素大小，可根据需要调整 ``` 这里我们使用 `voxel_down_sample()` 方法的返回值来更新 `point_cloud_filtered` 的值。然后再次运行代码，应该就能够解决这个问题了。如果还有其他问题，请随时告诉我。
