The error message you encountered suggests that the name 'PointCloud' is not defined in your code. To resolve this issue, you need to ensure that the 'PointCloud' class or object is imported or defined properly. Here are the steps to follow:

5. Ensure the class is accessible: If the 'PointCloud' class is defined in a separate file or module, make sure it is accessible from the current file. You might need to specify the correct import statement or include the necessary file in your project.

By following these steps, you should be able to resolve the 'NameError: name 'PointCloud' is not defined' issue. Remember to double-check your code for any typos or missing imports.
