标签: rosbag

我正在尝试从Python 3读取rosbag文件。
我安装了ROS2（Eloquent Elusor），它应该支持Python 3。

当我跑步时

import rosbag
bag = rosbag.Bag('test.bag')

从Python 2.7开始，它可以工作了。
当我在 Python 3 中尝试同样的操作时，我得到：

ModuleNotFoundError: No module named 'rosbag'

我也尝试过诸如：sudo apt install python-rosbag、sudo apt install python3-rospkg和 之类的方法pip3 install rospkg，但它们没有帮助。

我应该怎么做才能从 Python 3 打开 rosbag 文件？

这是调用后的输出pip3 install rospkg：
