在解决了上面两个issue后，按照123页运行后，还是无法启动两个gpu:worker，加一个cpu：PS分布式训练。求问命令行应该如何输入，还是代码的问题。

There are different conventions for virtual environments.
Like creating all the virtual environments on a folder ( "~/virtualenvs/" ),
or naming the virtual environment with a leading dot ( ".../project/path/.venv" ),
right now the virtual environment is created inside the project folder with a default name "venv"

Using colour as a way of conveying information doesn't work for certain kinds of colour-blindness.

• Use icons instead of just colour (test with https://www.toptal.com/designers/colorfilter)
• Ensure that the generated markup that this project controls works with screen readers.

Feature Request

It would be nice to have an example showing how to load a robot from URDF / ROS (robot in meters) and then scale it (for millimeters).

robot = client.load_robot(load_geometry=True)
robot.artist = RobotArtist(robot.model)
robot.scale(1000)

It should also be ensured that scale() can be called before or after setting the artist, and lead to the same result.
