I have doubts about the A3C algorithm: How to perform Asynchronous for carla

[robot-xyh]

Hi，
In the A3C algorithm, you set "num_workers": 3. Does this mean I have to run three carla environments? The official document states that when "num_workers">0, the gym environment will be automatically vectorized. Can carla that inherit the gym environment also be automatically vectorized?
I'm very much obliged to you
