how can I use metadrive environment?

[hyoonsoo]

I want to use meta drive environment.
but It shows the same error: "No module named 'metadrive.envs'"
I'm using

gym 0.20.0
metadrive 1.4.9.1
metadrive-simulator 0.2.3 (as written in the document)

Can you give me some help? Thank you.

Hi,

I recommend you reproduce this kind of error in your python console.

1. switch to your python virtual environment
2. type pip show metadrive to check the installation
3. if you pass step 2, enter into the python console.
4. in console, type import metadrive or import metadrive.envs to see the full error trace.

Any further question is welcome.

You can reopen this issue if you have further questions.
