Exception when running go2_train.py

[tetorea]

Following the instructions on the page https://genesis-world.readthedocs.io/en/latest/user_guide/getting_started/locomotion.html
I get this error when running python examples/locomotion/go2_train.py:

Traceback (most recent call last):
  File "/home/torea/env_genesis/Genesis/examples/locomotion/go2_train.py", line 170, in <module>
    main()
  File "/home/torea/env_genesis/Genesis/examples/locomotion/go2_train.py", line 160, in main
    env = Go2Env(
  File "/home/torea/env_genesis/Genesis/examples/locomotion/go2_env.py", line 42, in __init__
    vis_options=gs.options.VisOptions(rendered_envs_idx=list(range(1))),
  File "/home/torea/env_genesis/lib/python3.10/site-packages/genesis/options/vis.py", line 116, in __init__
    super().__init__(**data)
  File "/home/torea/env_genesis/lib/python3.10/site-packages/genesis/options/options.py", line 27, in __init__
    gs.raise_exception(f"Unrecognized attribute: {key}")

Does this rely on an older version of genesis?

This japanese blog has versions of go2_env.py and go2_train.py that fix this issue:
