Couldn't find lunar Lander v3

[tahirbb]

Hi,
I installed gymnasium ( pip install "gymnasium[all]" ) and tried to run lunar lander getting this error. What I missed here?

~/anaconda3/envs/marlbase/lib/python3.10/site-packages/gymnasium/envs/box2d$ python lunar_lander.py 
Traceback (most recent call last):
  File "/home/thr/anaconda3/envs/marlbase/lib/python3.10/site-packages/gymnasium/envs/box2d/lunar_lander.py", line 884, in <module>

What version of Gymnasium are you using? gymnasium.__version__

Hi,

Python 3.10.16 (main, Dec 11 2024, 16:24:50) [GCC 11.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import gymnasium
>>> print (gymnasium.__version__)
0.29.1

Lunar lander is only on v1.0.0, otherwise use Lunar lander v2
