Updating gym to gymnasium and cleaning some imports

[mikelitu]

Hello,

I am working a lot with Sofa in the last few years for my PhD and I have found this repository as @ScheiklP mentioned one code snapshot from it when I was struggling with a grasping simulation. I have to say that this repository is really impressive and I would be really interested to use some of the environments to train some DNN for my PhD and add some extra functionalities along with my work.

However, I came across some problem when trying to install the python package on my computer. I found the error was coming from the Gym package. As I could read at the official repository from OpenAI about Gym, they stopped maintainance on this repository on 2021. The development was moved to Gymnasium and now the recommended form of use is import gymnasium as gym. I think it will be good for new users to have this updated on the main branch. Do you want me to submit a pull request with the necessary changes?

Regards,
Mikel

Hi @mikelitu,
thanks a lot for your kind words! :)

I actually have a local branch where I already updated to gymnasium.
I just did not have the time yet to properly review and push it.

I will try to do that in the coming weeks and would be very grateful, if you could review the PR. Would you be interested in that?

Cheers,
Paul

Hi @mikelitu,
from a first check, that went easier than expected.
Could you head over to the PR and give it a test drive?

Cheers,
Paul
