UnregisteredEnv problem in SAR tutorial Step 1.2

[Ming-Start]

I followed the tutorial and completed many processes, but when I ran the code in step 1.2 ：

SAR_RL(env_name=f'myoLeg{new_terrain}TerrainWalk-v0', policy_name='SAR-RL', timesteps=2.5e6, seed='0', ica=ica, pca=pca, normalizer=normalizer, phi=.66, syn_nosyn=False)

the following error occurred：

---

KeyError Traceback (most recent call last)
File ~/anaconda3/envs/SAR/lib/python3.8/site-packages/gym/envs/registration.py:132, in EnvRegistry.spec(self, path)
131 try:
--> 132 return self.env_specs[id]
133 except KeyError:
134 # Parse the env name and check to see if it matches the non-version
135 # part of a valid env (could also check the exact number here)

KeyError: 'myoLegStairsTerrainWalk-v0'

During handling of the above exception, another exception occurred:

Hi @Ming-Start ,

which version of MyoSuite did you install? how did you install it?

Directly with

pip install -U myosuite

or, by cloning the repo with

git clone --recursive https://github.com/facebookresearch/myosuite.git

[Ming-Start]

I download Myosuite2.0

and I use this way to download it

git clone --recursive https://github.com/facebookresearch/myosuite.git

The correct name is myoLegStairTerrainWalk-v0, not myoLegStairsTerrainWalk-v0. Your code should work once you correct this! I will push an update to the notebook with this error fixed
