Ilegal Instruction when testing the installation code

[Escoastin]

Having followed all the installation instructions at myosuite.readthedocs.io/en/latest/install.html ,
I executed the following code

as follows:

and I get the following error message:

After consulting ChatGPT, it recommended the following code to verify whether the computer architecture is compatible:

I get this:

Does anyone know how to proceed because it is very difficult to determine.

hi @Escoastin , can you add which operating system and python version are you using?

[Escoastin]

I'm using windows 10 Pro with Ubuntu installed on it (I downloaded it yesterday because I was struggling with the installation process on Windows)

Here is the OS according to Linux

and python

[Vittorio-Caggiano]

I see you use python 3.12... we never tested it with that version. Can you downgrade from 3.8 to 3.10?

[Escoastin]

So here is another issue. I tried to downgrade but since I have to install Miniconda to activate the environment, it automatically updates it to Python3.12.4, which is confusing because I would like to use Python3.12 as you've suggested. Any way to get around this loop?

[Vittorio-Caggiano]

did you try to create an environment with a specific python version with

conda create --name myosuite python=3.8
conda activate myosuite

[Escoastin]

Yes I did this and my version is now python 3.8.19
When I attempt to run the following test, I get the following error messages:

And then for this one, I get:

[Escoastin]

So I've ditched the Linux thing to work on my Miniconda powershell on Windows. Looks like I'm not getting the illegal instruction thing and that it seems to generate something without the screen popping up:

I would think its a case of finding out why the mujoco screen isn't displaying the test, right?

[Vittorio-Caggiano]

Hi @Escoastin those tests are only to verify that all the environments are available and functioning correctly. In order to visualize the task you need to use the commands below:

from myosuite.utils import gym
env = gym.make('myoElbowPose1D6MRandom-v0')
env.reset()
for _ in range(1000):
  env.mj_render()
  env.step(env.action_space.sample()) # take a random action
env.close()

there are also colabs and tutorials

[Escoastin]

Okay so I've finally fixed the display issue and am doing the visualizations of the task as you suggested. For the code above, do I type it into MyoSuite environment on Python in the terminal or I execute it elsewhere? (I am new to this so I'm still getting used to everything)

[Vittorio-Caggiano]

That code is for a python terminal. We need to make it more clear in the Readme.

[Escoastin]

Okay everything seems to work properly. One last question concerning the terminal part: Once I finish the for loop code, how do I enter the env.close() part in the terminal without it running? Or is that just how it works?

[Vittorio-Caggiano]

what do you mean? env.close() is run within the python terminal after the for loop

[Escoastin]

Okay no issue. I've encountered a new problem which is annoying because it feels as if everytime I progress there's something that pulls me back. I was able to run the tests perfectly 3 days ago but now after wanting to run this code:

It doesn't even go past the gym part. It takes me back to root:

I verified the installation of the requirements and they are all satisfied.

[Vittorio-Caggiano]

this should not be happening. It is quite challenging for us to debug what is happening. We run tests against windows installation and everything should be working. Can you try for now to use Colabs for now and post more info when you manage to do some more troubleshooting?

[Escoastin]

Okay I will use Colabs until I find a solution. Thank you very much!
