Intro

Hi!

I am a researcher, I use MuJoCo to run simulations for LeRobot.

My setup

I used a fresh conda environment on MacOs 15.6.1 (24G90), Macbook Pro M1. Basically the following:

conda create env conda activate env conda install python pip install mujoco

Resulting env:

What's happening? What did you expect?

I run

(lerobot4) brickerino@akuznetsov-mbp:~/src/lerobot$ mjpython --version
Python 3.13.7
Segmentation fault: 11

and I get a segmentation fault. Regular python works ok.

(lerobot4) brickerino@akuznetsov-mbp:~/src/lerobot$ python --version
Python 3.13.7

I use mjpython because I need launch_passive on MacOs.

Steps for reproduction

Build the env, run the command.

Minimal model for reproduction

No model required.

Code required for reproduction

mjpython --version

Basically I tried to run some examples from the LeRobot repo. The example was behaving strangely and would crash sometimes. After some debugging I found this minimal example.

I tried downgrading the package, but I get 'RuntimeError: MUJOCO_PATH environment variable is not set' error. We can go deeper into this one, but I think it's not that relevant because it's not the freshest version.

Install mujoco

pip install mujoco

Download MuJoCo binaries (if not already)

For macOS/Linux, typical path is ~/.mujoco/mujoco210

Set environment variable in your shell config

export MUJOCO_PATH=$HOME/.mujoco/mujoco210

Would you be able to give me the stack trace for the segfault? It should be available in Console right after you encounter the crash.

export MUJOCO_PATH=$HOME/.mujoco/mujoco210

The binaries should be included in the package, right? The instruction for 3.2 doesn't differ from the latest version, there is nothing there about downloading binaries separately. And I'm reporting this problem/bug, not looking for a way to make it work.

There's nothing in the console, but today I tried it and a Macos 'Problem reported' window opened (I don't remember it doing that before). Will this be enough or I should try and get something with GDB? (I tried but so far I don't understand how to do it).

Sorry, just got around to repro this issue.

I think the --version crash is a red herring. Can you please post the crash that occurs when you try to run your actual code?

saran-t avatar Oct 21 '25 17:10 saran-t

Hi!

I think the --version crash is a red herring.

Well I tried to find a minimal example that didn't include other layers of software on top of mujoco. I was playing around with https://github.com/huggingface/gym-hil and moved on to a bit different problem since, so I don't have a bug example in a full pipeline right now.
