Unable to run experiments

[tsagkas]

Intro

Thank you very much for sharing your code. However, I have a lot of issues with installing eai-vc and I was unable to run the experiments. To help you read this GH Issue faster, I have divided it into two parts.

• First, I will share the issues I had with the installation.
• Second, I will present the problems that came up when running the experiments.

I apologize in advance if I missed something in either the mujoco or the hydra part of the code, since these are tools I have never utilized before.

Some additional info about my setup:

• Ubuntu 22.04
• CUDA 12.1
• python 3.8.18

EAI-VC Installation Issues

To install eai-vc I followed the process described at installation.md to the letter (and have repeated the process a few times now to make sure I did not miss anything). Verifying my installation with the provided pytest, I get two major errors:

(1) dmc2gym version problem

AttributeError: 'MjModel' object has no attribute 'eq_active'

According to other relevant issues I found online (e.g., here), this can be solved either by downgrading mujoco to 2.3.* or upgrading dm_control from 1.0.5 to 1.0.16. Even though I tried both (without luck), let's consider for now that I follow the latter path, so that I don't mess with the other tasks, which might not like mujoco 2.3.*.

(2) mjrl, mj_envs incompatible with cython 3

Error compiling Cython file:
------------------------------------------------------------
...
    See c_warning_callback, which is the C wrapper to the user defined function
    '''
    global py_warning_callback
    global mju_user_warning
    py_warning_callback = warn
    mju_user_warning = c_warning_callback
                       ^
------------------------------------------------------------

The problem shown in the picture below, can be solved by downgrading cython pip install "cython<3" as indicated by various sources (e.g., here)

Running the PyTest

With the changes above I get to successfully run the pytests, however, a few warnings remain. Fixing these can easily become a rabbit hole, where upgrading something breaks something else. At least, now the pytest runs.

EAI-VC Experiments Issues

After that, I try running the launch_all_jobs.sh, which is unsuccessful. To avoid pasting another long screenshot, here's the result from running just python hydra_launcher.py --config-name Metaworld_BC_config.yaml --multirun hydra/launcher=local \ wandb.project=metaworld_test wandb.entity=cortexbench \ env=hammer-v2-goal-observable \ seed=100 embedding=vc1_vitb, which leads to the same errors:

Question

Am I doing something wrong in the installation? Do I need to run the experiments in a different way?

Thanks in advance and I apologize for such a long detailed issue!

Hi, thanks for your effort! I've encountered the same experiment issue as yours. Have you solved it?
