pretrained models

[st2yang]

Hi,

Thanks for your great work! And I am trying to reproduce/benchmark your results. Would you mind sharing the pre-trained models for evaluation?

Thanks,
Yang

Hi, sorry, I don't have the pre-trained weights anymore. I had to clean a bunch of stuff off my hard drive awhile ago.

[st2yang]

Sure, I'll try to train the models on my own.

I tried to install the environment properly but encountered one issue while running the scripts. Can you help a little? I am wondering how you set up the bashrc to run the scripts?

I can run with standard mujoco/gym environments. But when I run your scripts, it raises the following errors. It looks like the issue here mujoco issue. But I haven't properly set up my bashrc so far. I also attached my bashrc below.

Thanks,
Yang

[st2yang]

I managed to set up bashrc to run the code.

[madhan001]

@st2yang what were the exact changes you did to bashrc to fix this error?

[st2yang]

@madhan001 This is my modified bashrc

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/homes/yangyang/.mujoco/mujoco200/bin
export MUJOCO_KEY_PATH=/homes/yangyang/.mujoco${MUJOCO_KEY_PATH}
export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libGLEW.so
