Issue in enviornment setup

[rishavb123]

I followed the setup instructions in the README and when I tried to run the train script with:
python train.py --configs defaults lexa_temporal --task dmc_walker_walk --logdir ~/logdir/lexa_temporal_walker

I got the following error:

Traceback (most recent call last):
  File "train.py", line 9, in <module>
    from dreamer import Dreamer, setup_dreamer, create_envs, count_steps, make_dataset, parse_dreamer_args

But I was able to fix this using these two commands:
rm ~/miniconda3/envs/lexa/bin/../lib/libstdc++.so.6
cp /usr/lib/x86_64-linux-gnu/libstdc++.so.6 ~/miniconda3/envs/lexa/bin/../lib/

But after that, when I ran the train script again using the same command as above I got this error:

Traceback (most recent call last):
  File "train.py", line 9, in <module>
    from dreamer import Dreamer, setup_dreamer, create_envs, count_steps, make_dataset, parse_dreamer_args

  File "/home/ei-lab/rbhagat8/lexa-benchmark/metaworld/__init__.py", line 7, in <module>
    import metaworld.envs.mujoco.env_dict as _env_dict
ModuleNotFoundError: No module named 'metaworld.envs.mujoco'

I tried reinstalling metaworld with pip install metaworld but it still results in the same error. Any advice?

Make sure you are following the setup instructions. Do not pip install metaworld; you have to use the version we provide. Since the mujoco module is present in the repo, this error can't happen if you set up the repo correctly.

[rishavb123]

The error came up before I pip installed metaworld as well.

I ran
conda env create -f environment.yml
conda activate lexa

and then

export PYTHONPATH=~/rbhagat8/lexa/lexa:/home/ei-lab/rbhagat8/lexa-benchmark
export MUJOCO_RENDERER=egl; export MUJOCO_GL=egl
export MJLIB_PATH=~/.mujoco/mujoco200/bin/libmujoco200.so
export MJKEY_PATH=~/.mujoco/mjkey.txt

and then
rm ~/miniconda3/envs/lexa/bin/../lib/libstdc++.so.6
cp /usr/lib/x86_64-linux-gnu/libstdc++.so.6 ~/miniconda3/envs/lexa/bin/../lib/

to fix the first error above.

After this I used
python train.py --configs defaults lexa_temporal --task dmc_walker_walk --logdir ~/logdir/lexa_temporal_walker
to run the train script and got the meta world error

[orybkin]

Can you verify that metaworld.envs.mujoco is present? Since it is in the repo you should have it as well.

[rishavb123]

The mujoco folder isn't in the lexa-benchmark repo. I just tried recloning it and got this message:

fatal: packed object 9349e92fd000b33e00fbdcc856d2d7528b17a8ba (stored in ~/lexa-benchmark/.git/objects/pack/pack-3e9847d724f9e099ec4bbe6e66d9c03bcb04bdb9.pack) is corrupt
warning: Clone succeeded, but checkout failed.
You can inspect what was checked out with 'git status'
and retry with 'git restore --source=HEAD :/'

I cannot replicate this problem. You can manually download a zip from github.

[rishavb123]

Will do! I'll give that a try and let you know. Thanks for all the help!

[rishavb123]

Awesome that seemed to fix this problem, thanks! Now, just debugging some cudnn stuff to get the repo running.
