Unable to run mbppo_lagrangian.py

Hi @akjayant ,

I followed the installation pipeline from the README.md but I get the following conflicts when running python3.8 mbppo_lagrangian.py --exp_name="test_1" --seed=0 --env="Safexp-PointGoal2-v0" --beta=0.02:

ValueError: numpy.ndarray size changed, may indicate binary incompatibility. Expected 96 from C header, got 88 from PyObject

It seems to be related to the numpy version required by the different packages. I am currently trying to run using numpy==1.21.4. Would it be possible to provide:

1. The commit id of the mujoco-py repository or the version of the mujoco-py package used to run the script
2. The commit if of the safety_gym repository used to run the script

@chrismartel were you able to fix the issue?

I'm also facing this error.
distutils.errors.CompileError: command '/home/rahul/anaconda3/envs/mbppol/bin/gcc' failed with exit code 1
