Run demo error.

[Yang-Yefeng]

I occured an error when I was running the demo in ReadME.md.
I was running: ./create_fig6.sh

The error:

Traceback (most recent call last):
File "./gp_mpc_experiment.py", line 197, in
plot_xz_comparison_diag_constraint(prior_run, run, 1)
File "./gp_mpc_experiment.py", line 27, in plot_xz_comparison_diag_constraint
ax = plot_2D_comparison_with_prior(state_inds, prior_run, run, goal, init_ind, dir=dir)

@Yang-Yefeng are you running safe-control-gym in its own dedicated condo environment?
@adamhall is this an error you are familiar with>

Hi @Yang-Yefeng,
Your issue seems very similar to issue #95. Have you taken a look there?
Also, could you list the python packages you have installed and their versions running something like

pip3 list or conda list.

Thanks!
