Hi, I meet the error output KeyError: 'pddl_params' when running generate_trajectories.py, as shown in image below:

I was wondering where could be wrong? Thanks!

@wang-sj16, I am not sure what is happening here. Was generate_trajectories.py somehow modified? It looks like this line isn't being called.

@MohitShridhar Hi, I didn't modify the code and the running command is python scripts/generate_trajectories.py --save_path data/new_trajs --in_parallel --debug --num_threads 1

@MohitShridhar found the bug. In this line, it should use import constants rather than import gen.constants as constants, latter will generate a new constants instance with no initilization.

oh thanks @wang-sj16 for investigating this. I'll try it out and merge into master soon.
