why can't i load the data?

Thanks for your great contribution.
When I typed the command, it didn't respond and only show this

The command i typed is "python main_nerf.py data/custom --workspace trial_nerf_custom -O --gui --scale 0.8 --bound 1.0 --dt_gamma 0.02"
I can successfully run it before, it is a suddenly problem.I really hope and appreciate for your help.
