How to train quickly after training error

Hello I asked a question when I was running this command
python train_full_pipeline.py -s /root/SuGaR/scene3/ -r "dn_consistency" --high_poly True  --export_obj True

I got an error saying that I didn't install the opengl library. Should I run this command line again after reinstalling it? It seems that I need to retrain it
Looking forward to your reply. It is very important to me
