1. Can you support pytorch<2.0 for training? Computers do not support cuda for 11.8
   2 What are the differences between train experiment files and train? Is there a problem with the train file code? train experiment file I can use cpu to train, train will report error.

I'll have a cleaning of the files & readme planned. Was quick release. Not sure if I get to it within this month.

1. PyTorch < 2.0 is in general possible and the first versions worked on it. Currently cannot estimate what needs to be changed to make the versions compatible again and what might break. I mostly worked with cuda 11.7.

2. The train.py file is set up to work with a single settings.json file and was build more with DeepSpeed in mind, the train_experiments.py to works with several input files from the experiments folder and is more recent.
   I'm planning to unify these.

train.py file has been fixed thank you. The --logname parameter was not optional like intended.
