A problem on training

PS D:\Project_3DGS\4DGaussians> python train.py -s data/multipleview/input

KeyError: 1

Excuse me ,
When training ,i got the error information above . I think it is the problem about the cam input ,but i could not find the reason,paticularly the meaning of "KeyError: 1".
My input is like this ,could you help me solve this problem

e, why your multiple view dataset only have one camera?
