IndexError: too many indices for tensor of dimension 2

Hi,

I am trying to run the train_chart.py with lien data. I am getting the below error-

total parameters: 198592138 start prefetching data... shuffling indices... setting learning rate to: 0.00025 training start...

Can you provide a solution?
