How to train dataset about train/truck on CPU?

[ChenShujuanCN]

Hi! My environment is as followers:

• Visual Studio 2022
• libtorch-win-shared-with-deps-debug-2.5.1+cpu
• cmake-3.28.3-windows-x86_64
• make-4.4.1-without-guile-w32-bin
• opencv-4.10.0
  I have trained "banana" data successfully, but have some problems when I importing the data about train and truck, which is show in the photo. Can you tell me the reason and the way to solve it?
  
  By the way, I see the instructions about "resume", but don't see this parameter in the code. Is it because I'm a CPU system?
