Cuda has memory error doing simplest calculation

Hello, I am a college student and pretty new to everything. I just got a Ubuntu laptop and set up CUDA for Pytorch, and it seems CUDA has no memory allocation.Showing me “CUDA error: Out of Memory”

Attached is the screenshot for my gpu.

Please help, thanks!!

(common cause) I think your model allocate the Max GPU memory, you’ll need to reduce batch size.
btw, could you please tell me what model did you train and batch size?
