CUDA run out of memory

[delonixsen]

RuntimeError: CUDA out of memory. Tried to allocate 1.51 GiB (GPU 0; 3.82 GiB total capacity; 1.04 GiB already allocated; 74.38 MiB free; 1.04 GiB reserved in total by PyTorch)

Can someone help me with this problem? since I tried to reduce batch size, and nothing works

GPU : NVIDIA GeForce GTX 1650 4GB

Should I upgrade the Graphics Card?

I got the same error:

RuntimeError: CUDA out of memory. Tried to allocate 1.51 GiB (GPU 0; 3.82 GiB total capacity; 1.04 GiB already allocated; 99.75 MiB free; 1.04 GiB reserved in total by PyTorch) 
If reserved memory is >> allocated memory try setting max_split_size_mb to avoid fragmentation.  See documentation for Memory Management and PYTORCH_CUDA_ALLOC_CONF

The error happened when I ran:
./experiments/scripts/demo.sh

GPU : NVIDIA Quadro T2000 with Max-Q

I'm using:

• Ubuntu 18.04
• PyTorch 1.10.2
• CUDA 11.3
