RuntimeError: CUDA out of memory

[Sei2112]

hello there!
I was running the UCF101_3DCNN.py in pycharm, and this issue showed up:
RuntimeError: CUDA out of memory. Tried to allocate 1.19 GiB (GPU 0; 6.00 GiB total capacity; 3.60 GiB already allocated; 738.91 MiB free; 3.60 GiB reserved in total by PyTorch)
I changed the batch size to 1 and it disappeared. but I guess it is not a proper way to solve the problem. hope someone could offer some suggestion.

What kind of GPU do you have ?
Did you try to reduce the image size and make it square (height=weight) ?

thanks for your help! I reduced the images to 128*128, now I can set batch size to 16 (if higher than 16 it still goes wrong)

It depends on your GPU and the C3D implementation. How many parameters are you training ?

I have same problem @MounirB . I use my own dataset and set begin_frame = 1,end_frame = 500,size = 256,342,number of classes = 5.
But occur cuda out memory. How can I overcome this problem?
Thanks
