OSError: [Errno 12] Cannot allocate memory (My graphics card is 3080,)

Hi, I downloaded the Charades dataset and tried to train the dataset with the command:
> python tools/run_net.py --cfg configs/Charades/SLOWFAST_16x8_R50.yaml

BATCH_SIZE: 1
DATA_LOADER:
NUM_WORKERS: 1
PIN_MEMORY: True
NUM_GPUS: 1
NUM_SHARDS: 1
RNG_SEED: 0

I got the following error,

OSError: [Errno 12] Cannot allocate memory

I wonder if you could point out what is going wrong.

Many Thanks!

And,please tell me that what is the minimum video memory,RAM,and configuration required for slowfast code?
My graphics card is 3080,is the configuration not enough?

Many Thanks!

Start at tools/run_net.py and tools/train_net.py, then inspect the Charades loader construction reported in charades.py and the PyTorch DataLoader traceback. Reproduce with the shown configuration, especially NUM_WORKERS: 1 and PIN_MEMORY: True, and determine whether the failure is host-memory allocation. Done means documenting a verified configuration or concrete project change that avoids the error.
