# In this example, we show how to train SimCSE using multiple GPU cards and PyTorch's distributed data parallel on supervised NLI dataset.

# Set how many GPUs to use
NUM_GPU=4

# Randomly set a port number
# If you encounter "address already used" error, just run again or manually set an available port id.
PORT_ID=$(expr $RANDOM + 1000)

# Allow multiple threads
export OMP_NUM_THREADS=8

# Use distributed data parallel
# If you only want to use one card, uncomment the following line and comment the line with "torch.distributed.launch"
# python train.py \
