[Errno 111] Connection refused

[imruljubair]

I am trying to run the code on AWS SageMaker StudioLab. But I am getting error "ConnectionRefusedError: [Errno 111] Connection refused". The message is shown below. Can anyone please help?

python scripts/segmentation_train.py --data_name ISIC --data_dir input data direction --out_dir output data direction --image_size 256 --num_channels 128 --class_cond False --num_res_blocks 2 --num_heads 1 --learn_sigma True --use_scale_shift_norm False --attention_resolutions 16 --diffusion_steps 1000 --noise_schedule linear --rescale_learned_sigmas False --rescale_timesteps False --lr 1e-4 --batch_size 8
