DeepSpeed config file not found

When running my DeepSpeed training script with the command deepspeed --num_gpus=0 --model_id google/flan-t5-xxl --dataset_path data --epochs 3 --per_device_train_batch_size 8 --per_device_eval_batch_size 8 --generation_max_length 129 --lr 1e-4 --deepspeed dsconfig.json , I encountered an assertion error with the message assert config != None, "DeepSpeed requires --deepspeed_config to specify configuration file" . What does this error message mean? the configuration path is correct
