raise _exceptions.DuplicateFlagError.from_flag

Hi, I try to train but using this cmd command:

main.py --train_dir=../imgs/train/ --val_dir=../imgs/val/ --image_height=60 --image_width=180 --image_channel=1 --out_channels=64 --num_hidden=128 --batch_size=128 --log_dir=./log/train --num_gpus=1 -mode=train

But got this error:

absl.flags._exceptions.DuplicateFlagError: The flag 'log_dir' is defined twice. First from absl.logging, Second from utils.  Description from first occurrence: directory to write logfiles into

How can it be fixed?
