i want to know how to run the .sh without slurm to segmentation, because the slurm is hard to use.

单机单卡、单机多卡、不使用slurm实现语义分割。
1 数据集导入需要在semantic_segmentation文件夹下。

2 batch_size参数修改,在semantic_segmentation/configs/base/datasets/ade20k_sfpn.py中,修改为samples_per_gpu=8, workers_per_gpu=8即可。

3 lr和iters参数修改,在semantic_segmentation/configs/ade20k/sfpn.biformer_small.py中,根据经验公式gpusbatchsizeiters=定值,lr=定值(gpus*batchsize)修改lr和iters即可。

4 多卡训练参数修改,只需修改slurm.sh文件即可。以下是我没有使用slurm的多卡训练脚本。
#!/usr/bin/env bash
PARTITION=mediasuper
NOW=$(date '+%m-%d-%H:%M:%S')
JOB_NAME=${MODEL}

CONFIG_DIR=configs/ade20k
MODEL=sfpn.biformer_small
CKPT=pretrained/biformer_small_best.pth
CONFIG=${CONFIG_DIR}/${MODEL}.py
OUTPUT_DIR=../outputs/seg
WORK_DIR=${OUTPUT_DIR}/${MODEL}/${NOW}
mkdir -p ${WORK_DIR}

PYTHONPATH="$(dirname $0)/..":$PYTHONPATH \

export CUDA_VISIBLE_DEVICES=0,1,2,3 # 暴露GPU编号
torchrun
--nproc_per_node=4 \ # 这个就是GPU数量
--master_port=29501
train.py --config=${CONFIG}
--launcher="pytorch" \ # 这里不使用slurm启动器
--work-dir=${WORK_DIR}
--options model.pretrained=${CKPT}
&> ${WORK_DIR}/train.${JOB_NAME}.log &

你好请问单机单卡也是这么设置的吗?

把export CUDA_VISIBLE_DEVICES=0,1,2,3 # 暴露GPU编号 改成0
把--nproc_per_node=4 \ # 这个就是GPU数量 改成1
就行了

还要导入一下ckpt权重文件,在作者的readme里面有,新建文件夹pretrained,下载到里面即可。
