first step:
Open the folder "/mnt/sdb1/fenghaixia/deeplabv3-plus-pytorch-main/VOCdevkit/VOC2007/ImageSets/JPEGImages" that I need to connect to, right click on this folder and select "Open in Terminal"
Step two:
ln -s '/mnt/sdb2/fenghaixia/BuildFormer/data/whubuilding/train/images' JPEGImages
Note: Absolute paths need to be enclosed in quotation marks
ln -s [source file or directory] [target file or directory]
