更改Detectron2内置数据集的路径

Question

I want to change the default path of builtin PASCAL VOC Dataset in Detectron2.

According to the documentation,

You can set the location for builtin datasets by export DETECTRON2_DATASETS=/path/to/datasets

I'm unable to understand where to place the above statement.

Any help would be appreciated.

Thanks

I met the same problem and the solution is simple following this .

First, in your terminal, import your customized dataset directory as env variable like this

My@Host:/MaskFormer-main$ export DETECTRON2_DATASETS="/public/COCO2017"

Then, running your scripts of the maskformer

My@Host:/MaskFormer-main$ python train_net.py --num-gpus 1  --config-file xxxxxxx
