Can we train or test on single GPU in detection sections?

[nestor0003]

If we want to test detection task, or just use the shell code like 'bash dist_test.sh configs/retinanet_alt_gvt_s_fpn_1x_coco_pvt_setting.py checkpoint_file 1 --eval mAP' ?

Or change the lr? and the number of the worker ?
I'm a beginner of the mmdet framework, please help...
this is the error lines:

We suggest using at least 4 GPUs to train.

We still have some intern offers. If you are interested, please send your CV to chuxiangxiang@meituan.com. Thanks
