load from not working?

[JNaranjo-Alcazar]

Hi community, I have set the load_from flag like:

load_from = '/app/src/mmdetection/checkpoints/mask_rcnn_r50_caffe_fpn_mstrain-poly_3x_coco_bbox_mAP-0.408__segm_mAP-0.37_20200504_163245-42aa3d00.pth'

However, when training, mmdetection starts downloading weights:

2024-10-18 06:36:33,937 - mmcv - INFO - load model from: open-mmlab://detectron2/resnet50_caffe
2024-10-18 06:36:33,937 - mmcv - INFO - load checkpoint from openmmlab path: open-mmlab://detectron2/resnet50_caffe
Downloading: "https://download.openmmlab.com/pretrain/third_party/resnet50_msra-5891d200.pth" to /root/.cache/torch/hub/checkpoints/resnet50_msra-5891d200.pth

Is this behaviour expected?

Thanks in advance
