I run ./make.sh. inside a docker file. It announced:

However, when run DCNv2, there is an error:

File "/docker/src/lib/tracker/multitracker.py", line 8, in from models.model import create_model, load_model File "/docker/src/lib/models/model.py", line 8, in from .networks.pose_dla_dcn import get_pose_net as get_dla_dcn File "/docker/src/lib/models/networks/pose_dla_dcn.py", line 15, in from .DCNv2_new.dcn_v2 import DCN File "/docker/src/lib/models/networks/DCNv2_new/dcn_v2.py", line 13, in import _ext as _backend ModuleNotFoundError: No module named '_ext'`

Can anyone meet it? Please help me.

Thank you so much.

Hello, When running your docker container, don't forget to make your gpus available by adding --gpus all as an argument to your docker run command. Hope it helps.
