I don't know why it comes up, anyone could help me? Thx!

It appears that we accidentally require mapper argument to be explicit, i.e. it must be build_detection_train_loader(cfg, mapper=mapper). We will revert this requirement.

Thx for your help, it worked, but I met another problem.

Traceback (most recent call last): File "tools/train_net.py", line 237, in launch( File "/root/anaconda3/lib/python3.8/site-packages/detectron2/engine/launch.py", line 62, in launch main_func(*args) File "tools/train_net.py", line 225, in main trainer = Trainer(cfg) File "tools/train_net.py", line 69, in init super(DefaultTrainer, self).init(model, data_loader, optimizer) TypeError: init() takes 1 positional argument but 4 were given

I thought may be another version issue, how could I fix it?

I can't see your code so I cannot answer this one. There is an issue template that asks for enough details.

I'm using AdelaiDet training code, below link is the code I used. https://github.com/aim-uofa/AdelaiDet/blob/master/tools/train_net.py exception happened in line 69.
