PolarMask is not in the models registry

This problem arises when I will PolarMask Copy your model and configuration files to the newly installed mmdetection What happens during training .

First of all, the main reason , Because PYTHONPATH There is no... In the environment variable mmdetection Under the build A subdirectory of ( Take a closer look at the installation prompts and you will be able to solve the problem )
resolvent ：

1. uninstall mmdetection( Or you can not uninstall ？ I didn't try )

2. stay ~/.bashrc Write in
   ( Change the path to your own )

export PYTHONPATH="/mnt/h/Experiments/Code/mmdetection-2.21.0/build/bdist.linux-x86_64/egg/:$PYTHONPATH"

3. Enable environment variables

source ~/.bashrc

5. reinstall mmdetection

python setup.py install develop

The solution to my problem is like this , Next, the hardware performance is not enough , The problem of adding money .
ImportError: cannot import name ‘force_fp32’
from mmdetection1 Migrate to mmdetection2
These two functions need to be imported like this

from mmcv.runner import auto_fp16, force_fp32

PolarMask: FPN: init() got an unexpected keyword argument ‘extra_convs_on_inputs’
This is mmdetection Kind of , Should put the extra_convs_on_inputs and add_extra_convs These two parameters are unified ,extra_convs_on_inputs=False Should be equal to direct
add_extra_convs=True, Specific to see fpn.py The source and
