关于mmdet版本问题

[sayoko17]

我安装了2.8.0的mmdet
但在执行
config_file = 配置文件路径
checkpoint_file = 模型路径
model = init_detector(config_file, checkpoint_file, device='cuda:0')
加载模型时，却得到了这样的报错：

Traceback (most recent call last):
File "newtest.py", line 17, in
model = init_detector(config_file, checkpoint_file, device='cuda:0')
File "/home/sxn/data/env/openmmlab/lib/python3.7/site-packages/mmdet/apis/inference.py", line 38, in init_detector

f'{obj_type} is not in the {registry.name} registry')
KeyError: 'alt_gvt_small is not in the backbone registry'

然后gvt.py里确实是有注册成backbone的，不知道如何解决

newtest.py 是不是没有import gvt，所以注册没有？

在init__里面导入后，好像是在文件目录下重新生成，

python setup.py develop

对于mmdetection， pip install就可以
