Please tell me the solution, thanks

Try this: pip install mmcv-full==latest+torch1.5.0+cu101 -f https://openmmlab.oss-accelerate.aliyuncs.com/mmcv/dist/index.html

[hellock]

The version you used may be too old.

[dhananjayd232]

pip install mmcv-full==latest+torch1.5.0+cu101 -f https://openmmlab.oss-accelerate.aliyuncs.com/mmcv/dist/index.html

still getting same issue as mentioned

[danielefundaro]

I have the same problem too.
When I run the command from mmdet.models import build_detector I got the error below:

File "/usr/src/app/mmdetection/mmdet/models/__init__.py", line 3, in <module>
    from .bbox_heads import *  # noqa: F401,F403

    from mmcv.cnn.weight_init import normal_init, xavier_init
ModuleNotFoundError: No module named 'mmcv.cnn.weight_init'

This is what I have from the command python mmdetection/mmdet/utils/collect_env.py:

How did you solve it? Please help.

[kaizhan]

all you need to do is
pip install mmcv==0.4.3

[Armstrong-lsw]

all you need to do is
pip install mmcv==0.4.3

god like!

[PrithwishChakraborty]

even after installing mmcv==0.4.3 getting the same error

[dav-ell]

Same. mmcv is on 2.0.0 now, also.

[KaneiGi]

change the code
from mmcv.cnn.weight_init
to mmcv.cnn

[wuchengyu123]

Actually pip install mmcv==1.0.2 will fix this. I tried for accidently and succeed.

[WH0226]

from mmengine.model import constant_init

[maxiuw]

if you're using xavier_init it's in from mmengine.model import xavier_init instead :)
