[Berry-Wu]

my version is：
Package Version Source

---

mmcv 2.0.1 https://github.com/open-mmlab/mmcv
mmengine 0.8.4 https://github.com/open-mmlab/mmengine
mmpose 1.1.0 https://github.com/open-mmlab/mmpose
And I find that there is no constant_init in mmcv/cnn. What should I modify?

[sidiangongyuan]

I have the same question about this. Maybe it's a problem about the version. Have you solved it?

[matanPercepto]

I have the same issue, probably a change made by the move to mmcv 2, but can't find where it was moved to.
Any luck?

[sidiangongyuan]

Yes, I have solved this problem. I just change version of my mmcv. Some package has been moved to mmengine

This will solve the problem "from mmengine.model import (constant_init, kaiming_init)"
