Train DBNetpp with ConvNeXt backbone

[FranziSchmitt]

Hi,
I've recently upgraded mmocr from version 0.6.2 to 1.x.
In the previous version, I was able to train DBNetpp using a convnext backbone. With mmocr 1.x, I'm getting compatibility errors with mmcls and mmcv versions. I've tried a couple of variations and versions of mmcls, mmcv, and mmcv-full but all of them are resulting in some kind of incompatibility message.

Training with the resnet backbone is not an option for me.

How can I get training of dbnetpp running with the convnext backbone?
Thanks!

MMOCR 1.0 is a part of OpenMMLab 2.0 - and all its OpenMMLab-series dependencies need to be upgraded. A suggested practice is to create a new virtual environment and install everything following the Installation Guide. Similarly, you will have to switch mmclassicifaion to 1.x branch for compatibility.

For more information, you can read the migration guide.
