接口对照表

由于 MMCV v1.x 升级到 MMCV v2.x 时移除了 mmcv.fileio，mmcv.runner，mmcv.parallel，mmcv.engine，mmcv.device 模块，以及 mmcv.utils 中的所有类和大部分函数，分别删除于 PR #2179，PR #2216，PR #2217。因此我们提供了如下的接口对照表，以便于大家快速查找迁移后的接口。

相关讨论

• Remove runner, parallel, engine and device
• ImportError: cannot import name 'is_list_of' from 'mmcv.utils'
• Could not find the files in MMengine which are removed in MMCV_v2x parallel. example, for DataContainer
• mmcv.cnn.bricks.registry
• Replace mmcv's function and modules imported with mmengine's
