Debug

Known issues

gotchammengine-lite intentionally excludes torch and heavy dependencies. If you need torch (e.g., Runner, optimizers), use the full mmengine package instead (pip install mmengine).

fix

Install mmengine instead: pip install mmengine

affects: all

breakingFrom mmengine v0.10.0+, the import path for many utilities changed. Previously, some symbols were importable directly from mmengine; now they require submodule imports.

fix

Use from mmengine.config import Config instead of from mmengine import Config

affects: >=0.10.0

gotchaThe lite version is not a drop-in replacement for mmengine. Features like Runner, optimizers, and checkpointing require torch and are not available in mmengine-lite.

fix

Check the official docs to see which modules are available in the lite version.
