Start with the problem in front of you.

Check import, native-library loading and file decoding in that order. Installing FFmpeg does not establish that every dependency of SoundFile is available.

Separate the library import from architecture support and the identity of the weights.

Separate missing libraries, database access and migration state without deleting the database.

A node imports the library, chooses an implementation and may then obtain pretrained weights. Determine which stage failed instead of treating every message as a missing package.

Two nodes can require different timm versions. Map the consumers and their supported ranges before deciding whether one environment can serve both.

Locate the failing stage before changing Transformers, model files or network settings.

An AttributeError in a color node may concern an old mapping, not a missing module. Identify the exception before choosing a package repair.

The named Python module can depend on another missing or incompatible runtime library. Native import failure is different from a top-level Python package simply being absent.
