See the guide's L20 commands for the `/data1/yfzx/wangx` paths.
For **encoder-only A / V / AV**, without Thinker states, see
[the encoder-only comparison guide](docs/ego4d_encoder_only.md).
`prepare_encoder_only_features.py` packs complete local vectors and validity
bits on CPU; `run_ego4d_encoder_only.py` trains/evaluates four-epoch heads with
no dev set. This native-concatenation baseline is not capacity- or
context-matched to the Thinker baseline.
