An adapter that trains a subset of the wrapped linears (Pika skips the
AdaLN projections) logged one warning per layer, about 200 per run.
Log one summary with the count and a few names.
Add Pika H3 Flex (MiniMax-H3 plus the released fl2va/ref2va rank-128 adapters) as a FastVideo model family: registry/config/presets, bucket geometry with tiered reference sizing, automatic adapter selection and manifest validation, the fixed six-forward re-noise sampler, T2VA/I2VA/L2VA/FL2VA/Ref2VA pipeline support, an example, docs, and CPU unit tests.
GPU end-to-end validation is still pending. This change does not add PDD, VSA, or new kernel paths.
Ray sets CUDA_VISIBLE_DEVICES of each GPU actor to the GPU of that actor. The
import of fastvideo initializes CUDA, so the executor cannot change the device
list later. On a node with more than one GPU, each worker after the first worker
failed with "invalid device ordinal".
On NVIDIA GPUs, each worker actor now keeps the device list of its raylet
(RAY_EXPERIMENTAL_NOSET_CUDA_VISIBLE_DEVICES=1). Each worker uses the position of
its GPU in that list as its local rank. The safetensors loader now reads each
file on node-group rank 0, which is the rank that sends the broadcast.
