# FastH3 on one DGX Spark (one GB10). Install: docs/getting_started/installation/spark.md
|
|
#
|
|
# GB10 has no FA4 / sm_100a VSA kernel. Keep the env prefix below, or pass
|
|
# equivalent CLI flags on examples/inference/basic/basic_fasth3.py
|
|
# (`--vsa-kernel triton --no-fa4 --num-gpus 1`).
|
|
#
|
|
# request.sampling below is an example, not a required recipe. Change height,
|
|
# width, num_frames, num_inference_steps, seed, and prompt. Legal H3 frame
|
|
# counts are 17n+5, max 345 (15 s). Native 16:9 sizes include 832x480 and
|
|
# 1344x768. 1024x576 is a common recipe-matched 16:9.
