- 
git clone https://github.com/hao-ai-lab/FastVideo.git
-cd FastVideo

  • Output defaults to outputs/zimage/zimage_turbo.png; pass --output to redirect.
    • -
  • Gated or missing checkpoints: run huggingface-cli login and confirm you accepted the model's license on Hugging Face.

All recipes on this page are Source-backed: their commands, model IDs, and flags were validated against the checked-in FastVideo sources listed above (static validation). No runtime GPU validation is recorded for these recipes, so GPU model fit, memory use, throughput, and runtime duration are Unknown and deliberately not claimed. Runtime buttons show only the GPU counts configured in checked-in sources.

Oracle triage identified the bug in `_img2tokens` rearrange order: FV used `(pT pH pW C)` (spatial-major) but the DiT's `video_embedder` Linear weight was trained on the channel-major `(C pT pH pW)` layout that upstream's `UnfoldNd` (grouped-conv reshape, `unfoldNd/unfold.py:66`) produces. The pipeline parity test imported FV's `build_packed_inputs` for both sides at `test_magi_human_pipeline_parity.py:222`, so it consumed equally-permuted tokens on both sides and reported agreement on garbage. Fixed in `latent_preparation.py:_img2tokens` by changing the einops pattern from `(pT pH pW C)` to `(C pT pH pW)`. Validated end-to-end: `examples/inference/basic/basic_magi_human.py` now produces coherent video matching the prompt (woman on park bench reading a book, green trees).

This let the channel-major-vs-spatial-major bug (OQ-6, Wave 14) sit silent for weeks because both sides agreed on the wrong layout.

Affects only fp32 parity testing, not production. | TRACKED FOLLOW-UP (LOW PRIORITY) | ## Troubleshooting diff --git a/fastvideo/pipelines/basic/turbodiffusion/__init__.py b/fastvideo/pipelines/basic/turbodiffusion/__init__.py deleted file mode 100644 index 0df303a96..000000000 --- a/fastvideo/pipelines/basic/turbodiffusion/__init__.py +++ /dev/null @@ -1,6 +0,0 @@ -from fastvideo.pipelines.basic.turbodiffusion.turbodiffusion_pipeline import ( -

DreamX PRoPE/control adapter now lives in `fastvideo/models/dits/dreamx_world.py`; Wan DiT/config have no DreamX-specific fields or `y_camera` signature. | -| Q003 | Which sampler is in first-PR scope: official default `Flow` only, or also `Flow_Unipc` and `Flow_DPM++`? | orchestrator | Phase 3 | resolved | First PR should support official default `Flow` only. FastVideo FlowMatch scheduler parity is non-skip PASS; optional `Flow_Unipc` and `Flow_DPM++` are out of first-PR scope. | -| Q004 | Which HF token env var should be used if rate limits or gated Wan2.2 base weights require auth? | user | Phase 5 | resolved | No auth was required for the completed local downloads; keep using env var names only if future gated repos require auth. | -| Q005 | Should native FastVideo production code depend on DreamX reference-only packages such as `xfuser` or OpenCV? | user | Phase 3 | resolved | No. These packages may be used only for official reference/local parity setup; native FastVideo integration must remove that runtime requirement. | -| Q006 | Should AR handoff require a full generated long-horizon video in this no-HF-token/no-GPU-budget pass? | user/runtime | pipeline | resolved | A40 long-horizon generation passes with 1005 frames at 64x64/4 steps. AR default SSIM passes locally on A40 and on Modal L40S with a 192x192/81-frame reference.

VAE encode parity passes after raw key mapping and applying the official latent normalization to FastVideo output. | -| I007 | quality | pipeline_ti2v | medium | Real image-path TI2V smoke initially failed when `vae_cpu_offload=True` because DenoisingStage encoded the first frame while the VAE weights remained on CPU. | DreamX SSIM first run failed with `RuntimeError: Input type (torch.cuda.FloatTensor) and weight type (torch.FloatTensor) should be the same` at `fastvideo/pipelines/stages/denoising.py` VAE encode. | pipeline | resolved | DenoisingStage now moves the VAE to `local_device` before TI2V first-frame encode; image-path pipeline smoke and DreamX SSIM both pass. | -| I008 | quality | ssim_helper | high | SSIM helper could compare against a stale generated base MP4 when a rerun saved the new video as `_1.mp4`. | Existing generated outputs made AR reference seeding appear to pass before a fresh generated-vs-reference compare. | quality | resolved | `run_text_to_video_similarity_test` and `run_image_to_video_similarity_test` now remove the stale generated base MP4 before generation. A40 and Modal L40S AR SSIM were rerun after the fix. | -| I009 | quality | ar_denoising | high | AR denoising added CUDA noise without using the request seed when the original generator was CPU-backed. | Fresh reruns against old AR references produced mean SSIM near 0.05. | pipeline | resolved | `DreamXWorldARCausalDenoisingStage` now derives a device-local generator from the request seed for AR noise.

The 5B-Cam default test uses the workspace converted model root, `TORCH_SDPA`, a deterministic generated conditioning image, 9 frames, 1 denoise step, seed 1024, and min SSIM 0.98. A local A40 reference was seeded under `fastvideo/tests/ssim/reference_videos/default/A40_reference_videos/DreamX-World-5B-Cam/TORCH_SDPA/`, and the test passed non-skip locally on 2026-07-01. The AR default test uses `/tmp/converted_dreamx_world_ar` or `/root/data/dreamx_world_ar_converted`, `TORCH_SDPA`, 192x192, 81 frames, 4 steps, seed 2048, and min SSIM 0.98; local A40 and Modal L40S references were seeded under `fastvideo/tests/ssim/reference_videos/default/{A40,L40S}_reference_videos/DreamX-World-5B/TORCH_SDPA/`, and both tests passed non-skip on 2026-07-02 after fresh generated-output cleanup was added to the SSIM helper. Modal L40S validation checked out `post-fix dreamx-world-5b-cam branch commit`, seeded the missing AR L40S reference, reran the test, and wrote `mean_ssim=1.0`. A cross-device A40-vs-L40S reference spot check produced mean SSIM 0.7770, so CI should use the L40S-specific reference rather than the A40 artifact. Full-quality params are present for 5B-Cam 480x832/161 frames/30 steps and AR 704x1280/1005 frames/4 steps; publishing references to the HF dataset remains a release operation requiring a write-capable HF token env var, never a raw token value. diff --git a/tests/local_tests/dreamx_world/__init__.py b/tests/local_tests/dreamx_world/__init__.py deleted file mode 100644 index 988131360..000000000 --- a/tests/local_tests/dreamx_world/__init__.py +++ /dev/null @@ -1 +0,0 @@ -# SPDX-License-Identifier: Apache-2.0 diff --git a/tests/local_tests/dreamx_world/test_dreamx_world_ar_conversion.py b/tests/local_tests/dreamx_world/test_dreamx_world_ar_conversion.py deleted file mode 100644 index f80c41917..000000000 --- a/tests/local_tests/dreamx_world/test_dreamx_world_ar_conversion.py +++ /dev/null @@ -1,58 +0,0 @@ -# SPDX-License-Identifier: Apache-2.0 -"""DreamX-World-5B autoregressive conversion smoke tests.""" - -import json - -from fastvideo.configs.pipelines.dreamx_world import make_dreamx_world_5b_ar_dit_config -from fastvideo.models.registry import _LEGACY_FAST_VIDEO_MODELS -from scripts.checkpoint_conversion.dreamx_world_ar_to_diffusers import ( - MODEL_INDEX, - REUSED_COMPONENTS, - TRANSFORMER_CONFIG, - convert_transformer, - write_model_index, -) - - -def test_dreamx_world_ar_converter_writes_symlinked_transformer_and_model_index(tmp_path): - source = tmp_path / "raw" - source.mkdir() - raw_tensor = source / "model.safetensors" - raw_tensor.write_bytes(b"placeholder") - component_source = tmp_path / "wan22" - output = tmp_path / "dreamx_ar" - - for component in REUSED_COMPONENTS: - component_dir = component_source / component - component_dir.mkdir(parents=True) - (component_dir / "config.json").write_text("{}\n") - - convert_transformer(source, output, symlink_transformer=True) - write_model_index(output, component_source, symlink_components=True) - - assert (output / "transformer" / "model.safetensors").is_symlink() - model_index = json.loads((output / "model_index.json").read_text()) - assert model_index == MODEL_INDEX - assert model_index["_class_name"] == "DreamXWorldARPipeline" - assert model_index["transformer"] == ["diffusers", "DreamXWorldARTransformer3DModel"] - - -def test_dreamx_world_ar_transformer_config_matches_pipeline_dit_config(): - dit_config = make_dreamx_world_5b_ar_dit_config() - assert TRANSFORMER_CONFIG["_class_name"] == "DreamXWorldARTransformer3DModel" - assert TRANSFORMER_CONFIG["num_attention_heads"] == dit_config.num_attention_heads - assert TRANSFORMER_CONFIG["attention_head_dim"] == dit_config.attention_head_dim - assert TRANSFORMER_CONFIG["in_channels"] == dit_config.in_channels - assert TRANSFORMER_CONFIG["out_channels"] == dit_config.out_channels - assert TRANSFORMER_CONFIG["ffn_dim"] == dit_config.ffn_dim - assert TRANSFORMER_CONFIG["num_layers"] == dit_config.num_layers - assert TRANSFORMER_CONFIG["local_attn_size"] == dit_config.local_attn_size - assert TRANSFORMER_CONFIG["sink_size"] == dit_config.sink_size - assert TRANSFORMER_CONFIG["attn_compress"] == dit_config.attn_compress - assert tuple(TRANSFORMER_CONFIG["cam_self_attn_layers"]) == dit_config.cam_self_attn_layers - - -def test_dreamx_world_ar_model_index_component_classes_are_registered(): - for component in ("scheduler", "text_encoder", "transformer", "vae"): - class_name = MODEL_INDEX[component][1] - assert class_name in _LEGACY_FAST_VIDEO_MODELS diff --git a/tests/local_tests/dreamx_world/test_dreamx_world_ar_transformer_parity.py b/tests/local_tests/dreamx_world/test_dreamx_world_ar_transformer_parity.py deleted file mode 100644 index 6d0f59518..000000000 --- a/tests/local_tests/dreamx_world/test_dreamx_world_ar_transformer_parity.py +++ /dev/null @@ -1,189 +0,0 @@ -# SPDX-License-Identifier: Apache-2.0 -"""DreamX-World-5B autoregressive transformer parity. - -Coverage scope: both.

The full pinned suite passed 34/34; production equality, bf16 thresholds, strict loading, and official Tongyi oracle are unchanged. | -| 2026-07-14 | Carry the native FastVideo pipeline, example/parity, SSIM test, and L40S seed workflow on PR #1339. | The author explicitly requested the pipeline and quality regression on the same PR rather than a follow-up. | Implementation, component closure, native GPU parity, and reference publication are complete. Later commits do not change inference math. | -| 2026-07-14 | Treat the exact production `AutoModel` loader as the required pipeline text encoder and direct native-Qwen parity as a separate quality row. | `TextEncoderLoader` calls `Qwen3ForCausalLM.from_pretrained_local`, which returns body-only Transformers `AutoModel`; the pipeline does not direct-construct FastVideo-native Qwen. | The production component is exact.
