v15.5: latest TensorRT library, CoreML backend

TRT

• Upgraded to TensorRT 10.5.0.
• Volta GPUs (TITAN V, V100) are no longer supported.

ORT

• Fix MacOS CoreML support for vsort by @yuygfgg in #106.

  This pull request also added theORT_COREML backend to vsmlrt.py.

General

• Upgraded to CUDA 12.6.1.

vsmlrt.py

• Added support for RIFE v4.25 and v4.26 models.

• Added automatic batch inference support via batch_size option in inference() and flexible_inference(), which may improve device utilization for inference on small inputs using some small models.

  • On the one hand, batching improves utilization by creating more work for each kernel invocation and reducing quantization inefficiency of kernel tiles in bulk parallelism. It also reduces average kernel launch and synchronization overhead per work.
  • On the other hand, however, batching causes cache misses and inserts bubbles in the pipeline that may degrade performance.

  This feature requires flexible output support starting with vs-mlrt v15 and is inspired by styler00dollar/VSGAN-tensorrt-docker@ac47012.

  Note that not all onnx models are supported.

  • Future RIFE v2 models will be fixed to support batch inference.

v15.1: latest TensorRT library

TRT

• Upgraded to TensorRT 10.2.0.

• Add TensorRT release package (vsmlrt-windows-x64-tensorrt). #102

  This package is a strict subset of the CUDA release package, with cuDNN, cuBLAS libraries and support for ORT_CUDA backend removed.

  It supports TRT, OV_*, ORT_CPU, ORT_DML and NCNN_VK backends.

known issue

• Accoding to the documentation,

  There is an up to 4x performance regression for networks containing "GridSample" ops compared to TensorRT 9.2.

  This affects RIFE and SAFA models.

  vs-mlrt v14.test3 is the latest one that is not affected. This will be fixed in the next release by TensorRT 10.3.0.

General

• Upgraded to CUDA 12.5.0.

vsmlrt.py

• Added support for RIFE v4.17 lite and v4.18 models.

Full Changelog: v15...v15.1

v15: latest TensorRT library

General

plugins

• Added parameter flexible_output_prop for flexible output:

  Traditionally, all plugins can only support onnx models with one or three output channels, due to vapoursynth's limitation.

  By using the new flexible output feature, plugins can support onnx models with arbitrary number of output planes.

  from typing import TypedDict
  
  class Output(TypedDict):
      clip: vs.VideoNode
      num_planes: int
  
  prop = "planes" # arbitrary non-empty string
  output = core.ov.Model(src, network_path, flexible_output_prop=prop) # type: Output
  
  clip = output["clip"]
  num_planes = output["num_planes"]
  
  output_planes = [
      clip.std.PropToClip(prop=f"{prop}{i}")
      for i in range(num_planes)
  ] # type: list[vs.VideoNode]

  This feature is supported by all plugins starting with vs-mlrt v15.

vsmlrt.py

• Added support for RIFE v4.17 models.

• Added support for ArtCNN models optimised for anime content. The chroma variants are not supported on previous versions of vs-mlrt, because they require the flexible output feature.

• Added function flexible_inference for flexible output:

  The above sample is simplified as

  output_planes = flexible_inference(src, network_path) # type: list[vs.VideoNode]

TRT

• Upgraded to TensorRT 10.1.0.

known issue

• Accoding to the documentation,

  There is an up to 4x performance regression for networks containing "GridSample" ops compared to TensorRT 9.2.

  This affects RIFE and SAFA models.

  vs-mlrt v14.test3 is the latest one that is not affected.

Community contributions

• Fix multiple flexible_output_prop keyword argument error by @LightArrowsEXE in #97
• Fix missing spaces in exceptions by @LightArrowsEXE in #98

v14: latest libraries

Compared to the previous stable (v13.2) release:

General

• External models are no longer packaged.

vsmlrt.py

• Plugin invocation order in the get_plugin_path() function is sorted to reduce memory consumption.
• Added support for RIFE v4.7 ~ v4.16 (lite, ensemble) models.
• Added support for SCUNet models for image denoising.

TRT

plugin and runtime libraries

• Upgraded to TensorRT 10.0.1.
• Maxwell and Pascal GPUs are no longer supported. Other backends still support these GPUs.
• Reduce GPU memory usage for dynamically shaped engines when the actual tile size is smaller than the maximum tile size set during engine building.
• Reduced engine build time.
• Added long path support for engines on Windows.
• cuDNN is no longer a strict runtime dependency.

vsmlrt.py

• The cuDNN tactic is no longer enabled by default.
• TF32 acceleration is disabled by default.
• The maximum workspace is set to None for the total memory size of the GPU.
• Add parameters builder_optimization_level, max_aux_streams, bf16 (#64), custom_env, custom_args, short_path and engine_folder (#90):
  • builder_optimization_level: "adjust how long TensorRT should spend searching for tactics with potentially better performance" link
  • max_aux_streams: Within-inference multi-streaming, "if enabled, TensorRT will run some layers on the auxiliary streams in parallel to the layers running on the main stream, ..., may increase the memory consumption, ..." link
  • bf16: "TensorRT supports the bfloat16 (brain float) floating point format on NVIDIA Ampere and later architectures ... Note that not all layers support bfloat16." link
  • custom_env, custom_args: custom environment variable and arguments for trtexec engine build.
  • short_path: whether to shorten engine name.
    • On Windows, this could be useful in addressing the maximum path length limitation, and is enabled by default.
  • engine_folder: used to specify custom directory for engines.

known issues

• Accoding to the documentation, There is an up to 4x performance regression for networks containing "GridSample" ops compared to TensorRT 9.2.This affects RIFE and SAFA models.

• trtexec may reports errors like:

  • [E] Error[9]: Skipping tactic 0xded5318b4a444b84 due to exception Cask convolution execution
  • [E] Error[2]: [virtualMemoryBuffer.cpp::nvinfer1::StdVirtualMemoryBufferImpl::resizePhysical::140] Error Code 2: OutOfMemory (no further information)

  This issue has been submitted to NVIDIA.

ORT

• Upgraded to ONNX Runtime v1.18.0.

interface

• The ORT_* backends now support fp16 I/O. The semantics of the fp16 flag in these backends is as follows:
  • Enabling fp16 will use a built-in quantization that converts a fp32 onnx to a fp16 onnx. If the input video is of half-precision floating-point format, the generated fp16 onnx will use fp16 input. The output format can be controlled by the output_format option (0 = fp32, 1 = fp16).
  • Disabling fp16 will not use the built-in quantization. However, if the onnx file itself uses fp16 for computation, the actual computation will be done in fp16. In this case, the input video format should match the input format of the onnx, and the output format is inferred from the onnx.

CUDA

• Reduced execution overhead.
• Added support for TF32 acceleration. This is disabled by default.
• Added experimental prefer_nhwc flag to reduce the number of layout transformations when using tensor cores. This is disabled by default.

OV

• Upgraded to OpenVINO 2024.2.0.
• Added experimental OV_NPU backend for Intel NPUs.

MIGX

• Added support for MIGraphX backend for AMD GPUs. Currently this backend is Linux only.

This release uses CUDA 12.4.1, cuDNN 8.9.7, TensorRT 10.0.1, ONNX Runtime v1.18.0, OpenVINO 2024.2.0 and ncnn 20220915 b16f8ca.

Full Changelog: v13.2...v14

v14.test4: latest TensorRT and ONNX Runtime libraries

This is a preview release for TensorRT 10.0.0, following the v14.test, v14.test2 and v14.test3 releases.

• The TRT backend no longer supports Maxwell and Pascal GPUs. Other backends still support these GPUs. Same as those releases, the current release requires driver version >= 525.

• Added support for SwinIR models for image restoration, which are only supported by the TRT backend and the ORT_CPU backend from vs-mlrt v14.test4 or later. SwinIR-M and SwinIR-L models exhibit precision issue with fp16 implementation, this is under investigation.

• Added support for SCUNet models for image denoising, which are only supported by the TRT backend and the ORT_CPU backend from vs-mlrt v14.test4 or later.

• Added engine_folder argument to the TRT backend in vsmlrt.py to specify custom directory for engines.

• Starting with this pre-release, for dynamically shaped engines, the trt runtime allocates gpu memory based on the actual tile size, whereas in previous releases, the runtime would have to allocate gpu memory based on the maximum tile size set at engine compile time. This feature requires TensorRT 10 or later.

• The ORT_* backends now support fp16 I/O. The semantics of the fp16 flag is as follows:

  • Enabling fp16 will use a built-in quantization that converts a fp32 onnx to a fp16 onnx. If the input video is of half-precision floating-point format, the generated fp16 onnx will use fp16 input. The output format can be controlled by the output_format option (0 = fp32, 1 = fp16).
  • Disabling fp16 will not use the built-in quantization. However, if the onnx file itself uses fp16 for computation, the actual computation will be done in fp16. In this case, the input video format should match the input format of the onnx, and the output format is inferred from the onnx.

• Reduce the overhead of the ORT_CUDA backend.

• Added support for TF32 acceleration to the ORT_CUDA backend. Disabled by default.

• Add experimental prefer_nhwc flag to the ORT_CUDA backend to reduce the number of layout transformations when using tensor cores.

• For production use of the TRT backend, continue to use vsmlrt v13.2. For RIFE and SAFA acceleration on the TRT backend, continue to use any old release.

• Also check the release notes of the previous pre-releases.

v14.test3: latest TensorRT, MIGraphX backend

This is a preview release for TensorRT 9.2.0, following the v14.test and v14.test2 releases.

• Same as those releases, it requires Pascal GPUs or later (10 series+) and driver version >= 525. Support for Kepler 2.0 and Maxwell GPUs is dropped.

• TensorRT 9.2.0 is officially documented as for Large Language Models (LLMs) on NVIDIA A100, A10G, L4, L40, L40S, H100 GPUs, and NVIDIA GH200 Grace Hopper™ Superchip only. The Windows build is downloaded from here, and can be used on other GPU models.

• Users should use the same version of TensorRT as provided (9.2.0) because runtime version checking is disabled in this release.

• Added support for AnimeJaNai V3 models, contributed by contributed by @hooke007 in #82.

• Added support for RIFE v4.13 ~ v4.16 (lite, ensemble) models, which are also available for previous vs-mlrt releases (simply download the new model file here and update vsmlrt.py).

  • The v4.13 ~ v4.15 models should have the same execution speed as the v4.10 - v4.12 models.
  • The v4.13 lite model, the v4.15 lite model and the v4.16 lite model should all have the same execution speed as the v4.12 lite model, while the v4.14 lite model may run slower.

• Added support for fractional video frame interpolation in RIFE.

  • Playback in video players should also set video_player=True (#59 (comment)). This change is experimental.

• Fixed an issue that causes the TRT backend crashes during script realoading. (#65). It is also fixed in the latest iteration of the v14.test2 release.

• RIFE v4.7+ models with v2 representation are not working with dynamic shapes (#72). This has been reported to TensorRT developers.

• Initial MIGraphX support (experimental) for AMD GPUs.

  • fp16 I/O contributed by @abihf in #86.
  • Multi-stream execution, device selection, hip graphs and dynamic shapes are not explicitly supported for now.
