Release 2.10.0 corresponding to NGC container 21.05

Triton Inference Server

The Triton Inference Server provides a cloud inferencing solution optimized for both CPUs and GPUs. The server provides an inference service via an HTTP or GRPC endpoint, allowing remote clients to request inferencing for any model being managed by the server. For edge deployments, Triton Server is also available as a shared library with an API that allows the full functionality of the server to be included directly in an application.

What's New In 2.10.0

Triton on Jetson now supports ONNX via the ONNX Runtime backend.
The Triton server and HTTP clients (Python and C++) now support compression.
Ragged batching is now supported for ONNX models.
The Triton clients have moved to a separate repo: https://github.com/triton-inference-server/client
Trace now correctly reports all timestamps for all backends.
NVTX annotations are fixed.
The legacy custom backend support is removed. All custom backends must be implemented using the TRITONBACKEND API described here: https://github.com/triton-inference-server/backend
Added CLI subcommands in Model Analyzer for profile, analyze, and report. See CLI documentation for usage instructions.
- This is a breaking change and requires updating Model Analyzer config files and CLI flags. See Configuring Model Analyzer and Quick Start for more information.
Model Analyzer can create a detailed report of any specific model configuration with the report subcommand.
CPU only mode is now supported in Model Analyzer.

Known Issues

There are backwards incompatible changes in the example Python client shared-memory support library when that library is used for tensors of type BYTES. The utils.serialize_byte_tensor() and utils.deserialize_byte_tensor() functions now return np.object_ numpy arrays where previously they returned np.bytes_ numpy arrays. Code depending on np.bytes_ must be updated. This change was necessary because the np.bytes_ type removes all trailing zeros from each array element and so binary sequences ending in zero(s) could not be represented with the old behavior. Correct usage of the Python client shared-memory support library is shown in https://github.com/triton-inference-server/server/blob/r21.03/src/clients/python/examples/simple_http_shm_string_client.py.
Some versions of Google Kubernetes Engine (GKE) contain a regression in the handling of LD_LIBRARY_PATH that prevents the inference server container from running correctly (see issue 141255952). Use a GKE 1.13 or earlier version or a GKE 1.14.6 or later version to avoid this issue.

Client Libraries and Examples

v2.9.0

b4d6cc2

Release 2.9.0 corresponding to NGC container 21.04

Triton Inference Server

What's New In 2.9.0

Python backend performance has been increased significantly.
Onnx Runtime update to version 1.7.1.
Triton Server is now available as a GKE Marketplace Application, see https://github.com/triton-inference-server/server/tree/master/deploy/gke-marketplace-app.
The GRPC client libraries now allow compression to be enabled.
Ragged batching is now supported for TensorFlow models.
For TensorFlow models represented with SavedModel format, it is now possible to choose which graph and signature_def to load. See https://github.com/triton-inference-server/tensorflow_backend/tree/r21.04#parameters.
A Helm Chart example is added for AWS. See https://github.com/triton-inference-server/server/tree/master/deploy/aws.
The Model Control API is enhanced to provide an option when unloading an ensemble model. The option allows all contained models to be unloaded as part of unloading the ensemble. See https://github.com/triton-inference-server/server/blob/master/docs/protocol/extension_model_repository.md#model-repository-extension.
Model reloading using the Model Control API previously resulted in the model being unavailable for a short period of time. This is now fixed so that the model remains available during reloading.
Latency statistics and metrics for TensorRT models are fixed. Previously the sum of the "compute input", "compute infer" and "compute output" times accurately indicated the entire compute time but the total time could be incorrectly attributed across the three components. This incorrect attribution is now fixed and all values are now accurate.
Error reporting is improved for the Azure, S3 and GCS cloud file system support.
Fix trace support for ensembles. The models contained within an ensemble are now traced correctly.
Model Analyzer improvements
- Summary report now includes GPU Power usage
- Model Analyzer will find the Top N model configuration across multiple models.

Release 2.8.0 corresponding to NGC container 21.03

Triton Inference Server

What's New In 2.8.0

The Windows build now supports ONNX models.
Repository agent is a new extensibility C API added to Triton that allows implementation of custom authentication, decryption, conversion, or similar operations when a model is loaded. See https://github.com/triton-inference-server/server/blob/master/docs/repository_agents.md
An OpenVINO backend is added to Triton to enable the execution of OpenVINO models on CPUs. https://github.com/triton-inference-server/openvino_backend

v2.7.0

c7d7b00

Release 2.7.0 corresponding to NGC container 21.02

Triton Inference Server

What's New In 2.7.0

Fix bug in TensorRT backend that could, in rare cases, lead to corruption of output tensors.
Fix performance issue in the HTTP/REST client that occurred when the client does not explicitly request specific outputs.
In this case all outputs are now returned as binary data where previously they were returned as JSON.
Add an example Java and Scala client based on GRPC-generated API.
Extend perf_analyzer to be able to work with TFServing and TorchServe.
The legacy custom backend API is deprecated and will be removed in a future release. The Triton Backend API should be used as the API for custom backends. The Triton Backend API remains fully supported and that support will continue indefinitely.
Model Analyzer parameters and test model configurations can be specified with YAML configuration file.
Model Analyzer will report performance metrics for end-to-end latency and CPU memory usage.
Refer to the 21.02 column of the Frameworks Support Matrix
for container image versions that the 21.02 inference server container is based on.
Ubuntu 20.04 with January 2021 updates.

Known Issues

TensorRT reformat-free I/O is not supported.
Some versions of Google Kubernetes Engine (GKE) contain a regression in the handling of LD_LIBRARY_PATH that prevents the inference server container from running correctly (see issue 141255952). Use a GKE 1.13 or earlier version or a GKE 1.14.6 or later version to avoid this issue.
Observed memory leak in gRPC client library. Suggested workaround: restart client processes periodically or minimize creation of new InferenceServerGrpcClient objects. For more details on the issue in gRPC, please reference: #2517. The memory leak is fixed on master branch by #2533 and the fix will be included in the 21.03 release. If required, the change can be applied to the 21.02 branch and the client library can be rebuilt: https://github.com/triton-inference-server/server/blob/master/docs/client_libraries.md.

Release 2.6.0 corresponding to NGC container 20.12

Triton Inference Server

What's New In 2.6.0

An alpha release Triton for Windows is included in this release. See below for more details.
Due to interactions with Ubuntu 20.04, the ONNX Runtime's OpenVINO execution provider is disabled in this release. OpenVINO support will be re-enabled in a subsequent release.
The Triton *-py3-clientsdk container has been renamed to *-py3-sdk and now contains the Model Analyzer as well as the client libraries and examples.
The PyTorch backend has been moved to a separate repository: https://github.com/triton-inference-server/pytorch_backend. As a result, it is now easy to add or remove it from Triton without requiring a rebuild: https://github.com/triton-inference-server/server/blob/master/docs/compose.md.

v2.5.0

b431e28

Release 2.5.0 corresponding to NGC container 20.11

NVIDIA Triton Inference Server

The NVIDIA Triton Inference Server provides a cloud inferencing solution optimized for NVIDIA GPUs. The server provides an inference service via an HTTP or GRPC endpoint, allowing remote clients to request inferencing for any model being managed by the server. For edge deployments, Triton Server is also available as a shared library with an API that allows the full functionality of the server to be included directly in an application.

What's New In 2.5.0

ONNX Runtime backend updated to use ONNX Runtime 1.5.3.
The PyTorch backend is moved to a dedicated repo triton-inference-server/pytorch_backend.
The Caffe2 backend is removed. Caffe2 models are no longer supported.
Fix handling of failed model reloads. If a model reload fails, the currently loaded version of the model will remain loaded and its availability will be uninterrupted.
Releasing Triton ModelAnalyzer in the Triton SDK container and as a PIP package available in NVIDIA PyIndex.
Refer to the 20.11 column of the Frameworks Support Matrix
for container image versions that the 20.11 inference server container is based on.
Ubuntu 18.04 with September 2020 updates.

Known Issues

TensorRT reformat-free I/O is not supported.
Some versions of Google Kubernetes Engine (GKE) contain a regression in the handling of LD_LIBRARY_PATH that prevents the inference server container from running correctly (see issue 141255952). Use a GKE 1.13 or earlier version or a GKE 1.14.6 or later version to avoid this issue.

Client Libraries and Examples

Ubuntu 18.04 builds of the client libraries and examples are included in this release in the attached v2.5.0_ubuntu1804.clients.tar.gz file. See Getting the Client Libraries for more information on the client libraries and examples. The client SDK is also available as a NGC Container.

v2.3.0

3159e73

Release 2.3.0 corresponding to NGC container 20.09

NVIDIA Triton Inference Server

What's New In 2.3.0

Python Client library is now a pip package available from the NVIDIA pypi index. See Python client documentation for more information.
The custom backend API, custom.h and associated custom backend SDK are no longer provided as part of the Triton release. Existing custom backends will continue to work with Triton and older releases of the SDK can still be used to create "legacy" custom backends. However, all users are strongly encouraged to move to the new Triton backend API.
Fix a performance issue with the HTTP/REST protocol and the Python client library that caused reduced performance when outputs were not requested explicitly in an inference request.
Fix some bugs in reporting of statistics for ensemble models.
GRPC updated to version 1.25.0.

Known Issues

The KFServing HTTP/REST and GRPC protocols and corresponding V2 experimental Python and C++ clients are beta quality and are likely to change. Specifically:
- The data returned by the statistics API will be changing to include additional information.
- The data returned by the repository index API will be changing to include additional information.
The new C API specified in tritonserver.h is beta quality and is likely to change.
