## Serve a Model in 3 Easy Steps

```bash
# Step 1: Create the example model repository
git clone -b r23.07 https://github.com/triton-inference-server/server.git
cd server/docs/examples
./fetch_models.sh

# Step 2: Launch triton from the NGC Triton container
docker run --gpus=1 --rm --net=host -v ${PWD}/model_repository:/models nvcr.io/nvidia/tritonserver:23.07-py3 tritonserver --model-repository=/models

# Step 3: Sending an Inference Request
# In a separate console, launch the image_client example from the NGC Triton SDK container
docker run -it --rm --net=host nvcr.io/nvidia/tritonserver:23.07-py3-sdk
/workspace/install/bin/image_client -m densenet_onnx -c 3 -s INCEPTION /workspace/images/mug.jpg

# Inference should return the following
Image '/workspace/images/mug.jpg':
15.346230 (504) = COFFEE MUG
13.224326 (968) = CUP
10.422965 (505) = COFFEEPOT
```
Please read the [QuickStart](docs/getting_started/quickstart.md) guide for additional information
regarding this example. The quickstart guide also contains an example of how to launch Triton on [CPU-only systems](docs/getting_started/quickstart.md#run-on-cpu-only-system). New to Triton and wondering where to get started? Watch the [Getting Started video](https://youtu.be/NQDtfSi5QF4).

### Using Triton

#### Preparing Models for Triton Inference Server

The first step in using Triton to serve your models is to place one or
more models into a [model repository](docs/user_guide/model_repository.md). Depending on
the type of the model and on what Triton capabilities you want to enable for
the model, you may need to create a [model
configuration](docs/user_guide/model_configuration.md) for the model.

- [Add custom operations to Triton if needed by your model](docs/user_guide/custom_operations.md)
- Enable model pipelining with [Model Ensemble](docs/user_guide/architecture.md#ensemble-models)
and [Business Logic Scripting (BLS)](https://github.com/triton-inference-server/python_backend#business-logic-scripting)
- Optimize your models setting [scheduling and batching](docs/user_guide/architecture.md#models-and-schedulers)
parameters and [model instances](docs/user_guide/model_configuration.md#instance-groups).
- Use the [Model Analyzer tool](https://github.com/triton-inference-server/model_analyzer)
to help optimize your model configuration with profiling
- Learn how to [explicitly manage what models are available by loading and
unloading models](docs/user_guide/model_management.md)

#### Configure and Use Triton Inference Server

- Read the [Quick Start Guide](docs/getting_started/quickstart.md) to run Triton Inference
Server on both GPU and CPU
- Triton supports multiple execution engines, called
[backends](https://github.com/triton-inference-server/backend#where-can-i-find-all-the-backends-that-are-available-for-triton), including
[TensorRT](https://github.com/triton-inference-server/tensorrt_backend),
[TensorFlow](https://github.com/triton-inference-server/tensorflow_backend),
[PyTorch](https://github.com/triton-inference-server/pytorch_backend),
[ONNX](https://github.com/triton-inference-server/onnxruntime_backend),
[OpenVINO](https://github.com/triton-inference-server/openvino_backend),
[Python](https://github.com/triton-inference-server/python_backend), and more
- Not all the above backends are supported on every platform supported by Triton.
Look at the
[Backend-Platform Support Matrix](https://github.com/triton-inference-server/backend/blob/main/docs/backend_platform_support_matrix.md)
to learn which backends are supported on your target platform.
- Learn how to [optimize performance](docs/user_guide/optimization.md) using the
[Performance Analyzer](https://github.com/triton-inference-server/client/blob/main/src/c++/perf_analyzer/README.md)
and
[Model Analyzer](https://github.com/triton-inference-server/model_analyzer)
- Learn how to [manage loading and unloading models](docs/user_guide/model_management.md) in
Triton
- Send requests directly to Triton with the [HTTP/REST JSON-based
or gRPC protocols](docs/customization_guide/inference_protocols.md#httprest-and-grpc-protocols)

#### Client Support and Examples

A Triton *client* application sends inference and other requests to Triton. The
[Python and C++ client libraries](https://github.com/triton-inference-server/client)
provide APIs to simplify this communication.

- Review client examples for [C++](https://github.com/triton-inference-server/client/blob/main/src/c%2B%2B/examples),
[Python](https://github.com/triton-inference-server/client/blob/main/src/python/examples),
and [Java](https://github.com/triton-inference-server/client/blob/main/src/java/src/main/java/triton/client/examples)
- Configure [HTTP](https://github.com/triton-inference-server/client#http-options)
and [gRPC](https://github.com/triton-inference-server/client#grpc-options)
client options
- Send input data (e.g. a jpeg image) directly to Triton in the [body of an HTTP
request without any additional metadata](https://github.com/triton-inference-server/server/blob/main/docs/protocol/extension_binary_data.md#raw-binary-request)

### Extend Triton

[Triton Inference Server's architecture](docs/user_guide/architecture.md) is specifically
designed for modularity and flexibility

- [Customize Triton Inference Server container](docs/customization_guide/compose.md) for your use case
- [Create custom backends](https://github.com/triton-inference-server/backend)
in either [C/C++](https://github.com/triton-inference-server/backend/blob/main/README.md#triton-backend-api)
or [Python](https://github.com/triton-inference-server/python_backend)
- Create [decouple backends and models](docs/user_guide/decoupled_models.md) that can send
multiple responses for a request or not send any responses for a request
- Use a [Triton repository agent](docs/customization_guide/repository_agents.md) to add functionality
that operates when a model is loaded and unloaded, such as authentication,
decryption, or conversion
- Deploy Triton on [Jetson and JetPack](docs/user_guide/jetson.md)
- [Use Triton on AWS
Inferentia](https://github.com/triton-inference-server/python_backend/tree/main/inferentia)

# Release Notes for 2.36.0

## New Freatures and Improvements

* ["pytorch_backend"](https://github.com/triton-inference-server/pytorch_backend)
supports implicit state management.

* ["python_backend"](https://github.com/triton-inference-server/python_backend)
supports
[direct serving of TensorFlow SavedModel](https://github.com/triton-inference-server/python_backend/blob/r23.07/src/resources/platform_handlers/tensorflow_savedmodel/README.md).

* ["python_backend"](https://github.com/triton-inference-server/python_backend)
supports
[unpacked Conda execution environment](https://github.com/triton-inference-server/python_backend/tree/r23.07#creating-custom-execution-environments).

* ["python_backend"](https://github.com/triton-inference-server/python_backend)
added the
[model loading APIs](https://github.com/triton-inference-server/python_backend/blob/r23.07/README.md#model-loading-api)
for BLS usage.

* Triton OpenTelemetry trace mode supports ensemble model tracing.

* Triton Python client supports
[DLPack tensors in CUDA shared memory utilities](https://github.com/triton-inference-server/client/tree/r23.07#cuda-shared-memory).

* Triton supports the S3 model repository that contains more than 1000 files.

* Added
[Java binding](https://github.com/bytedeco/javacpp-presets/pull/1361)
of the Triton in-process C++ API.

* Refer to the 23.07 column of the
[Frameworks Support Matrix](https://docs.nvidia.com/deeplearning/frameworks/support-matrix/index.html)
for container image versions on which the 23.07 inference server container is based.

## Known Issues

* The
["fastertransformer_backend"](https://github.com/triton-inference-server/fastertransformer_backend)
build only works with Triton 23.04 and older releases.

* Some systems which implement `malloc()` may not release memory back to the
operating system right away causing a false memory leak. This can be mitigate
by using a different malloc implementation. `tcmalloc` and `jemalloc` are
installed in the Triton container and can be
[used by specifying the library in LD_PRELOAD](https://github.com/triton-inference-server/server/blob/r22.12/docs/user_guide/model_management.md).

We recommend experimenting with both `tcmalloc` and `jemalloc` to determine which
one works better for your use case.

* Auto-complete may cause an increase in server start time. To avoid a start
time increase, users can provide the full model configuration and launch the
server with `--disable-auto-complete-config`.

* Auto-complete does not support PyTorch models due to lack of metadata in the
model. It can only verify that the number of inputs and the input names
matches what is specified in the model configuration. There is no model
metadata about the number of outputs and datatypes. Related PyTorch bug:
https://github.com/pytorch/pytorch/issues/38273

* Triton Client PIP wheels for ARM SBSA are not available from PyPI and pip will
install an incorrect Jetson version of Triton Client library for Arm SBSA. The
correct client wheel file can be pulled directly from the Arm SBSA SDK image
and manually installed.

* Traced models in PyTorch seem to create overflows when int8 tensor values are
transformed to int32 on the GPU. Refer to
https://github.com/pytorch/pytorch/issues/66930 for more information.

* Triton cannot retrieve GPU metrics with MIG-enabled GPU devices (A100 and
A30).

* Triton metrics might not work if the host machine is running a separate DCGM
agent on bare-metal or in a container.
