# Release Notes for 2.24.0 | ||
|
||
## New Freatures and Improvements | ||
|
||
* [Auto-Complete](https://github.com/triton-inference-server/server/blob/main/docs/model_configuration.md#auto-generated-model-configuration) | ||
is enabled by default. The `--strict-model-config` option has been soft | ||
deprecated, use the new `--disable-auto-complete-config` CLI option instead. | ||
|
||
* New example backend demonstrating | ||
[Business Logic Scripting in C++](https://github.com/triton-inference-server/backend/blob/r22.07/examples/backends/bls/README.md). | ||
|
||
* Users can provide values for | ||
["init_ops"](https://github.com/triton-inference-server/tensorflow_backend/tree/r22.07#parameters) | ||
in Tensorflow TF1.x GraphDef models through json file. | ||
|
||
* New | ||
[asyncio compatible API](https://github.com/triton-inference-server/client#python-asyncio-support-beta) | ||
to the Python GRPC/HTTP APIs. | ||
|
||
* Added thread pool to reduce service downtime for concurrently loading models. | ||
The thread pool size is configurable with the new `--model-load-thread-count` | ||
tritonserver option. You can find more information | ||
[here](https://github.com/triton-inference-server/server/blob/main/docs/model_management.md#concurrently-loading-models). | ||
|
||
* Model Analyzer now doesn't require `config.pbtxt` file for models that can be | ||
auto-completed in Triton. | ||
|
||
* Refer to the 22.07 column of the | ||
[Frameworks Support Matrix](https://docs.nvidia.com/deeplearning/frameworks/support-matrix/index.html) | ||
for container image versions on which the 22.07 inference server container is | ||
based. | ||
|
||
## Known Issues | ||
|
||
* JetPack release will be published later in the month in order to align with | ||
JetPack SDK public availability. | ||
|
||
* Auto-complete could cause an increase in server start time. To avoid a start | ||
time increase, users should provide the full model configuration. | ||
|
||
* When auto-completing some model configs, backends may generate a model config | ||
even though there is not enough metadata (ex. Graphdef models for Tensorflow | ||
Backend). The user will see the model successfully load but fail to inference. | ||
In this case the user should provide the full model configuration for these | ||
models or use the `--disable-auto-complete-config` CLI option to show which | ||
models fail to load. | ||
|
||
* Can't do autocomplete for PyTorch models, not enough metadata. Can only verify | ||
that the number of inputs is correct and the input names match what is | ||
specified in the model configuration. No info about number of outputs and | ||
datatypes. Related pytorch bug: | ||
https://github.com/pytorch/pytorch/issues/38273. | ||
|
||
* Running inference on multiple TensorRT model instances in Triton may fail | ||
with signal(6). The issue is expected to be fixed in a future release. Details | ||
can be found at https://github.com/triton-inference-server/server/issues/4566. | ||
|
||
* Perf Analyzer stability criteria has been changed which may result in | ||
reporting instability for scenarios that were previously considered stable. | ||
This change has been made to improve the accuracy of Perf Analyzer results. | ||
If you observe this message, it can be resolved by increasing the | ||
`--measurement-interval` in the time windows mode or | ||
`--measurement-request-count` in the count windows mode. | ||
|
||
* Unlike previously noted, 22.07 is the last release that defaults to | ||
[TensorFlow version 1](https://github.com/triton-inference-server/tensorflow_backend/tree/r22.06#--backend-configtensorflowversionint). | ||
From 22.08 onwards Triton will change the default TensorFlow | ||
version to 2.X. | ||
|
||
* Triton PIP wheels for ARM SBSA are not available from PyPI and pip will | ||
install an incorrect Jetson version of Triton for Arm SBSA. | ||
|
||
The correct 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 issue 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. | ||
|
||
* Starting from 22.02, the Triton container, which uses the 22.02 or above | ||
PyTorch container, will report an error during model loading in the PyTorch | ||
backend when using scripted models that were exported in the legacy format | ||
(using our 19.09 or previous PyTorch NGC containers corresponding to | ||
PyTorch 1.2.0 or previous releases). | ||
|
||
To load the model successfully in Triton, you need to export the model again | ||
by using a recent version of PyTorch. |
