Adlik [ædlik] is an end-to-end optimizing framework for deep learning models. The goal of Adlik is to accelerate deep learning inference process both on cloud and embedded environment.

With Adlik framework, different deep learning models can be deployed to different platforms with high performance in a much flexible and easy way.

1. In cloud environment, the compiled model and Adlik Inference Engine should be built as a docker image, and deployed as a container.

2. In edge environment, Adlik Inference Engine should be deployed as a container. The compiled model should be transferred to edge environment, and the Adlik Inference Engine should automatically update and load model.

3. In device environment, Adlik Inference Engine and the compiled model should be compiled into a binary file (so or lib). Users who want to run model inference on device should link user defined AI function and Adlik binary file to the execution file, and run directly.

We test the inference performance of Adlik on the same CPU or GPU using the simple CNN model (MNIST model), the ResNet50 model, and InceptionV3 with different serving engines. The test performance data of Adlik on different models are as follows:

• The test result of the MNIST model
• The test result of the ResNet50 model
• The test result of the InceptionV3 model
• The test result of the YoloV3 model
• The test result of the Bert model
• The test result of PaddlePaddle model

Model optimizer focuses on specific hardware and runs on it to achieve acceleration. The proposed framework mainly consists of two categories of algorithm components, i.e. pruner and quantizer.

Model compiler supports several optimizing technologies like pruning, quantization and structural compression, which can be easily used for models developed with TensorFlow, Keras, PyTorch, etc.

Serving Engine provides deep learning models with optimized runtime based on the deployment environment. Put simply, based on a deep learning model, the users of Adlik can optimize it with model compiler and then deploy it to a certain platform with Adlik serving platform.

All Adlik compiler images and serving images are stored in Alibaba Cloud. These images can be downloaded and used directly, users do not need to build the Adlik on Ubuntu. Users can use the compiler images to compile model from H5, CheckPoint, FrozenGraph, ONNX and SavedModel to Openvino, TensorFlow, TensorFlow Lite, TensorRT. Users also can use the serving images for model inference.

Docker pull command:

docker pull docker_image_name:tag

The compiler docker images can be used in CPU and GPU. In the CPU, you can compile the model from source type to TensorFlow model, OpenVino model and TensorFlow Lite model. And in the CPU, you can compile the model from source type to TensorFlow model, and TensorRT model. The name and label of compiler mirror are shown below, and the first half of label represents the version of TensorRT, the latter part of label represents the version of CUDA:

registry.cn-beijing.aliyuncs.com/adlik/model-compiler:v1.0

1. Run the image.

   docker run -it --rm -v source_model:/mnt/model
   registry.cn-beijing.aliyuncs.com/adlik/model-compiler:v1.0 bash

2. Configure the json file or environment variables required to compile the model.

   The config_schema.json describle the json file field information, and for the example, you can reference compiler_json_example.json. For the environment variable field description, see env_field.txt, for the example, reference compiler_env_example.txt.

   Note: The checkpoint model must be given the input and output op names of the model when compiling, and other models can be compiled without the input and output op names of the model.

3. Compile the model.

   Compilation instructions (json file mode):

   python3 "-c" "import json; import model_compiler as compiler; file=open('/mnt/model/serving_model.json','r');
   request = json.load(file);compiler.compile_model(request); file.close()"

   Compilation instructions (environment variable mode):

   python3 "-c" "import model_compiler.compiler as compiler;compiler.compile_from_env()"

The serving docker images contains CPU and GPU mirrors. The label of openvino image represents the version of OpenVINO. And for the TensorRT image the first half of label represents the version of TensorRT, the latter part of label represents the version of CUDA. The names and labels of serving mirrors are as follows:

CPU:

registry.cn-beijing.aliyuncs.com/adlik/serving-tflite-cpu:v1.0

registry.cn-beijing.aliyuncs.com/adlik/serving-tensorflow-cpu:v1.0

registry.cn-beijing.aliyuncs.com/adlik/serving-openvino:v1.0

registry.cn-beijing.aliyuncs.com/adlik/serving-libtorch-cpu:v1.0

GPU:

registry.cn-beijing.aliyuncs.com/adlik/serving-tftrt-gpu:v1.0

registry.cn-beijing.aliyuncs.com/adlik/serving-tensorrt:v1.0

registry.cn-beijing.aliyuncs.com/adlik/serving-libtorch-gpu:v1.0

1. Run the mirror and pay attention to mapping out the service port.

   docker run -it --rm -p 8500:8500 -v compiled_model:/model
   registry.cn-beijing.aliyuncs.com/adlik/serving-openvino:v1.0 bash

2. Load the compiled model in the image and start the service.

   adlik-serving --grpc_port=8500 --http_port=8501 --model_base_path=/model

3. Install the client wheel package adlik serving package or adlik serving gpu package locally, execute the inference code, and perform inference.

Note: If the service port is not mapped when you run the mirror, you need install the adlik serving package or adlik serving gpu package in the container. Then execute the inference code, and perform inference in the container.
