RedisAI

A Redis module for serving tensors and executing deep learning models.

Cloning

If you want to run examples, make sure you have git-lfs installed when you clone.

Quickstart

1. Docker
2. Build

Docker

To quickly tryout RedisAI, launch an instance using docker:

docker run -p 6379:6379 -it --rm redislabs/redisai:edge-cpu

For docker instance with GPU support, you can launch it from tensorwerk/redisai-gpu

docker run -p 6379:6379 --gpus all -it --rm redislabs/redisai:edge-gpu

But if you'd like to build the docker image, you need a machine that has Nvidia driver (CUDA 10.0), nvidia-container-toolkit and Docker 19.03+ installed. For detailed information, checkout nvidia-docker documentation

docker build -f Dockerfile-gpu -t redisai-gpu .
docker run -p 6379:6379 --gpus all -it --rm redisai-gpu

Note that Redis config is located at /usr/local/etc/redis/redis.conf which can be overridden with a volume mount

Give it a try

On the client, set the model

redis-cli -x AI.MODELSTORE foo TF CPU INPUTS 2 a b OUTPUTS 1 c BLOB < tests/test_data/graph.pb

Then create the input tensors, run the computation graph and get the output tensor (see load_model.sh). Note the signatures:

• AI.TENSORSET tensor_key data_type dim1..dimN [BLOB data | VALUES val1..valN]
• AI.MODELRUN graph_key INPUTS input_key1 ... OUTPUTS output_key1 ...

redis-cli
> AI.TENSORSET bar FLOAT 2 VALUES 2 3
> AI.TENSORSET baz FLOAT 2 VALUES 2 3
> AI.MODELRUN foo INPUTS bar baz OUTPUTS jez
> AI.TENSORGET jez META VALUES
1) dtype
2) FLOAT
3) shape
4) 1) (integer) 2
5) values
6) 1) "4"
   2) "9"

Building

You should obtain the module's source code and submodule using git like so:

git clone --recursive https://github.com/RedisAI/RedisAI

This will checkout and build and download the libraries for the backends (TensorFlow, PyTorch, ONNXRuntime) for your platform. Note that this requires CUDA 10.0 to be installed.

bash get_deps.sh

Alternatively, run the following to only fetch the CPU-only backends even on GPU machines.

bash get_deps.sh cpu

Once the dependencies are downloaded, build the module itself. Note that CMake 3.0 or higher is required.

ALL=1 make -C opt clean build

Note: in order to use the PyTorch backend on Linux, at least gcc 4.9.2 is required.

Running the server

You will need a redis-server version 5.0.7 or greater. This should be available in most recent distributions:

redis-server --version
Redis server v=5.0.7 sha=00000000:0 malloc=libc bits=64 build=c49f4faf7c3c647a

To start Redis with the RedisAI module loaded:

redis-server --loadmodule install-cpu/redisai.so

Client libraries

Some languages have client libraries that provide support for RedisAI's commands:

Project	Language	License	Author	URL
JRedisAI	Java	BSD-3	RedisLabs	Github
redisai-py	Python	BSD-3	RedisLabs	Github
redisai-go	Go	BSD-3	RedisLabs	Github
redisai-js	Typescript/Javascript	BSD-3	RedisLabs	Github
redis-modules-sdk	TypeScript	BSD-3-Clause	Dani Tseitlin	Github
redis-modules-java	Java	Apache-2.0	dengliming	Github

Backend Dependancy

RedisAI currently supports PyTorch (libtorch), Tensorflow (libtensorflow), TensorFlow Lite, and ONNXRuntime as backends. This section shows the version map between RedisAI and supported backends. This extremely important since the serialization mechanism of one version might not match with another. For making sure your model will work with a given RedisAI version, check with the backend documentation about incompatible features between the version of your backend and the version RedisAI is built with.

RedisAI	PyTorch	TensorFlow	TFLite	ONNXRuntime
0.1.0	1.0.1	1.12.0	None	None
0.2.1	1.0.1	1.12.0	None	None
0.3.1	1.1.0	1.12.0	None	0.4.0
0.4.0	1.2.0	1.14.0	None	0.5.0
0.9.0	1.3.1	1.14.0	2.0.0	1.0.0
1.0.0	1.5.0	1.15.0	2.0.0	1.2.0
master	1.7.0	1.15.0	2.0.0	1.2.0

Note: Keras and TensorFlow 2.x are supported through graph freezing. See this script to see how to export a frozen graph from Keras and TensorFlow 2.x. Note that a frozen graph will be executed using the TensorFlow 1.15 backend. Should any 2.0 ops be not supported on the 1.15 after freezing, please open an Issue.
