Deep API

Deep Learning as Cloud APIs.

This project provides pre-trained deep learning models as a cloud API service. A web interface is available as well.

Quick Start
API Client
- Using curl
- Using Python
Concurrent clients
Full APIs

Quick Start

Python 3:

$ pip3 install -r requirements.txt
$ python main.py

Anaconda:

$ conda env create -f environment.yml
$ conda activate cloudapi
$ python main.py

Using Docker:

docker run -p 8080:8080 wuhanstudio/deep-api

Navigate to https://localhost:8080

API Client

It's possible to get predictions by sending a POST request to http://127.0.0.1:8080/vgg16_cifar10.

Using curl:

```
export IMAGE_FILE=test/cat.jpg
(echo -n '{"file": "'; base64 $IMAGE_FILE; echo '"}') | \
curl -H "Content-Type: application/json" \
     -d @- http://127.0.0.1:8080/vgg16_cifar10
```

Using Python:

def classification(url, file):
    # Load the input image and construct the payload for the request
    image = Image.open(file)
    buff = BytesIO()
    image.save(buff, format="JPEG")

    data = {'file': base64.b64encode(buff.getvalue()).decode("utf-8")}
    return requests.post(url, json=data).json()

res = classification('http://127.0.0.1:8080/vgg', 'cat.jpg')

This python script is available in the test folder. You should see prediction results by running python3 minimal.py:

cat            0.99804
deer           0.00156
truck          0.00012
airplane       0.00010
dog            0.00009
bird           0.00005
ship           0.00003
frog           0.00001
horse          0.00001
automobile     0.00001

Concurrent clients

Sending 5 concurrent requests to the api server:

$ python3 multi-client.py --num_workers 5 cat.jpg

You should see the result:

Post URLs:

Model	Dataset	Post URL
VGG-16	Cifar10	http://127.0.0.1:8080/vgg16_cifar10
VGG-16	ImageNet	http://127.0.0.1:8080/vgg16
Resnet-50	ImageNet	http://127.0.0.1:8080/resnet50
Inception v3	ImageNet	http://127.0.0.1:8080/inceptionv3

Post Data (JSON):

{
  "file": ""
}

Query Parameters:

Name	Type	Default	Value
top	integer	10	One of [1, 3, 5, 10], top=5 returns top 5 predictions.
no-prob	integer	0	no-prob=1 returns labels without probabilities. no-prob=0 returns labels and probabilities.

Example post urls (returns top 10 predictions with probabilities):

http://127.0.0.1:8080/vgg16?top=10&no-prob=0

Returns (JSON):

Key	Value
success	True / False
Predictions	Array of prediction results, each element contains {"labels": "cat", "probability": 0.99}
error	The error message if any

Example returned json:
