source .env/bin/activate

# In PowerShell
py -3.6 -m venv .env
.env\scripts\activate

Install dependencies

The names and versions of the required packages are already listed in the requirements.txt file. Use the following command to install these dependencies using pip:

pip install -r requirements.txt

Test

Use the following command to run the Functions host locally.

func host start

Trigger the function from the command line using curl in a new terminal window:

curl -w '\n' http://localhost:7071/api/classify?img=<image_url>

Publish to Azure

Using the Azure Functions Core Tools, run the following command. Replace <APP_NAME> with the name of your Linux Function App.

func azure functionapp publish <APP_NAME> --build-native-deps
