Loud ML Python API Clientedit

The loudml-python [package](https://pypi.org/project/loudml-python/) available on PyPI is a command line client designed to control the Loud ML model server.

If you’ve installed loudml-python locally, the loudml command should be available via the command line. Executing loudml will start the CLI and automatically connect to the local Loud ML model server instance (assuming you have already started the server with systemctl start loudmld or by running loudmld directly). The output should look like this:

$ loudml
Connected to localhost:8077 version 1.6.0-577c87de
Loud ML shell 1.6.0-42136d38


$ loudml -h

usage: loudml [-h] [-A ADDR] [-q] [--version] [-e EXECUTE]

    # Use loudml in a non-interactive mode to output the two days forecast
    # for model "test-model" and pretty print the output:
    $ loudml --execute 'forecast-model -f now -t now+2d test-model'

    # Connect to a specific Loud ML model server:
    $ loudml --addr hostname:8077
