dojo-cli 0.1.7

A command-line interface for black box model execution.

dojo-cli

A command-line interface library for black box domain model execution. This library enables users to execute domain models locally.

The library has 7 key methods:

• List the latest versions of all available models.
• Print parameter metadata for a selected model.
• Print a summary of the output and accessory files of a selected model.
• Print a desription of a selected model.
• Get the results of a detached model run that has finished.
• Run a model.
• List all versions of a model.

Installation

Ensure you have a working installation of Docker.

Once Docker is installed on Linux or Mac you can add the current user to the Docker group with:

sudo groupadd docker
sudo gpasswd -a $USER docker

then log out/back in so changes can take effect. This should be done after installing Docker.

Dojo-cli can be installed via pip:

pip install dojo-cli

Demo script

A text file demonstrating the commands for dojo-cli installation and use is located at /docs/demo_script.txt.

Running models attached vs. detached

By default the runmodel command runs the model attached, which means dojo waits for processing to finish before returning control to the command line. For models that take a long time to process, the --attached=False parameter can be used with runmodel to run the model in background, and results used to check for model run completion.

Setup

The CLI requires a configuration file with DOJO API credentials. This filename can be passed with each CLI command via the --config option, or the default file .config will be used.

See example.config for guidance:

{
    "DOJO_URL": "https://dojo-test.com",
    "DOJO_USER": "",
    "DOJO_PWD": ""
}

If running the library locally from source, the following libraries are required to be installed:

Click>=7.0,<8
docker>=5.0.3
Jinja2>=2.11.3

Template CHIRPS-Monthly parameters file written to params_template.json.

Additionally, parameters will write params_template.json with example model parameters:

{
    "month": 1,
    "year": 2021,
    "bounding_box": "[[33.512234, 2.719907], [49.98171,16.501768]]"
}

results

Description

This command is used for models that have been run detached e.g. dojo runmodel -model="mymodel" --attached=False. Normally, models that take a long time to run are executed detached.

The results command will check whether the model run has completed, and if so, copy the output and logs to the local output folder.

Parameters

• --id : id of the docker container
• --name : name of the docker container
• --config : name of configuation file; defaults to .config

One of either --id or --name is required. When you run a model, the name of the model Docker container will be displayed e.g.

Running Stochastic Gridded Conflict Model version 33cf1a60-2544-420f-ae08-b453a9751cfc in Docker container dojo-stochasticgriddedconflictmodel20211227133418

The model run Docker container id and name will also be listed in the file run-info.txt in the local output folder (see the runmodel section below for information regarding the output directory structure).

The model run Docker container id and name can also be found by the command docker ps -a. Docker containers created by dojo --runmodel will have the dojo- prefix, followed by the model name and a datetime stamp.

Examples

dojo results --name=dojo-mymodel20211225133418

If the model is still running in the container, the above command will produce the following output:

Results for mymodel20211225133418 are not yet ready.

when the model is finished, the output will be:

Run completed.
Model output, run-parameters, and log files are located in "/mydojodata/runs/Stochastic Gridded Conflict Model/33cf1a60-2544-420f-ae08-b453a9751cfc/20211227140758".

runmodel

Description

Runs the selected model used the specified model parameters.

Parameters

• --model : name of the model
• --config : name of configuation file; defaults to .config
• --params : model parameters in JSON format
• --paramsfile : name of file of model parameters in JSON format; defaults to params_template.json.
• --outputdir : folder specified for model output files; defaults to /runs/{model}/{version}/{datetime} e.g. /dojo-cli/runs/CHIRTSmax-Monthly/17bf37e3-3785-43be-a2a3-fec6add03376/20210403110420
• --version : version of the model if --model is not passed
• --attached : True or False, defaults to True.
  • If attached=True or is not passed, the cli will wait for the model to run in the container and then remove the container.
  • If attached=False the model will run in the container in background. The user will use dojo --results to monitor when the model run is finished.

To run a model, the parameter values should either be assigned via the --params option , or a json file specified via the --paramsfile option. If neither parameter option is set, the --paramsfile filename params_template.json will be used.

After processing runmodel will print the local directory where the model output and accessory (e.g. .mp4, .webm, .jpg) files are available. The local directory tree structure will consist of the model name, the model version, and a datetime stamp of the model run (unless specified by the --outputdir option) e.g.:

/runs
 | - Stochastic Gridded Conflict Model
    |-17bf37e3-3785-43be-a2a3-fec6add03376
        |- 20211209160543
        |- output
            |- conflict_IDs.rti
            |- ...
        |- acessorries
            |- conflict_IDs_2D.mp4
            - ...
        |- accessories-captions.json
        |- logs.txt
        |- run-info.txt (only when running --attached=False)
        |- run-parameters.json

In addition to the model's output and accessory files, runmodel will write three other files:

• accessories-captions.json : descriptions of the files in accessories
• logs.txt : the log output produced by this run
• run-info.txt : model run information used by dojo. Includes docker container name and id.
• run-parameters.json : the model parameters used for this run

Examples

(1) Run the CHIRPS-Monthly model using the default configuration settings in .config and model parameters in params_template.json:

dojo runmodel --model="CHIRPS-Monthly"

(2) Run the CHIRPS-Monthly model using the default configuration settings in .config and model parameters in chirps-monthly.json:

dojo runmodel --model="CHIRPS-Monthly" --paramsfile=chirps-monthly.json

(3) Run the CHIRPS-Monthly model using the default configuration settings in .config and specified model parameters:

dojo runmodel --model="CHIRPS-Monthly" --params='{"month": "09", "year": "2016", "bounding_box": "[[33.512234, 2.719907], [49.98171,16.501768]]"}'

(4) Run a specific version of CHIRPS-Monthly:

dojo runmodel --version="a14ccbdf-c8d5-4816-af52-8b2ef3da9d22"

(5) Run a specific version of CHIRPS-Monthly detached:

dojo runmodel --version="a14ccbdf-c8d5-4816-af52-8b2ef3da9d22" --attached=False

Models missing Docker images

In some instances a user may attempt to run a model version that does not have a docker image associated with it. If this occurs dojo-cli will list available model versions (most recent first). The user can then choose to run one of versions listed.

$ dojo runmodel --version="9d077a11-9db3-441c-a2ae-0ecacd1381f0"
APSIM-Cropping version 9d077a11-9db3-441c-a2ae-0ecacd1381f0 does not have a Docker image associated with it and therefore cannot be run.

The following versions of APSIM-Cropping are available to run:
