ModelHandler

ModelHandler exposes machine learning models as APIs that applications can use via Python or over a REST API.

To do so, add a modelhandler endpoint

url:
  modelhandler:
    pattern: /$YAMLURL/model/(.*?)/(.*?)
    handler: ModelHandler
    kwargs:
      path: $YAMLPATH # The local directory to store model files/training data etc.

You could submit URL query parameters like FormHandler `/model//?col1=val1&col2=val2&col1=val3.. to train a dataset, classify a record, inserts data, delete model etc.

This will help you create quick forms like below

See the documentation.

Admin

Admin info

The info page shows information about versions, paths and other details about Gramex and its dependencies.

To enable it, ensure that you specify:

• Either components: [..., info, ...], i.e. include info in components:
• Or do not specify any components:

This exposes JSON data at <admin-page>/info as a list of objects consistent with FormHandler.

[
    {"section":"git","key":"path","value":"D:\\bin\\git.EXE","error":null},
    {"section":"git","key":"version","value":"git version 2.15.1\n","error":""},{"section":"gramex","key":"memory usage","value":153411584,"error":""},
    ...
]

See the documentation.

See the Admin info.

Admin console (webshell)

Webshell now makes handler object avaiable to the user. This will make handler related debugging easier.

Upgrade

Note: gramex >= 1.41 onwards requires Anaconda >= 5.2.0

To upgrade Gramex, run:

pip install --verbose gramex==1.46

To upgrade apps dependencies, run:

gramex setup --all

This downloads Chromium and other front-end dependencies. That may take time.
