Batch API

Each indicoio function can process many examples with a single request. Simply pass in a list of inputs and receive a list of results in return.

>>> from indicoio import sentiment

>>> sentiment(['Best day ever', 'Worst day ever'])
[0.9899001220871786, 0.005709885173415242]

Calling multiple APIs with a single function

There are two multiple API functions predict_text and predict_image. These functions are similar to the existing api functions, but take in an additional apis argument as a list of strings of API names (defaults to all existing apis). predict_text accepts a list of existing text APIs and vice versa for predict_image. These functions also support batch as the other functions do.

Accepted text API names: text_tags, political, sentiment, language

Accepted image API names: fer, facial_features, image_features

>>> from indicoio import predict_text, predict_image, predict_text, predict_image

>>> predict_text('Best day ever', apis=["sentiment", "language"])
{'sentiment': 0.9899001220871786, 'language': {u'Swedish': 0.0022464881013042294, u'Vietnamese': 9.887170914498351e-05, ...}}
