Quick Start (Application Users)¶

As an App User, you can make predictions on models deployed on Rafiki.

Making predictions¶

Your app developer should have created an inference job and shared predictor_host, the host at which you can send queries to and receive predictions over HTTP.

Send a POST /predict to predictor_host with a body of the following format in JSON:

{
    "query": <query>
}

…where the format of <query> depends on the associated task (see Supported Tasks).

The body of the response will be of the following format in JSON:

{
    "prediction": <prediction>
}

…where the format of <prediction> depends on the associated task.

Example:

If predictor_host is 127.0.0.1:30000, run the following in shell:

predictor_host='127.0.0.1:30000'
body='{"query": [[0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0], [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0], [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0], [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0], [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0], [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0], [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0], [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 3, 1, 0, 0, 7, 0, 37, 0, 0], [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 2, 0, 27, 84, 11, 0, 0, 0, 0, 0, 0, 119, 0, 0], [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 88, 143, 110, 0, 0, 0, 0, 22, 93, 106, 0, 0], [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 4, 0, 53, 129, 120, 147, 175, 157, 166, 135, 154, 168, 140, 0, 0], [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 2, 0, 11, 137, 130, 128, 160, 176, 159, 167, 178, 149, 151, 144, 0, 0], [0, 0, 0, 0, 0, 0, 1, 0, 2, 1, 0, 3, 0, 0, 115, 114, 106, 137, 168, 153, 156, 165, 167, 143, 157, 158, 11, 0], [0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 3, 0, 0, 89, 139, 90, 94, 153, 149, 131, 151, 169, 172, 143, 159, 169, 48, 0], [0, 0, 0, 0, 0, 0, 2, 4, 1, 0, 0, 0, 98, 136, 110, 109, 110, 162, 135, 144, 149, 159, 167, 144, 158, 169, 119, 0], [0, 0, 2, 2, 1, 2, 0, 0, 0, 0, 26, 108, 117, 99, 111, 117, 136, 156, 134, 154, 154, 156, 160, 141, 147, 156, 178, 0], [3, 0, 0, 0, 0, 0, 0, 21, 53, 92, 117, 111, 103, 115, 129, 134, 143, 154, 165, 170, 154, 151, 154, 143, 138, 150, 165, 43], [0, 0, 23, 54, 65, 76, 85, 118, 128, 123, 111, 113, 118, 127, 125, 139, 133, 136, 160, 140, 155, 161, 144, 155, 172, 161, 189, 62], [0, 68, 94, 90, 111, 114, 111, 114, 115, 127, 135, 136, 143, 126, 127, 151, 154, 143, 148, 125, 162, 162, 144, 138, 153, 162, 196, 58], [70, 169, 129, 104, 98, 100, 94, 97, 98, 102, 108, 106, 119, 120, 129, 149, 156, 167, 190, 190, 196, 198, 198, 187, 197, 189, 184, 36], [16, 126, 171, 188, 188, 184, 171, 153, 135, 120, 126, 127, 146, 185, 195, 209, 208, 255, 209, 177, 245, 252, 251, 251, 247, 220, 206, 49], [0, 0, 0, 12, 67, 106, 164, 185, 199, 210, 211, 210, 208, 190, 150, 82, 8, 0, 0, 0, 178, 208, 188, 175, 162, 158, 151, 11], [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0], [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0], [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0], [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0], [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0], [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]]}'
