para funcionar perfeitamente com seu modelo de incorporação, você deve criar scripts de pré-processamento e pós-processamento. Esses scripts ajudam o.
entenda o formato dos dados que seu modelo espera e produz.
O exemplo a seguir mostra o script de pré-processador do
Azure OpenAI estrutura de solicitação.
(function(inputs) { //// inputs is the capability inputs which contains request.
/* write code here to transform capability input to definition input.
*{
"request": { //request contains rawInput which will be system-provided.
"rawInput": { //rawInput contains passages(Array of text segments), type(Context of the input) and modelId(Name of the embedding model)
"passages": ["Sample text"],
"type": "ingest/query",
"model": "text-embedding-3-large"
},
"providerInput": { //providerInput should be populated using the relevant data from rawInput.passages.
"input": ["Sample text"] //The field name "input" inside providerInput is provider-specific and rawInput.passages should be mapped to the appropriate field expected by your provider
}
}
}
try {
var parsedInputs = JSON.parse(inputs);
var request = parsedInputs.request;
var rawInput = request.rawInput;
var passagesArray = rawInput.passages;
var type = rawInput.type;
if (passagesArray && passagesArray.length > 0) {

}
} catch (ex) {
gs.error("Exception occured while preprocessing of the inputs." + ex);
throw new Error("Exception occured while OE preprocessing of the inputs : " + ex);
}
inputs = parsedInputs;
return inputs;
})(inputs);
