將圖像預測結果轉換成JsonValue
PredictionResult取得結果作為JsonValue
{"blocks":"<xml xmlns=\"https://developers.google.com/blockly/xml\"><block type=\"TeachableMachine_ImagePredictionResult_getResultAsJsonValue\"><value name=\"this\"><block type=\"variables_get\"><field name=\"VAR\">predictionResult</field></block></value></block></xml>"}
這積木是用作將圖像預測結果轉換成JsonValue。
參數：模型預測結果（從Teachable Machine的姿勢模型）
輸出：Json Value
示例代碼：
