Question

我正在研究一个简单的MLP，并对此进行了编码：

let inputVal = [];
let facilityArray = [];
let distanceArray = [];
let timeArray = [];
let filteredArray = [];
let sortedArray = [];
let combined = [];
let facAddress = [];
let resultsObject, intDistanceResult;
const resetButton = document.querySelector("#refresh");


// Set data object
const data = {
    from: "xxxxxxxxx",
    // Facility id and address of each location
    select: [6, 8],
    options: {
        skip: 0,
        top: 0,
    },
};

fetchAPI = () => {
    fetch("https://api.quickbase.com/v1/records/query", {
            method: "POST",
            headers: {
                "QB-Realm-Hostname": "xxxxx.quickbase.com",
                "Authorization": "QB-USER-TOKEN xxxxxxxxxxxxxxxxxx",
                "Content-Type": "application/json",
            },
            body: JSON.stringify(data),
        })
        .then(resp => resp.json())
        .then(data => callFetch(data))
        .catch(error => console.log("Error:", error));
    console.log("fetchAPI fired")
};

callFetch = dataObject => {
    console.log("callFetch fired");
    // Map through the data object and grab the facId and address of each location
    const facId = dataObject.data.map(e => e["6"].value);
    const addresses = dataObject.data.map(e => e["8"].value);
    // Create Google Maps distance service instance
    distanceService = new google.maps.DistanceMatrixService();

    for (let i = 0; i < addresses.length; i++) {
        // Add matrix settings object
        distanceService.getDistanceMatrix({
                origins: [inputVal.toString("")],

                avoidTolls: false,
            },
            // Set response and error capture
            (response, status) => {
                if (status !== google.maps.DistanceMatrixStatus.OK) {
                    console.log("Error:", status);
                    const message = document.querySelector("#message");
                    message.innerHTML = `Error: ${status}. Please resubmit.`;
                } else {
                    const distanceResult = response.rows[0].elements[0].distance
                        .text;
                    const timeResult = response.rows[0].elements[0].duration.text;
                    // Convert distanceResult values to integers and push to distanceArray to later sort
                    intDistanceResult = parseInt(distanceResult.replace(/,/g, ""));

    // Grab container div entry point in html

from keras.models import Sequential
from keras.layers import Dense
from keras import Input

def get_stats_model():

    model = Sequential()
    model.add(Dense(12, input_dim=8, activation='relu'))
    model.add(Dense(8, activation='relu'))
    model.add(Dense(1, activation='sigmoid'))
    model.compile(loss='binary_crossentropy', optimizer='adam', metrics=['accuracy'])
    
    return model

只要指标仅为main.py，Wich就能完美运行。尝试同时使用get_stats_model()和'accuracy'时，仅使用'accuracy'或'AUC'，例如：

'AUC'

我收到以下错误：

'mean_absolute_error'

而且我无法弄清楚为什么唯一的指标变化会导致这种错误，并且互联网上似乎没有太多信息。

我的软件包版本为：

from keras.models import Sequential
from keras.layers import Dense
from keras import Input

def get_stats_model():

    model = Sequential()
    model.add(Dense(12, input_dim=8, activation='relu'))
    model.add(Dense(8, activation='relu'))
    model.add(Dense(1, activation='sigmoid'))
    model.compile(loss='binary_crossentropy', optimizer='adam', metrics=['AUC'])
    
    return model

谢谢。

创建Virtual Environment和

Importing Keras 使用代码from tensorflow import keras

已解决了该问题。（摘自水滴和Aniket Bote）。

model.compile（）对于除“准确性”指标以外的所有指标均失败
