Question

我正在尝试使用Python 3运行预测模型。这是代码行。

try:    
    with open("SalePriceModel_3.pkl","rb") as fp :
        loadedModel = pickle.load(fp,encoding="latin-1")
        sys.stdout.write('2')


    xCols = [u'MSSubClass', u'LotArea', u'OverallQual', u'OverallCond', u'YearBuilt',....]


    listVals = list()

    for colName in xCols :
        if colName in inData.keys():
            listVals.append(inData[colName])
        else:
            listVals.append(0)


    salePrice = loadedModel.predict(np.array(listVals).reshape(-1,33))


    return jsonify({'PredictedSalesPrice': salePrice[0]})
except Exception as  e:
    print(e)
    return e;

有人可以指导如何解决这个问题吗？

这是完整的错误消息，包括追溯：
