taxdummy=pd.get_dummies(data['TAX CLASS AT PRESENT'])
boroughdummy=pd.get_dummies(data['BOROUGH'])
x = np.array(data['LAND SQUARE FEET'])
x1= np.array(data['GROSS SQUARE FEET'])
x2= np.array(data['BLOCK'])
x3= np.array(data['LOT'])
X = np.column_stack((x,x1,x2,x3,boroughdummy,taxdummy))
我想保留原始标签x='LAND SQUARE FEET' x1='GROSS SQUARE FEET'等但不是0,1,2,3 ...
答案 0 :(得分：0)
如果您想拥有原始列标签，则不应使用numpy get('/login',
validate,
changeStuff,
returnResponse
);
function validate(req, res, next) {
//validate logic does something then calls next()
next()
//just like calling changeStuff(req, res, next)
}
function changeStuff(req, res, next) {
//changeStuff logic changes something then calls next()
next()
//just like calling returnResponse(req, res, next)
}
function returnResponse(req, res) {
//will return something and that is the end of the req-res cycle
//there are no more functions to call, if you try to call next()
//you would get an error, because at this point next() would be
//undefined
res.send(req.body)
}
方法。您可以使用pandas column_stack方法连接DataFrames：
