这是我的多项式回归机器代码，最后我想测试一个随机数 reg.predict([ 这里 ... ])
但是程序给了我这个错误： 找到带有 dim 4 的数组。预期为 LinearRegression <= 2. help me please ...
predict = reg.predict(final2)
r2 = r2_score(test_y,predict)
print('R2Score :',r2)
print('percent :',int(r2*100),'%')
print('++++++++++++++++++++++++++++++++++++++++++++++++++++++')
a1 = input('Press enter to continue ...')
print('++++++++++++++++++++++++++++++++++++++++++++++++++++++')
x = 10
x = numpy.asanyarray(x)
hp = degree.fit_transform(x.reshape(-1,1))
zf = reg.predict([[hp]])
print(zf)
请帮我找到正确的代码行...
