并且scipy没有返回正确的答案。那我该怎么办？
代码：
scipy.optimize.minimum这是说成功为假的消息 我做的一切都是正确的我不知道发生了什么
答案 0 :(得分：0)
在以下情况下调试类似的东西很难：
有一些奇怪的设计决定：
然后关于你的观察：
Iterations: 0
Function evaluations: 106
Gradient evaluations: 94
零迭代，同时进行如此多的功能评估是一个非常糟糕的迹象。有些东西很破碎。可能行搜索在上面疯狂，但这只是猜测。
现在什么坏了？：
要做的步骤：
jac=False运行
我想知道为什么你这里没有任何形状错误。当我试图模仿您的输入形状并玩弄样本大小时，我会这样做！
