如您所知,每种编程语言都会遇到很多错误,有些是在运行时,有些是在编译时。 Python 在使用 numpy 库时有时会遇到数组错误。 当我们在 numpy 中传递一维数组而不是二维数组时,会发生错误ValueError: Expected 2D array, got 1D array instead。 Python 中的 Numpy 数组 ...
I am trying to concatenate a 1D into a 2D array. I'd like to avoid doing a loop as it's very computer intensive if my array lengths are greater than 1000. I have tried vstack, stack and concatenate with no success. import numpy as np array_a = np.array([1,2,3]) array_b = ...

今天在找问题的时候发现了一个小坑。 in_array定义: 看一组代码 你们觉得输出都会输出什么。可以先自己判断一下。 注意改变$strict而导致返回结果不同的代码。 没有强调类型前 $strict = false 强调类型后 $strict = true $a = in_array(0, [‘a’, ‘b’]); $a1 = in_array(0...ABAP...
(使用array.reshape(-1, 1)重新调整你的数据) 原错误代码: data['标准化累计票房'] = scaler.fit_transform(data['累计票房']) 修改后: data['标准化累计票房'] = scaler.fit_transform(data['累计票房'].reshape(-1,1)) 如果是python3这里可能会出现警告:FutureWarning。因为reshape方法在后续会取消,所以...
I think you're using a new scikit-learn version and it's throwing an error because in the new version everything has to be a 2d matrix, even a single column or row. It even says: Reshape your data either using array.reshape(-1, 1) if your data has a single feature or array.resh...
