提供正确导入numpy库及其子模块的方法: 正确导入numpy库及其子模块的方法应该避免直接从子模块中导入__all__,而是应该导入你需要的具体函数或变量。例如: python import numpy as np # 导入numpy.linalg模块中的inv和det函数 from numpy.linalg import inv, det # 使用导入的函数 a = np.array([[1, 2], [...

from sklearn.linear_model import LinearRegression import numpy as np x = np.array([[1], [2], [3]]) y = np.array([1, 2, 3]) model = LinearRegression() model.fit(x, y) print(model.coef_) 6 TensorFlow 描述: TensorFlow 是一个由 Google 开发的开源机器学习库,用于研究和生产中的数...
语句:import numpy as npimport numpy.linalg as nlA=np.arange(1,5).reshape(2,2)变量A生成的是由元素1到5构成的数组。()
from numpy.linalg import solve A = np.array([[1, 2], [3, 4]]) b = np.array([5, 6]) x = solve(A, b) print("解为:", x) ``` 3.随机数生成:numpy提供了丰富的随机数生成函数,如`random.rand()`、`random.randn()`等。 ```python import numpy as np random_array = np.random...
