确实,networkx 模块中没有名为 to_numpy_matrix 的方法。在较新版本的 networkx 中,一些与矩阵转换相关的功能已经发生了变化。 提供替代方案: 为了将 networkx 图转换为 NumPy 矩阵,你可以使用 networkx 的adjacency_matrix 方法,该方法返回一个 SciPy 稀疏矩阵。然后,你可以使用 SciPy 的相关函数将这个稀疏矩阵转换...
添加列的方法是使用 numpy.insert 函数。该函数的第一个参数是要添加元素的数组,第二个参数是要插入的位置。第三个参数是要插入的元素。以下示例在矩阵的第三列后面插入了一列:new_col = [7,8] # 需要添加的新列 mat = np.insert(mat, 2, new_col, axis=1) # 在第三列后插入新列 print(mat) ...
Write a NumPy program to convert a vector of integers into their binary representations as rows of a matrix using np.binary_repr. Create a function that maps each integer in an array to an 8-bit binary vector and stacks the results. Implement a solution that uses vectorized operations to co...
