pn[j, 1:-1] = solve_banded((1, 1), banded_matrix, 这行代码出现报错， line 54, in <module> pn[j, 1:-1] = solve_banded((1, 1), banded_matrix,

根据你提供的信息来看，似乎是 `solve_banded` 函数的使用出现了问题。具体来说，可能是以下几种情况之一：

1. 参数传递错误：`solve_banded` 函数需要三个参数，分别是带状矩阵的带宽、带状矩阵本身以及等式右侧的向量。请检查你传递的参数是否符合要求，尤其是带状矩阵的维度是否正确。

2. 数值计算错误：`solve_banded` 函数使用的是带状矩阵求解线性方程组的方法，可能会涉及到数值计算方面的问题。请检查你的带状矩阵是否满足条件，例如是否奇异或者是否有较大的条件数。

3. 模块导入错误：`solve_banded` 函数需要从 `scipy.linalg` 模块中导入。请检查你的代码是否正确导入了该模块。

希望我的回答能够帮到你！如果还有其他问题，请继续提问。

这个错误表明您尝试安装的环境中缺少一些包或版本不匹配。您可以尝试使用以下命令更新您的conda环境：

conda update --all

如果仍然出现问题，请尝试使用以下命令安装缺少的包：

conda install joblib=1.1.0 networkx=2.7.1 typing_extensions=4.1.1 matplotlib-base=3.5.1

如果您使用的是虚拟环境，请先激活该环境再执行上述命令。
