ImportError: cannot import name bmat from scipy.sparse.sputils

这个错误通常是由于你的 Scipy 版本与你的 Numpy 版本不兼容所导致的。你可以尝试以下几个解决方案：

1.更新 Scipy 和 Numpy 到最新版本：

pip install --upgrade scipy numpy

2.降级 Scipy 版本：

pip install scipy==1.1.0

3.卸载 Scipy 和 Numpy 并重新安装：

pip uninstall scipy numpy
pip install scipy numpy

希望这些方法能够解决你的问题。

ImportError: cannot import name 'bmat' from 'scipy.sparse.sputils'

这个错误通常是由于Scipy版本过低导致的。可以尝试升级Scipy到最新版本，或者使用下面的代码解决该错误：

import numpy as np
from scipy.sparse import linalg

# Replace bmat with block_diag in your code
def bmat(blocks):
    return linalg.block_diag(*blocks)

ImportError: cannot import name 'bmat' from 'scipy.sparse.sputils' (C:\Users\LENOVO\anaconda3\lib\site-packages\scipy\sparse\sputils.py)

This error occurs when the Python interpreter is unable to import the 'bmat' function from the 'scipy.sparse.sputils' module. This could be due to a few reasons:

1. The 'bmat' function may have been removed or renamed in a newer version of SciPy. In this case, you should check if your code is compatible with the version of SciPy you are using.

2. There could be an issue with your SciPy installation. Try reinstalling SciPy using pip or conda.

3. There may be a conflict with other modules or packages in your Python environment. Try creating a new virtual environment and installing only the necessary packages for your code to run.

4. There may be a typo or syntax error in your code. Double-check your code to see if there are any mistakes.
