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.
