[Python] Python/Oct2Py/Octave Setup Woes

In Windows 10 or 11, I am trying to set up a Python/Oct2Py/Octave environment so that I can write Python scripts that can invoke Octave functionality. I set this up on my own machine, and got it working about a year ago. Now I am trying to replicate this setup, but my notes must be somewhat deficient, as I run into errors doing the simplest tasks. For example, in the Octave CLI, I can run this command:

octave:1> pwd()
ans = C:\Users\bob


In my working Anaconda Powershell, I can run this equivalent:

(base) PS C:\Users\bob> python
Python 3.9.12 (main, Apr 4 2022, 05:23:19) [MSC v.1916 32 bit (Intel)] :: Anaconda, Inc. on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> from oct2py import Oct2Py
>>> o = Oct2Py()
>>> o.pwd()
'C:\\Users\\bob'
>>>


However, in my new setup, I run into problems:

(base) PS C:\Users\rsg> python
Python 3.9.12 (main, Apr 4 2022, 05:23:19) [MSC v.1916 32 bit (Intel)] :: Anaconda, Inc. on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> from oct2py import Oct2Py
>>> o = Oct2Py()
>>> o.pwd()

out[key] = _encode(value, ctf)
File "C:\ProgramData\Anaconda3\lib\site-packages\oct2py\io.py", line 376, in _encode
if isinstance(data, spmatrix):
NameError: name 'spmatrix' is not defined
>>>


In both cases, all the software is the same:

1. Windows 11 Home
2. Anaconda (2022.05 - Python 3.9.12)
3. Oct2Py (installed via "conda install -c conda-forge oct2py")
4. Octave 8.2.0

I cannot figure out what is going on with the new install (I've tried it on three separate machines, and they all fail).
