ItemsView Object not subcriptable

while running putzmain.py, there is an error:

Traceback (most recent call last):
File "C:\Users\Owner\Desktop\putzmain.py", line 215, in
alltemps = np.load('pbarrs.npz').items()[0][1]
TypeError: 'ItemsView' object is not subscriptable

Pieces are correctly placed on wrong side of the Board(Wrong positioning of the board notation)

Pieces are correctly placed but the board should be from 1-8 not 8-1(board flip issue)

Chessputzer on the command line error

I tried to use Chessputzer on the command line, but I got an error:

d:\chessputzer-master>putzmain.py -f board09.png

Several error when running from Python

Traceback (most recent call last):
File "/usr/lib/python3.9/runpy.py", line 188, in _run_module_as_main
mod_name, mod_spec, code = _get_module_details(mod_name, _Error)

File "/home/cesar/Chess/chessputzer/putzmain.py", line 11, in
import cv2
ModuleNotFoundError: No module named 'cv2'

Error when running command line version (putzmain.py)

Traceback (most recent call last):
  File "<frozen runpy>", line 189, in _run_module_as_main
  File "<frozen runpy>", line 112, in _get_module_details
  File "/home/user/programming/chess/putzmain.py", line 216, in <module>
    alltemps = np.load('pbarrs.npz').items()[0][1]
               ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^^^
TypeError: 'ItemsView' object is not subscriptable

This error occurs simply when trying to run the script normally like so:

python3 -m putzmain.py -f board.png -o out.txt

Doesn't recognise default chess.com board at all

The web interface fails to recognise a chess.com board screenshot at all which is surprising to me as I'd assume 99% of images submitted would be from chess.com or lichess.

where to find putznn.py ?

In the file commandlinenn.md there's file putznn.py mentioned briefly.
I wonder, if you could put this file somewhere in the repository, please?

Add castling when possible

When reading a diagram, especially for puzzle ones, one should always assume that castling is possible. I think the FEN should include the castling rights when possible.
