Required prerequisites

I have read the documentation https://nvitop.readthedocs.io.
I have searched the Issue Tracker that this hasn't already been reported. (comment there if it has.)
I have tried the latest version of nvitop in a new isolated virtual environment.

What version of nvitop are you using?

1.3.1

Operating system and version

Windows 11 Build 10.0.22631.2506

Python environment

C:\>pip install -U nvitop nvidia-ml-py windows-curses

C:\>python -m pip freeze | python -c "import sys; print(sys.version, sys.platform); print(''.join(filter(lambda s: any(word in s.lower() for word in ('nvi', 'cuda', 'nvml', 'gpu', 'curses')), sys.stdin)))"
3.12.0 (tags/v3.12.0:0fb18b0, Oct 2 2023, 13:03:39) [MSC v.1935 64 bit (AMD64)] win32
nvidia-ml-py==12.535.108
nvitop==1.3.1
windows-curses==2.3.2

Problem description

The nvitop starts, thinks for a couple of seconds, and just silently exits on any example at Resource Monitor.
There is no GUI or a text message in the terminal. The terminal or Windows does not crash/fail.

The windows-curses has been updated due to support Python 3.12. So, it seems the issue depends on the windows-curses.

Notes:

All examples at Device and Process Status work as expected.
Both the examples at Qucik Start work as expected too.

Steps to Reproduce

C:>nvitop

Traceback

No response

Logs

No response

Expected behavior

The nvitop should work as resource monitor in Windows similar as shown in the figure at https://user-images.githubusercontent.com/16078332/129374533-fe06c01a-630d-4994-b54b-821cccd0d33c.png

Hi @BigFatBass, could you try to run:

nvitop -1

to verify if this is an issue related to nvitop rather than windows-curses?

Also, have you ever tried to use nvitop with Python 3.11?

Hi Xuehai Pan, please find my two comments below:

All examples at Device and Process Status work as expected.
Here is the output of nvitop -1:

Please note I've updated the NVIDIA driver to 546.01 but it does not matter.

I used nvitop as the monitor with Python 3.11 and I did not observed any problems til Python 3.12. Moreover, there is no an issue in Ubuntu 23.10 (and NVIDIA driver 535) and WSL2 Ubuntu 22.04 with Python 3.12 at the same HW environment.
In any rate, I've installed Python 3.11.6 on the Windows and nvitop under Python 3.11.6.

I successfully ran nvitop in monitor mode with Python 3.11.
Here is the expected output with Python 3.11 in Windows:

@BigFatBass Thanks for the context. The windows-curses upstream added Python 3.12 support yesterday. Seems that this is an upstream issue for windows-curses on Python 3.12.

Also same problem on Windows:

Python 3.11.8 all works
Python 3.12.2 only once ("-1") works, python.exe crashes

Not sure if related, but most of the command-line arguments don't appear to work. Using Python 3.11.8 and pip install nvitop the refresh is always at two seconds, whatever is specified via `--interval X``

I think the problem has been solved since windows-curses 2.3.3 was released on May 9, 2024. In my platform nvitop can be shown correctly now.
