[BUG] The conda distribution has TERM-related problems

[Yura52]

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?

1.5.2

Operating system and version

Ubuntu 22.04

NVIDIA driver version

550.163.01

NVIDIA-SMI

Python environment

No environment is needed

Problem description

I use the Ghostty terminal emulator and I have an issue with nvitop described here:
ghostty-org/ghostty#8097

I noticed that there are similar issues in the repository (e.g. #118), but the suggested solution requires patching the terminal-related environment variables, which I would like to avoid. After a quick investigation, it seems that the problem is specifically in the Conda distribution of nvitop, not in Ghostty.

Steps to Reproduce

This works fine:

uvx nvitop

However, this fails:

pixi exec nvitop

Or, if you prefer conda:

conda create -n nvitop-conda-bug -y nvitop
conda run -n nvitop-conda-bug nvitop

Expected behavior

@Yura52, I think it is related to the conda provided Python, not nvitop.

I noticed that there are similar issues in the repository (e.g. #118), but the suggested solution requires patching the terminal-related environment variables, which I would like to avoid.

You may add a per-environment activation script here:

${CONDA_PREFIX}/etc/conda/activate.d/*.sh

for your conda environment. Those files will be sourced when you activate the environment.

For example:

conda activate xxx
echo 'export TERM="xterm-256color"' > "${CONDA_PREFIX}/etc/conda/activate.d/terminfo.sh"
echo 'export TERMINFO="${CONDA_PREFIX}/share/terminfo"' >> "${CONDA_PREFIX}/etc/conda/activate.d/terminfo.sh"

@xhochy Hi! Tagging you as one of the Conda Python feedstock contributors. We are discussing an error where the Conda distribution of Python may be the root cause. Perhaps, you can give us a hint whether this is true and how to fix the issue.

TL;DR

When using the Ghostty terminal emulator and being connected to a remote Linux machine (after configuring terminfo as explained here), the following works:

uvx nvitop

However, the following fails:

pixi exec nvitop

But the following works:

TERM=xterm-256color pixi exec nvitop

That is, the Conda distribution of the nvitop tool fails without patching the TERM environment variable, and @XuehaiPan suggests that specifically the Conda Python interpreter can be the reason.

The issue is quite vague. Do you have an error message or a traceback?

I provided more details here when describing the bug:
ghostty-org/ghostty#8097

Note that at the end of the discussion, I came to the conclusion that specifically the Conda dstribution of nvitop is the issue, then opened this issue, and then the main hypothesis became that the Conda distribution of Python itself is the issue.

I looked into this and the ncurses build on conda-forge, and I'm also a Ghostty user, and for me, it works fine for me. As I cannot reproduce, you will need to fine more debug information on what could possibly go wrong.
