Original GitHub issue: https://github.com/XuehaiPan/nvitop/issues/3

Runtime Environment

Operating system and version: Arch Linux x86_64
Terminal emulator and version: Alacritty 0.8.0 (a1b13e68)
Python version: Python 3.9.6
NVML/CUDA version: nvidia-smi: 465.31 / 11.3
nvitop version/commit: 0.3.5.6
python-ml-py version: 11.450.51
Locale: USA

Current Behavior

After following installation instructions running nvitop command does not work, bash cannot find the command. However, python -m nvitop does work. Added /home/user_name/.local/bin to enable nvitop command to work.
nvitop command prints as expected, however, nvitop -m colored graphs and formatting for CPU and MEM aren't showing correctly.

side x side comparison "nvitop -m"(left) vs "nvitop("right)

Expected Behavior

nvitop install would set up env var so that command works immediately after install
CPU and MEM graphical representation of % used would show and format would match that of nvitop command.

Possible Solutions

nvitop install to check/add env var or ReadMe should note for the end-user to check this
I'm not sure :(

Steps to reproduce

Remove user-added env path, open terminal, and run nvitop
Run nvitop -m or python3 -m nvitop -m

@XuehaiPan commented on GitHub (Jul 20, 2021):

Thanks for the feedback!

For the first issue:

After following installation instructions running "nvitop" command does not work, bash cannot find command.

You shoud add the directory of nvitop's executable in your PATH, usually ~/.local/bin (for installed by pip3 install ...) or /usr/local/bin (for installed by sudo pip3 install ...).

For the second issue:

nvitop command prints as expected, however, nvitop -m colored graphs and formatting for CPU and MEM aren't showing correctly.

As the screenshot you have shown, the monitor mode of nvitop didn't display the box-drawing characters correctly. As Alacritty does support Unicode characters, does your ncurses library support Unicode (pacman -Ql ncurses | grep ncursesw)? nvitop will set the LC_ALL at startup:

b669fa39b1/nvitop/cli.py (L58-L64)

Possible solutions:

set the environment variable LC_ALL='C.UTF-8' or LC_ALL='en_US.UTF-8' in your shell profile.
use nvitop -m -U to use ASCII characters only.

Thanks! I've added your changes to the env path and set the LC_ALL env var and am able to see visualizations as expected!
