[Bug] Usage chart working in centos linux. about nvitop HOT 11 CLOSED

I can reproduce this inside a CentOS 7 docker container.

from nvitop.

@yinrong Could you try to set LC_ALL before running nvitop? E.g.:

export LC_ALL='C.UTF-8'
nvitop

There is a similar issue #3.

And do you have libncursesw (with w suffix for wide char) installed on your machine? Have a quick check.

from nvitop.

@yinrong Any updates? nvitop requires to set LC_ALL to UTF-8 with libncursesw installed. If you don't have the permission to install libncursesw, you can try:

nvitop -U

from nvitop.

none above is working. I tried.

LC_ALL='C.UTF-8' nvitop -m
LC_ALL='C.UTF-8' nvitop -m -U
yum install ncurses-devel
LC_ALL='C.UTF-8' nvitop -m
LC_ALL='C.UTF-8' nvitop -m -U

@yinrong nvitop -U only uses ASCII characters, that may work. Maybe your Python is not compiled with NCursesW library. Or you are using nvitop in a conda environment. But I'm not really sure.

Please provide more details of your runtime environment. Then we can investigate deeper.

• Terminal emulator and version: [e.g. GNOME Terminal 3.36.2 / Windows Terminal 1.8.1521.0]
• Python version: [e.g. 3.5.6 / 3.9.6]

PYTHON3="$(head -1 "$(which nvitop)" | cut -b3-)"
"${PYTHON3}" -V  # use the python executable you run `pip3 install nvitop` with

EDIT: detect Python interpreter from shebang.

• Python compile options:

# use the python executable you run `pip3 install nvitop` with
"${PYTHON3}" -c 'import sysconfig; [print(k, v) for k, v in sysconfig.get_config_vars().items()]' | grep -i 'curses'
"${PYTHON3}" -c 'import sysconfig; [print(k, v) for k, v in sysconfig.get_config_vars().items()]'

Please paste the output with text in the comment below (not screenshot).

@muzhi1991 As we can see, you are using libncurses installed in conda environment rather than the system's one (under /usr/lib). What's the result for:

head -1 "$(which nvitop)"

Have you set the correct LD_LIBRARY_PATH? Try:

export LD_LIBRARY_PATH="${CONDA_PREFIX}/lib:${LD_LIBRARY_PATH}"
nvitop

Alternatively, you can try:

/usr/bin/python3 -m pip install --user nvitop

and then run

~/.local/bin/nvitop

from nvitop.

• head -1 "$(which nvitop)" outputs, use conda env python.
  #!/data/app/anaconda3/envs/faq-latest/bin/python

then
run LD_LIBRARY_PATH="${CONDA_PREFIX}/lib:${LD_LIBRARY_PATH}" nvitop same result.

@yinrong @muzhi1991 I create a bug fix PR in #15. You try the fix with:

pip3 install git+https://github.com/XuehaiPan/nvitop.git@fix-locale-utf8#egg=nvitop

Let me know if it works for you.

from nvitop.

it works! thank you!

from nvitop.

Thanks for the feedback from @yinrong @muzhi1991! Now the fix is included in tag 0.5.5 and has been pushed to PyPI.
