Holle, I want to run:

import arviz

the console return:

UnicodeDecodeError: 'gbk' codec can't decode byte 0xba in position 2367: illegal multibyte sequence

What do I need to do to solve this problem? Looking forward to your answer！

Hi, what python version and arviz version do you have?

[fish-galaxy]

I use the version is python 3.10.9 and arviz 0.16.1

This looks very similar, perhaps identical, to an issue that came up in CI when wrapping arviz with Julia (JuliaRegistries/General#88578 (comment)). Note that the error traces back to the same line of Python code: https://github.com/JuliaRegistries/General/actions/runs/5808545587/job/15745534758#step:16:885 . This was with a fresh Conda environment built with micromamba with only the constraint "arviz >= 0.14.0".

python 3.11.4
arivz 0.16.0

using arivz 0.15 non error

[fish-galaxy]

@sethaxen Thanks, i find arviz can successfully run if the version<0.16.0 when i try to change the version.
@vitwei You can try to ues the arviz0.15.1 or lower version.

[ahartikainen]

How did you install arviz?

Conda or pip?

[lucianopaz]

This also came up here. The issue there was that the user was on windows. The system encoding there isn't utf-8, if I remember correctly it's Latin1, so when they try to read the contents of the file that has utf-8 special characters, the system level encoding can't understand them and errors out. To fix that, you'll need to explicitly pass encoding="utf-8" when calling read_text.

[OriolAbril]

We need to add the encoding argument in

arviz/arviz/utils.py

Line 671 in 6b1b2be

importlib.resources.files("arviz").joinpath(fname).read_text() for fname in STATIC_FILES

then. Thanks @lucianopaz!
