[SOLVED] Illegal instruction¶

Context:

Happened when conflict instruction of package dependencies with the current OS.

What error message means is that the execute has some CPU instructions that the CPU that runs it doesn't understand.

Related:

Package Dependencies
OS system

Current meet:

The OS in the deployment OS is Centos7 maybe related to non-updated CPU
The upgrade version of polars greater than 0.19.0
When execute script has related to polars

python3 component/vendor/quote_trading.py -v
# Illegal Instruction

There are various the same issue but at different of package. E.g:

Checkpoint:

[1] Make sure you has the permission of execute script

# For recursive at the deployment folder
chmod R 0777 working-directory/

# Or at the file script level
chmod 0777 working-directory/component/vendor/filename.py

[2] Define your area of error by run line-by-line of the script from the top-to-bottom in the interactive mode.
[3] Then check at the version related level

# Syntax:
# $ python -vc "import <packge>"
python -vc "import polars as pl"

[4] Check your OS CPU

[5] Find the related model that suitable for that OS.

In this case, download polars-lts-cpu instead, follow the comment Polars Issues #2922

[SOLVED] Check version of a target package¶

Detect exist in requirement

cat requirements.txt | grep polars
# 0.19.5

Check in the background versions

python3 -c "import polars; print(polars.__version__)"
# 0.19.5
