Kernel Crash

[ddouglas87]

Note: This is three different issues in one. I'm reporting it this way because I don't know if the three issues are connected or not.

First I install polars_talib by doing a %pip install --no-deps polars_talib. Note that I have to do --no-deps because polars_talib puts polars as a prerequisite package, but I'm using the polars-lts-cpu package.

Issue #1: polars_talib installs the polars package, but there are multiple polars packages. pip install polars_talib should not install the polars package.

Issue #2: "'Expr' object has no attribute 'ta'",

    return df.with_columns(
        ADT=adv/(adv+dec)*100,  # Advance Decline Thrust
        UDT=up/(up+down)*100,  # UP/DOWN VOLUME THRUST
        SPT=change_snp*100,  # S&P 500 PRICE THRUST
        total_issues=total_issues,
        minimum_52w=minimum_52week_movement,
        MHL=minimum_52week_movement.ta.ema(10),  # Minimum High Low
    )

This is my first attempt to run .ta.ema(...). Upon running it here is the output I get:

22:10:26.782 [error] Disposing session as kernel process died ExitCode: undefined, Reason: thread caused non-unwinding panic. aborting.

Issue #3: Kernel panics and crashes.

I figured issue #2 was caused by an old version of Polars, so I updated from version polars-lts-cpu~=1.9.0 to polars-lts-cpu~=1.17.1. (Also note I'm running Python version 3.12.7 right now.)

Here's the new kernel panic output:

thread caused non-unwinding panic. aborting.

Note these kernel panics might overlap with the lack of ARM support. Ironically I prefer to use ARM too. I fell back to an older machine which is why I'm using polars-lts-cpu to try it on an Intel x86_64 machine. My Sandy Bridge i5 CPU does not support AVX2 which polars uses. polars-lts-cpu disables AVX2 instructions.
