Okay folks, today got super annoying with that dang fft-024 error popping up again during my analysis work. Felt like hitting a brick wall every time the script choked on that error code. Let me walk you through exactly how I wrestled with this beast.
The Head-Scratching Moment
First noticed it when running my usual data processing script. Everything seemed fine until – bam! – console screamed fft-024 at me. Total roadblock. My initial thought? “Not this crap again.” Remembered seeing this nonsense months back but forgot how I fixed it.
What Didn’t Work (Wasted Time Section)
Tried the lazy route first:
- Restarted Python kernel three times like an idiot
- Reinstalled numpy using pip
- Shuffled data files around like playing musical chairs
Got the same stinkin’ error every single run. Even rebooted my entire system praying for magic. Nope. Still blinking that cursed fft-024 at me in red text.
Digging Into the Actual Problem
Finally opened the log files properly instead of skimming. Saw the failure always happened when processing my Thursday sensor data dump. Pulled up that specific dataset and… oh. It was completely empty. Zero bytes. My collection script failed Wednesday night but nobody told me! Classic garbage-in-garbage-out situation.
The Dumbly Simple Fix
Here’s what actually worked:
- Deleted the empty Thursday data file
- Re-ran data collection for missing hours
- Added this sanity check before processing:
if *(filename) == 0: raise ValueError(“Empty file!”)
That last step? Took 30 seconds to add but saved future me from this headache. Script ran smooth as butter afterward.
What I Should’ve Done From Start
Moral of the story? Don’t be impatient like me. Always:
- Check for empty/corrupt inputs FIRST
- Actually read error logs line-by-line
- Add data validation before complex processing
Lost two hours being stubborn. Hope this saves someone else the trouble! Now back to wrangling my next crisis…
