Okay, so I’ve been messing around with BERT lately, trying to fine-tune it for a specific task. I was following some tutorial, and things were going pretty smoothly, I thought. I had my data all prepped, my model loaded, and I was feeling good. I hit run on my training script, and… BOOM. My system totally locked up.
I mean, completely frozen. No mouse movement, no keyboard response, nothing. I’m sitting there staring at the screen like an idiot, wondering what the heck just happened. It wasn’t just a Python crash or some error message I could debug. Nope, the whole machine was toast. I had to do a hard reset – you know, hold down the power button until it finally shuts off. That’s never a good feeling.
First thing I did after rebooting? Check my system resources. I opened up the task manager and, what do you know, my GPU memory was completely maxed out. Seems like BERT, bless its heart, decided to eat up every last byte of VRAM I had available. All the GPU is running at 100% all the time.

So, lesson number one: always monitor your resource usage.
What I Should Have Done:
- Lower the Batch Size: This is the classic culprit. I was probably being too ambitious with my batch size. Smaller batches mean less memory usage, but training might take longer.
- Use Gradient Accumulation: This is a neat trick where you simulate a larger batch size by accumulating gradients over multiple smaller batches.
- Mixed Precision Training: Using float16 instead of float32 can significantly reduce memory usage, with some potential (but often negligible) impact on accuracy.
- Check for Memory Leaks: Sometimes, it’s not the model itself, but some sneaky bug in your code that’s causing memory to pile up.
- The data I pre-processed before may not be the perfect size: So check it again and again.
I restarted my training with a much smaller batch size, and guess what? It ran without a hitch. I also enabled mixed precision training, just to be extra careful. It took a bit longer to train, but hey, at least my computer didn’t turn into a brick again.
So, yeah, that was my “BERT made my computer crash” adventure. It was a good reminder that even with these fancy pre-trained models, you still need to be mindful of your hardware limitations. Don’t be like me – keep an eye on those resources!
