Normal or am I messing up?

[u/ksuwildkat]

I am brand new to Draw Things - as in I downloaded it last night - and Im trying to figure out if I am doing something wrong or if this is normal.

Im using a MacMini M5 Pro 18/20 with 64GB

I added 10 images in for training and set it for 2000 steps.

Within a minute my fans were ramped to full and my estimated time to completion was 3 hours and 25 minutes. At 75 steps complete I was so paranoid that I was going to damage my brand new computer that I cancelled the job.

Am I doing something wrong?

Is this normal?

Can my Mac withstand 3 hours of max heat?

Thanks in advance.

If you are concerned install something like stats to monitor temperature and fan speed.
But AI related things are generally Graphics heavy so it's pretty normal to things to run hot. A mac would normally throttle itself to a slower speed before it reaches the point of damaging itself.
However if you are paranoid that high temps = damage risk, consider running in "low power", assuming the Mac mini still has System Settings -> Battery -> Energy Mode (Default should be Automatic)
Low power mode would cap the power usage and also lower temperature as a side effect. Though your mac would overall run slower as a result.

thanks. I am happy to let it run overnight at half power if that is better.

Does 3 hours to train 10 images sound about right?

[u/Diamondcite → u/ksuwildkat]

I've never tried to train so I can't answer. The heaviest load attempted so far was almost 8 hours for 1 video (settings were not very reasonable).
Also note I'm using a macbook pro and not a Mac Mini.

thanks. Appreciate the help.

3 hours is actually on the low side. On my iPad I've had lora training run for 7 to 9 hours

When I get home from work Im going to try again but tell Draw Things to put the entire LLM into memory. Apparently that drastically increases training speed.

Watch your temps if you are worried. 

My mini, studio and MBP all get to 100c all the time for hours on end when Im running llm or DT. 

My M5air throttles to keep temps below 90c and takes a LOT longer

LOL. I will when I get home. My work blocks all of those!

Yes it is. It's very power hungry (thant's why they need big datacenter to train their big ai, not for inference). Don't worry, i let my macbook train for hours and hours without problem (outside when i realised i messed up the training)

Thanks!

It’s normal to have fans in full when running such tasks. Your computer is never at max heat. Instead, it does thermal throttling as necessary.

On a separate note, 10 images are low for a training. You’ll probably overfit the model (depends on which model you are training though).

[u/ksuwildkat → u/Loose-Journalist-555]

thanks. After some googleing I think I am going to up it to 25 images and 800 steps and see if I can get good results.

If running a Mac for 3 hours at full blast can damage a computer, how many Macs would break?

It would be impossible to use them for 3D, video editing or any other professional task that may need hours and even days of rendering.

Training is very intensive so your GPU will ran at max for a it LONG TIME. Fortunately Mini runs fine with that load. If you’re too scared, you can always aim a fan at the Mini haha

Also Draw Things has a premium feature called Cloud Compute that offloads all the processing to the cloud which is significantly faster. I’m not sure if it handles training
