Hi, what do you mean by stuck here? Is the Python still running? Or it crashes?

kukugpt commented 3 months ago

python is running but can not obtain the result

kukugpt commented 3 months ago

This problem seems to be a problem in NoiseTexturize, when exec "augmentations/noisetexturize.py", line 74, in noise result = np.random.normal(0, sigma, size=(ysize, xsize)"

kukugpt commented 3 months ago

it made by turbulence_range=(1,4), which I have made a pull request

kwcckw commented 3 months ago

Thanks, i was able to identify the root cause and it's due to an infinity loop caused by ratio = (ratio // turbulence) or 1. So turbulence must > 1, else ratio will never == 1. I will push a patch shortly.
