FileNotFoundError and subprocess.CalledProcessError in dreambooth colab

[loliana232]

I'm trying to use dreambooth on colab, I use SD 1.5 as a base model and 1024px for resolution, suddenly I got this error during the training process (I tried many times)

Note* when I changed the resolution to be 512px for example I didn't get this error, so I need to know what the problem is plz 🙏

check the file "owalnfiwp-(495).png", it's causing the error

No, I tried many times, but every time it gives me the same error with a different photo, the path is correct and the photo exists in the folder, I don't know where's the problem ??

try a different smaller dataset to make sure the issue doesn't come from the dataset
