Troubleshooting Your Failed Castles Classifier Training

Hey there, sorry to hear your Castles classifier (ID: Castles_1969040174) keeps failing to train. Since you’ve already checked image size limits and the minimum number of images per class, let’s go through other common pitfalls that might be causing the issue:

Valid Image Formats & Integrity
Make sure all images are in supported formats (typically JPEG, PNG—avoid TIFF, BMP, or PNGs with alpha channels unless your platform explicitly allows them). Also, scan for corrupted images: if even one file in either ZIP is unreadable or partially damaged, it can crash the training process. Try re-opening every image to confirm they load properly.
Class Label Consistency & Accuracy
Double-check that your two ZIP files map to distinct, non-overlapping classes. For example, if one is labeled "castle" and the other "non-castle", ensure no images are misassigned (e.g., a castle photo accidentally in the non-castle zip). Inconsistent or mixed labels will break model training.
ZIP File Structure & Naming
Verify that your ZIPs have a flat structure—images should be in the root of the archive, not nested inside subfolders. Many training platforms can’t traverse nested directories to find images. Also, avoid special characters, spaces, or non-ASCII characters in filenames; stick to alphanumeric names (e.g., castle_01.jpg instead of 城堡 1.png).
Image Diversity & Resolution
Some platforms require a minimum image resolution (e.g., at least 200x200 pixels) to extract meaningful features. Additionally, ensure your training samples have diversity: don’t use 10+ photos of the exact same castle from the same angle/lighting. The model needs varied examples to learn generalizable patterns.
ZIP Archive Integrity
Even if the total size is under limits, re-extract your ZIPs to confirm all files are present and intact. Sometimes compression errors can lead to missing or corrupted files. Also, use standard ZIP compression (not RAR, 7Z, or other formats) since many visual recognition APIs only support standard ZIP.
