parser failed on Roboflow dataset manifest with missing split counts error

TL;DR

Fix this in the Roboflow dataset manifest by acting on the exact message first: recompute the split counts from the image folders on disk, rewrite the manifest with the counted values, and point the loader at the corrected manifest. Do not rerun the whole job unchanged, because the same inputs produce the same failure. Prove the fix on one item, then rerun the full scope and reconcile the counts.

Use this when

• The operation in the Roboflow dataset manifest fails with this exact message: parser failed on Roboflow dataset manifest with missing split counts error.
• The same failure repeats on retry with unchanged inputs.
• A review, export or check is blocked until this item completes.

Not for this skill when

• The message is a permission or outage notice from the platform. Resolve that first, then return here if this error remains.
• The operation completes and you only disagree with its output. That is a quality review, not this failure.

Steps

1. Reproduce the failure with the smallest scope that still shows it in the Roboflow dataset manifest, and copy the full message plus the item, user or metric involved into the run notes. Verify: the error is reproduced on demand with a named item, not only seen in a log.
2. Apply the specific fix for this error: recompute the split counts from the image folders on disk, rewrite the manifest with the counted values, and point the loader at the corrected manifest. Verify: the loader accepts the manifest and the split sizes match the folders.
3. Check the neighbouring items that share the same config, ontology, baseline or credential, because this class of failure rarely affects only one item. Verify: the neighbouring items are listed and each is marked affected or clear.
4. Rerun the original operation in the Roboflow dataset manifest on the previously failing scope, watching for the same message rather than assuming success from a quiet log. Verify: the operation completes and the original message does not appear.
5. Compare the result counts, decisions or alerts against the source in the Roboflow dataset manifest so a silent partial success is caught before sign off. Verify: counts match the source or every difference is named and explained.
6. Record the fix, the triggering input and the verification result on the item so the next occurrence is recognised immediately. Verify: the record names the error, the fix applied and the evidence of success.

Why it happens

The manifest caches split counts from generation time; moving or adding images afterwards leaves the cached counts describing a different dataset.

How to fix: parser failed on Roboflow dataset manifest with missing split counts error

The how-to phrasing for the same failure in the Roboflow dataset manifest. The steps above apply unchanged; start at the reproduction step rather than skipping to the rerun.

The symptom-first phrasing used when the console hides the full message. Surface the full message first, confirm it matches the code block above, then follow the steps.

Compatibility: the Roboflow dataset manifest at current versions, plus the platform API or console the query names; no extra tooling beyond a text editor and the source system access needed to verify counts.
