Not specified by the original author.

TL;DR

Error loading state_dict means the checkpoint's keys or shapes disagree with the model built in this process: print the missing and unexpected keys, then fix the usual causes, a wrapper prefix such as module. from distributed training, a different model variant, or a changed layer. Load with strict set to false only as a diagnostic; a resume that silently drops layers is worse than the error.

how to fix 'RuntimeError: Error loading state_dict for ResNet' failure when resuming checkpoint

Use this when

• The run or call fails with this symptom: RuntimeError: Error loading state_dict for ResNet when resuming a checkpoint.
• You are working on resuming PyTorch training from a saved state_dict and the failure repeats on the same run or configuration.
• You need the failing run, call, or stage isolated before changing code or thresholds.

Not for this skill when

• A checkpoint from a genuinely different architecture that should not be forced into this model, where the fix is using the matching model code.
• The error text names a different tool, stage, or root cause. Match the verbatim error first and use that skill.

Steps

1. Load the checkpoint's keys without the model and list them alongside the model's expected keys. Verify: the key sets can be compared directly
2. Classify the differences: a uniform prefix, renamed layers, missing classifier head, or shape mismatches on specific tensors. Verify: the difference pattern is named
3. Apply the matching fix: strip or add the wrapper prefix, build the correct variant, or initialise the changed layer deliberately. Verify: keys align or the exception list is explicit and intended
4. Load with strict enabled and run one batch to confirm the resumed model behaves. Verify: the load succeeds and the batch runs

Variant phrasings

error loading state_dict for resnet resume checkpoint

The verbatim phrasing.

pytorch state_dict missing unexpected keys module prefix

The prefix phrasing.

runtimeerror loading checkpoint model mismatch fix

The mismatch phrasing.

Compatibility: PyTorch checkpoint loading with state_dict strictness

Why it happens

state_dict loading is an exact contract between the saving model and the loading model. Distributed wrappers, refactors, and variant switches all break the contract in patterned ways, and the runtime error aggregates them into one line that hides which pattern occurred.

Edge cases / pitfalls

• Shape mismatches on one layer after a config change, such as class count, need that layer re-initialised, not the whole checkpoint discarded.
• Save checkpoints without the distributed wrapper, or strip prefixes at save time, to keep resumes portable.

TL;DR

Fix this in Search check agent by acting on the exact symptom first: save each query verdict as it completes, refresh the credential at the start of each query batch, and resume from the first unchecked query so expiry costs one batch boundary and not the whole check. Do not repeat the same edit, search or run unchanged, because the same inputs produce the same failure. Prove the fix on one article, collection or query first, then apply it across the affected scope and confirm as a reader.

Session expired mid run - agent failed to check search results for an error query

Use this when

• Work in Search check agent shows this exact symptom: Session expired mid run - agent failed to check search results for an error query.
• The same symptom repeats after a retry with unchanged inputs.
• Readers or support agents are blocked until this item is corrected.

Not for this skill when

• The help center platform itself is down or returning outage notices. Resolve that first, then return here if this symptom remains.
• The content is correct and you only want a style or tone rewrite. That is an editorial pass, not this fix.

Steps

1. Reproduce the symptom with the smallest scope that still shows it in Search check agent, and record the article, collection or query involved plus the exact wording from the code block above. Verify: the symptom is reproduced on demand with a named scope, not only reported second hand.
2. Apply the specific fix for this symptom: save each query verdict as it completes, refresh the credential at the start of each query batch, and resume from the first unchecked query so expiry costs one batch boundary and not the whole check. Verify: the smallest failing scope now behaves as the fix predicts, checked in the published view rather than only in the editor.
3. Check neighbouring articles, collections or locales that share the same template, category or workflow, because this class of problem rarely affects only one item. Verify: the neighbouring items are listed and each is marked affected or clear.
4. Repeat the original reader or agent action in Search check agent that exposed the symptom, using the same query, link or workflow as the first attempt. Verify: the action completes and the original symptom does not appear.
5. Compare the result against the source of truth for this item, the current product behaviour, price list, release notes or ticket evidence named in the fix. Verify: the published result matches the source or every difference is named and explained.
6. Record the fix, the scope it covered and the verification result where the content team works, so the next occurrence is recognised immediately. Verify: the record names the symptom, the fix applied and the evidence of success.

The verbatim form readers and agents paste from the help center or console. Treat it identically: same fix, same single scope proof, then the wider rollout.

The how to phrasing for the same problem in Search check agent. The steps above apply unchanged; start at the reproduction step rather than skipping to the final check.

Search check agent troubleshooting for this symptom

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

Why it happens

Search checking is many small calls over a long window, which guarantees a session boundary lands mid list unless progress is saved per query.

Edge cases

• The symptom appears in one locale, collection or audience view only. Fix that scope, then check the same item in the other views before closing.
• A cached or indexed copy keeps showing the old state after the fix. Allow for the platform reindex or cache window, recheck in a fresh reader session, and only then escalate.
• Two items have near identical titles. Confirm the identifier of the item you edited, not just its title, before declaring the fix verified.

Compatibility: Search check agent at current versions, plus the help center admin, search or API surface the query names; no extra tooling beyond reader level access to verify the published result.
