I think we should make these optional dependencies and just use numpy in the tests. unless we need to use them in the core app.

Nice work on this method of extracting features! It seems more flexible than our current feature extractor. Perhaps we should add a comment in both feature extractors that the other one exists. And eventually update the old one to use this code.
There was a problem hiding this comment.
Claude says: Done in bcd88f3. The two extractors now point at each other and say how they differ. Resnet50TimmClassifier notes the older FeatureExtractor in trapdata/ml/models/tracking.py, and that class now carries a docstring saying it needs a second inference pass over the queue where the classifier route needs none, and that it L1-normalizes its output where the classifier route does not. That normalization difference is the one worth knowing about if anyone ever compares vectors coming from the two sources.
The same commit also changed the method itself. Taking features from the input separately meant running the backbone twice per batch, once for the logits and once for the embedding, so it is now a single forward_with_features() that returns both from one set of feature maps. The logits are unchanged by the split (maximum absolute difference 0.0 against a plain forward pass), and timm's own pre_logits pooling turned out to be identical to the manual adaptive average pool.

Adds include_features and include_logits flags to PipelineConfigRequest (API) and Settings (worker). Adds features field to ClassificationResponse. Makes logits field conditional (default None). Both default to off for backward compatibility and reduced response size.
APIMothClassifier now accepts include_features and include_logits flags. When enabled, predict_batch() extracts features via get_features() and post_process_batch() conditionally includes logits. Both flow through ClassifierResult → update_detection_classification() → ClassificationResponse. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
API endpoint passes both flags from PipelineConfigRequest to classifier. Worker passes both from Settings (AMI_INCLUDE_FEATURES, AMI_INCLUDE_LOGITS env vars) to classifier constructor. No changes needed to _process_batch() since the predict_batch()/post_process_batch() overrides handle the flow.
Tests that features are 2048-dim when enabled, logits present when enabled, both absent when disabled (default), and both present when both flags set. Replaces Mohamed's original tests with opt-in config pattern. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

- Around line 73-79: predict_batch currently returns (logits, features) which
breaks InferenceBaseClass.run() timing (it expects a tensor and uses
len(batch_output) as batch size); change predict_batch in classification.py (the
predict_batch method that calls self.model and self.get_features) to return only
the logits tensor and move feature extraction to a separate method or populate
self.last_features (or leave get_features unused here) so callers that need
features can call get_features(batch_input) explicitly; ensure no callers expect
a tuple from predict_batch and that APIMothClassifier.run() /
InferenceBaseClass.run() continue to receive a tensor for timing.
In `@trapdata/api/tests/test_features_extraction.py`:
- Around line 50-53: Replace the bare assertion of the response status with a
unittest assertion: in the test block that uses self.file_server and calls
self.client.post("/process", json=pipeline_request.model_dump()) (the block that
then constructs PipelineResponse(**response.json())), change the bare "assert
response.status_code == 200" to use self.assertEqual(response.status_code, 200)
so the test uses unittest's assertion style and yields better failure messages.

the
Pipeline API
Feature extraction ran the backbone twice: once through the model for the logits, then again through forward_features for the embedding. Measured with call counters on timm's resnet50, the old path invoked forward_features twice per batch where one pass is enough, doubling classifier cost in exactly the configuration that wants embeddings. Replaces the get_features(input) hook with forward_with_features(input), which returns the logits and the features from a single set of feature maps. The split is exact: logits match a plain forward pass with a maximum absolute difference of 0.0, and timm's own pre_logits pooling matches the manual adaptive average pool the hook used before. Also notes, on each of the two feature extractors in the codebase, that the other exists and how they differ, as asked for in review. Co-Authored-By: Claude <noreply@anthropic.com>
Classification responses have always carried logits. Putting them behind a new include_logits flag that defaults to false would have silently stopped that for every consumer that did not know to ask, including Antenna's class masking, which re-scores classifications from the stored logits and skips any row where they are null. Nothing about adding feature vectors requires taking logits away, so the flag now defaults to on and only turns them off when a caller asks. The flag also now reaches the binary moth/non-moth filter, in both the HTTP API and the worker. It was only ever passed to the terminal classifier, so include_logits=false still returned logits on non-moth detections. Feature vectors are deliberately not passed to the binary filter: its model has no backbone hook and could only return nothing. Co-Authored-By: Claude <noreply@anthropic.com>
Four small defects in how the classifier passes features from predict_batch to post_process_batch: - _last_features was only ever created inside predict_batch, so calling post_process_batch first raised AttributeError. It is now initialised in the constructor. - predict_batch ran under no_grad only on the branch that extracted features, because the decorator sat on the extraction hook. The worker calls predict_batch directly, so the decorator now sits on the method itself and covers both branches. - Asking for features from a model that has no backbone hook returned nothing and said nothing. Six of the ten pipelines are in that position. A new supports_features() classmethod reports it, and the constructor warns. - Logits were copied to the CPU on every batch even when they were about to be discarded. Adds the type hints both overrides were missing, and makes include_features and include_logits keyword-only so they cannot be bound by a stray positional argument. Co-Authored-By: Claude <noreply@anthropic.com>
The pipeline tests exercise the real thing but need model weights, so nothing pinned the mechanics for a developer working offline or for a reviewer reading the diff. Adds a set of tests that build a random-weight resnet50 and check the parts that can silently break: that the backbone runs exactly once whether or not features are requested, that splitting the forward pass leaves the logits unchanged, that features survive the handoff between predict_batch and post_process_batch and are released afterwards, that the defaults are logits on and features off, and which pipelines report that they can extract features. Removes a test whose name and docstring claimed it drove predict_batch and post_process_batch directly when it only re-ran the HTTP pipeline, and drops one that asserted the old logits default. Both are covered above. The pipeline the API tests run against can now be set with AMI_TEST_PIPELINE, so they can be pointed at whichever model is already cached locally. CI keeps the default.

markdownlint MD028 no-blanks-blockquote rule blank line blockquote
💡 Result:
The markdownlint rule MD028, also known as no-blanks-blockquote, triggers when two separate blockquote blocks are separated only by a blank line [1][2]. Rationale This rule exists because Markdown parser behavior is inconsistent in this scenario [1][2]. Some parsers will merge two blockquotes separated by one or more blank lines into a single blockquote, while others treat them as separate, independent blockquotes [1][2]. How to Resolve You can resolve this violation using one of the following methods: 1. Separate the blockquotes with text or another element: If the blockquotes are meant to be separate, ensure there is content (such as a paragraph of text or an HTML comment) between them [2][3]. Example: > This is a blockquote. This is paragraph text. > This is a second blockquote. 2. Merge the blockquotes: If the blocks are intended to be a single, continuous blockquote, include the blockquote symbol (>) on the blank line between them [1][4]. Example: > This is a blockquote. > > This is the same blockquote.

Restrict AMI_TEST_PIPELINE to feature-capable pipelines.
moth_binary is a valid pipeline choice, but this file asserts that it does not support features. If AMI_TEST_PIPELINE=moth_binary, the feature-required integration tests fail instead of running against a locally cached supported model. Reject unsupported selections at module load, or use a supported fallback.

Claude says: CI has gone red on this branch, but not because of anything in it. The model bucket has stopped serving anonymous requests, and every job here fails trying to download weights. All 23 test failures are the same shape, an HTTP 403 fetching a model file, and most are for files this branch never touches — the localization model, the binary classifier's category map, the north-America category map: The An anonymous request returns 403 for every object and for the bucket root, while an authenticated client can list it normally, and the bucket ACL carries only an owner grant with no public-read entry. So the objects are still there; the bucket has lost the public read access that This is worth someone's attention beyond this PR, because it is not confined to it. Every branch's CI will fail this way, and any worker starting on a machine without a warm model cache will fail to download weights. The last green For what it is worth, the tests do pass when the models are reachable. Locally, with a warm cache and That single local failure is The nine tests added in |
Model weights and label maps are fetched from a public object store that moved to a new cluster. Buckets there are namespaced by the tenant that owns them, so every URL needs both a new host and a "<tenant>:" prefix on the bucket name. Until now the old host was written out in full 34 times across three modules, so every download failed and no single place existed to fix it. The base URL is now defined once in trapdata/common/constants.py as OBJECT_STORE_BASE_URL, with MODEL_BASE_URL and IMAGE_BASE_URL derived from it. The model modules interpolate MODEL_BASE_URL instead of repeating the host. Verified by resolving all 32 distinct model URLs and requesting each one anonymously: 30 return content. The two that do not are the UK Turing model and its category map, which are absent from the bucket rather than moved -- the old and new buckets hold identical bytes, so those keys were already missing before the migration.

Summary
A classifier already computes a rich description of every crop it looks at on its way to picking a species, and then throws it away. This branch keeps it. Each classification can now carry the 2048-number feature vector that the model's backbone produced, which is what lets downstream work ask questions the label alone cannot answer: whether two detections on different frames are the same individual, which unlabelled crops look like each other, how a night's captures cluster.
The immediate consumer is Antenna's occurrence tracking, which stores these vectors per classification and compares them across frames to follow an insect through a session. Antenna side: RolnickLab/antenna#1272.
Feature vectors are large, so they are off unless asked for, by request config in the HTTP API or by
AMI_INCLUDE_FEATURESin a worker's environment. Raw logits get the same switch, but they stay on by default: they have always been part of the response and other things already read them.List of Changes

Logits now default to on, where an earlier revision of this branch defaulted them to off. The reasoning:
mainhas always returned logits unconditionally, and Antenna's class-masking re-scores classifications from the stored logits and skips any row where they are null. Defaulting the new flag to false would have silently stopped that working for every consumer that did not know to start asking. Adding feature vectors does not require taking logits away, so the flag defaults to preserving today's behaviour and only turns them off when a caller opts out. Happy to flip it if you would rather the response shrink by default.Related Issues

FeatureExtractorpipeline stage in favour of the classifier-integrated route added here, dropping the pipeline from 5 stages to 4. This branch does the groundwork by making the classifier route single-pass and documenting how the two differ; note that the older stage L1-normalizes its vectors and this one does not, so anything comparing vectors from both will need to account for that.Related PRs
