# Marker 2.0.0: lesson test 2026-10-11 (partial) Cite: headlesson test:lq2atao — Marker 2.0.0, 2026-10-11: 2/4 lesson steps passed, then stopped (operator record). On 2026-10-11, the headlesson operator ran this lesson with Marker 2.0.0 (macOS26.5.2 arm64; Python3.11.13 disposable venv; wheel-only PyPI installation; no LLM use); the first 2 of 4 steps passed, then it stopped: Step3 conversion needs additional artifacts/models; exact marker_single ./sample.pdf first requests missing official font. Safety guard blocked this HTTP request before sending; no output created. Model download not performed. The final Next step is advice and was not run. An independent check (revision 3fadc9d) covered: Independent trial and audit up to install and help; the conversion step's font download was stopped by a guard and produced no output. Its limits: Bounded to the stopping point. Conversion after font and model preparation is unverified. This is the operator's own run, not a vendor claim. Not measured: no conversion output was produced, so extraction fidelity is untested; conversion after the font and model download; the optional --use_llm path. https://headlesson.com/tests/lq2atao Record test:lq2atao. Question: Convert an owner-chosen local PDF without enabling optional remote LLM processing. ## Answer On 2026-10-11, the headlesson operator ran this lesson with Marker 2.0.0 (macOS26.5.2 arm64; Python3.11.13 disposable venv; wheel-only PyPI installation; no LLM use); the first 2 of 4 steps passed, then it stopped: Step3 conversion needs additional artifacts/models; exact marker_single ./sample.pdf first requests missing official font.

Safety guard blocked this HTTP request before sending; no output created. Model download not performed. ## Lesson steps and what happened - 1. [passed] pip install marker-pdf - 2. [passed] marker_single --help - 3. [stopped here] marker_single ./sample.pdf - 4. [not run] Inspect the generated output against the source PDF. ## Next (advice, not tested) Next: Select the real PDF and destination, run marker_single , and compare text, tables and equations with the original. Choose --output_format json for structured output; only enable --use_llm after agreeing on provider, data transfer, cost and model-weight terms. ## Cautions recorded with the lesson These notes come from the lesson. Some describe failures seen in tests; others are general cautions. Each one is not a separately tested result. - Python 3.10 or newer, PyTorch and an owner-provided local sample are prerequisites. - Apache-2.0 and free code use do not establish unconditional rights to model weights. Modified model-weight terms and paid commercial licensing may apply. - The optional --use_llm path can incur provider costs; the initial conversion steps do not enable it. Next treats LLM use as optional and requires the user's data-transfer, cost and model-term decision. - The bundled REST server supports fewer flags than CLI/SDK and omits --use_llm and --disable_ocr. - Conversion output is not independent evidence of transcription accuracy. - Confirm: Check output location, recognition quality on this document, provider credentials/costs and applicable model-weight terms; optional LLM use is not an accuracy guarantee. ## What this record does not show - Steps after step 2 were not completed in this run. - Not measured in this run: no conversion output was produced, so extraction fidelity is untested. - Not measured in this run: conversion after the font and model download. - Not measured in this run: the optional --use_llm path. - Whether an agent new to this tool can use it from this record alone (the operator wrote and ran the lesson). - Comparisons between models or clients. - Production use, accounts, or real customer data. - Behaviour of the latest version (the test is tied to the version and date below). - The final "Next" step is advice and was not part of the test. ## Primary record Operator record: a past lesson trial (legacy). It is not claimed to meet level L1 of run-task-contract/0.1.0. ## Independent check Independent check (revision 3fadc9d6215b): Independent trial and audit up to install and help; the conversion step's font download was stopped by a guard and produced no output. Limits: Bounded to the stopping point. Conversion after font and model preparation is unverified. ## Evidence A non-public test report exists and is not published, so third parties cannot check it directly. ## Retrieve over MCP `headlesson_get id="app:marker" sections ["lesson","gotchas"]` on https://mcp.headlesson.com/mcp ## Source version This page is built from the catalog record app:marker at revision f7fe23dbe39f. It is not rewritten when the current lesson changes; a new test gets a new record ID. ## Sources (lesson text at the fixed revision) Each line names fields of this page (as JSON pointers into the .json version) and where they come from. Labels without a link are non-public sources. Fields not listed (such as test results) are the headlesson operator's own observations. - /question, /steps/3/step, /cautions/items/0, /cautions/items/4: headlesson editorial judgement (checked 2026-10-09, inferred, editorial) - /steps/0/step, /steps/1/step, /steps/2/step: [https://github.com/datalab-to/marker/blob/master/README.md](https://github.com/datalab-to/marker/blob/master/README.md) (checked 2026-10-09, primary, editorial) - /next_advice, /cautions/items/5: [https://raw.githubusercontent.com/datalab-to/marker/master/README.md](https://raw.githubusercontent.com/datalab-to/marker/master/README.md) (checked 2026-10-10, inferred, editorial) - /cautions/items/1, /cautions/items/3: [https://github.com/datalab-to/marker/blob/master/README.md](https://github.com/datalab-to/marker/blob/master/README.md) (checked 2026-10-09, primary, official) - /cautions/items/2: [https://github.com/datalab-to/marker/blob/master/README.md](https://github.com/datalab-to/marker/blob/master/README.md) (checked 2026-10-10, inferred, editorial) ## Corrections None.
