  • Checkbox Extraction from PDFs - A Tutorial
    3 projects | dev.to | 16 Jul 2024
    If you carefully think about it, the system that extracts raw text from the PDF needs to both detect and render PDF form elements like checkboxes and radiobuttons in a way that LLMs can understand. In this example, we’ll use LLMWhisperer to extract PDF raw text representing checkboxes and radiobuttons. You can use LLMWhisperer completely free for processing up to 100 pages per day. As for structuring the output from LLMWhisperer, we’ll use GPT3.5-Turbo and we’ll use Langchain and Pydantic to help make our job easy.

    Pydantic: Use Pydantic to declare your data model. This output parser allows users to specify an arbitrary Pydantic Model and query LLMs for outputs that conform to that schema.

  • JSON extra uses orjson instead of ujson
    4 projects | news.ycombinator.com | 5 Jun 2024
    I'm really surprised ijl got angry that his mail was quoted, it looks innocent enough to me.

    For reference it's been edited out here: https://github.com/pydantic/pydantic/issues/589

    But github shows edits, so the edit is meaningless for privacy. Here's the original mail (yes, I'm blatantly ignoring his request to not publish this, I'm just this evil.)

        I've looked into replacing ujson in pydantic with orjson
  • Advanced RAG with guided generation
    2 projects | dev.to | 18 Apr 2024
    First, note the method prefix_allowed_tokens_fn. This method applies a Pydantic model to constrain/guide how the LLM generates tokens. Next, see how that constrain can be applied to txtai's LLM pipeline.
  • utype VS pydantic - a user suggested alternative
    2 projects | 15 Feb 2024
    utype is a concise alternative of pydantic with simplified parameters and usages, supporting both sync/async functions and generators parsing, and capable of using native logic operators to define logical types like AND/OR/NOT, also provides custom type parsing by register mechanism that supports libraries like pydantic, attrs and dataclasses
  • Pydantic v2 ruined the elegance of Pydantic v1

  • Ask HN: Pydantic has too much deprecation. Why is it popular?
    1 project | news.ycombinator.com | 3 Jan 2024
    I like some of the changes from v1 to v2. But then you have something like this [0] removed from the library without proper documentation or replacement, resulting in ugly workarounds in the link that wont' work properly.

  • OpenAI uses Pydantic for their ChatCompletions API

  • 🍹GinAI - Cocktails mixed with generative AI
    3 projects | dev.to | 19 Oct 2023
    The easiest implementation I found was to use a PyDantic class for my target schema — and use that as a parameter for the method call to “ChatCompletion.create()”. Here’s a fragment of the GinAI Python classes used.

  • Show HN: Config-file-validator – CLI tool to validate all your config files
    3 projects | news.ycombinator.com | 29 Sep 2023
    I was expecting this to validate the configuration files are also valid for their use cases, not just valid JSON, TOML, etc.

    If you're looking for that and Python is your jam, the library cerberus[0] is very good at it.

  • Do you think we need an open-source web scraping monitoring tool?
    2 projects | /r/webscraping | 6 May 2023
    I wrote scrapy-test as a proof of concept for validating live pages for scrapy spiders if you're looking for some reference but if you're not using scrapy I'd recommend just adding validation tests using data validation tools like cerberus which is super underrated. I cover popular data validation techniques on this short blog I wrote if you want to learn more.
  • Can you suggest something more to grow in scraping?
    2 projects | /r/webscraping | 10 Jun 2022
    Other than that, have you looked into testing scrapers? Since scrapers are working with highly dynamic data writing good tests is quite a challange. For example, for parser monitoring using cerberus is a very cool tool which allows you to define loose requirements like "phone number should always be 9 numbers" etc.
