We need to centralize the version definition in `datafog/__about__.py`. + +**Tasks:** +1. Ensure `datafog/__about__.py` exists and contains a `__version__` string variable (e.g., `__version__ = "4.1.0"`). +2. Modify `setup.py` to read this `__version__` variable from `datafog/__about__.py`. Common patterns involve reading the file and executing its content in a temporary namespace or using regular expressions. +3. Remove any hardcoded `version` assignment within `setup.py` itself. +4. Verify that `pip install .` and building distributions (`sdist`, `wheel`) correctly pick up the version from `__about__.py`. + +**Acceptance Criteria:** +- The package version is defined *only* in `datafog/__about__.py`. +- `setup.py` successfully reads the version from `__about__.py` during installation and build processes. +- Running `import datafog; print(datafog.__version__)` (if applicable) shows the correct version. + +--- + +## Ticket 2: Remove Runtime Dependency Installations + +**Title:** Remove `ensure_installed()` runtime `pip install` calls + +**Description:** +The codebase currently uses functions like `ensure_installed()` that attempt to `pip install` missing dependencies at runtime. This practice is unreliable, can hide dependency issues, slow down startup, and interfere with environment management. We must remove this pattern and adopt a "fail fast" approach. + +**Tasks:** +1. Identify all code locations where runtime `pip install` commands are executed (e.g., calls to `ensure_installed`, `subprocess.run(['pip', 'install', ...])`). +2. Remove these runtime installation calls entirely. +3. Replace them with standard `import` statements. If an `ImportError` occurs, the program should exit gracefully, clearly stating which dependency is missing and how to install it (e.g., "Please install the 'X' package: pip install datafog[feature]"). +4. Ensure all necessary dependencies are listed correctly in `setup.py`'s `install_requires` or `extras_require`. + +**Acceptance Criteria:** +- No code attempts to install packages using `pip` or similar mechanisms during program execution. +- If an optional dependency (part of an `extra`) is needed but not installed, the program raises an `ImportError` with a helpful message instructing the user how to install the required extra. +- Core dependencies listed in `install_requires` are assumed to be present; missing core dependencies will naturally cause `ImportError` on startup. + +--- + +## Ticket 3: Define and Document Setup Extras for OCR + +**Title:** Document OCR/Donut extras in `setup.py[extras_require]` + +**Description:** +The project offers optional OCR functionality using Tesseract and/or Donut models, which have their own dependencies. These optional dependencies need to be formally defined using `extras_require` in `setup.py` and documented for users. + +**Tasks:** +1. Identify all dependencies required *only* for Tesseract functionality. +2. Identify all dependencies required *only* for Donut functionality. +3. Define appropriate extras in the `extras_require` dictionary within `setup.py`. Suggestions: + * `'ocr': ['pytesseract', 'pillow', ...]` (for Tesseract) + * `'donut': ['transformers[torch]', 'sentencepiece', ...]` (for Donut) + * Optionally, a combined extra: `'all_ocr': ['pytesseract', 'pillow', 'transformers[torch]', 'sentencepiece', ...]` or include dependencies in a general `'ocr'` extra if they don't conflict significantly. +4. Update the `README.md` and any installation documentation (e.g., `docs/installation.md`) to explain these extras and how users can install them (e.g., `pip install "datafog[ocr]"` or `pip install "datafog[donut]"`). + +**Acceptance Criteria:** +- `setup.py` contains an `extras_require` section defining keys like `ocr` and/or `donut`. +- Installing the package with these extras (e.g., `pip install .[ocr]`) successfully installs the associated dependencies. +- Documentation clearly explains the available extras and the installation commands. +- Core installation (`pip install .`) does *not* install the OCR-specific dependencies. + +--- diff --git a/setup.py b/setup.py index ffdca1a4..0031e231 100644 --- a/setup.py +++ b/setup.py @@ -1,11 +1,16 @@ from setuptools import find_packages, setup +import os # Read README for the long description with open("README.md", "r") as f: long_description = f.read() -# Use a single source of truth for the version -__version__ = "4.0.0" +# Use a single source of truth for the version - read from datafog/__about__.py +about = {} +here = os.path.abspath(os.path.dirname(__file__)) +with open(os.path.join(here, 'datafog', '__about__.py'), 'r') as f: + exec(f.read(), about) +__version__ = about['__version__'] project_urls = { "Homepage": "https://datafog.ai", From ca7b967f87da1bf0f6811c91463aa6347c21de0e Mon Sep 17 00:00:00 2001 From: Sid Mohan Date: Sat, 26 Apr 2025 15:45:22 -0700 Subject: [PATCH 02/17] feat: Implement Ticket 2 (remove runtime installs) and define extras --- .../image_processing/donut_processor.py | 29 ++++++------ .../spark_processing/pyspark_udfs.py | 46 +++++++++---------- datafog/services/spark_service.py | 43 +++++++++-------- setup.py | 35 ++++++++++---- 4 files changed, 87 insertions(+), 66 deletions(-) diff --git a/datafog/processing/image_processing/donut_processor.py b/datafog/processing/image_processing/donut_processor.py index b3554140..ba26907f 100644 --- a/datafog/processing/image_processing/donut_processor.py +++ b/datafog/processing/image_processing/donut_processor.py @@ -19,6 +19,20 @@ from .image_downloader import ImageDownloader +# Attempt imports and provide helpful error messages +try: + import torch +except ModuleNotFoundError: + raise ModuleNotFoundError( + "torch is not installed.
