PyReqify

A lightweight Python module for requirements.txt generation. It efficiently extracts imported modules and generates a requirements.txt file with module versions for .py and .ipynb files in a given directory. Simplify dependency management for your projects!

Features

• 📦 Automatic Module Extraction: Scans .py and .ipynb files in a directory to find all imported modules.
• 🔍 Version Detection: Fetches installed versions of imported modules (maps common aliases to official package names). It also gives the option to includes fetch source python version too.
• 📝 Requirements Generation: Creates a requirements.txt file with all extracted dependencies and the current Python version.

Installation

Clone this repository and install the requirements.

pip install pyreqify

Usage

To use the pyreqify function and automatically create a requirements.txt file:

1. Place all .py and .ipynb files in a folder (e.g., project).
2. Run the function to generate a requirements.txt in the current directory with all extracted dependencies.

pyreqify <source_folder> <destination folder> --include-source-pyversion

generated requirement.txt file

scikit-learn==1.5.1
keras==3.6.0
numpy==2.0.1
pandas==2.2.2
open3d==0.16.1
webcolors==24.8.0
nbformat==5.10.4
matplotlib==3.9.1
typing==3.7.4.3
torch==2.2.2
python==3.10.14

Examples

Example 1: Generate requirements.txt in the current working folder without the Python version.

pyreqify ~/Workspace/project .

Example 2: Generate requirements.txt in the deploy folder, including the Python module versions and Python version in the file.

pyreqify ~/Workspace/project ~/Workspace/project/deploy --include-module-version --include-source-pyversion
