Python Packages Skill

Installation Pattern

Containers run as root. Always use --break-system-packages:

pip3 install --break-system-packages <package>

Common Packages by Category

Data Analysis

pip3 install --break-system-packages pandas numpy openpyxl xlsxwriter
  • pandas: DataFrames, CSV/Excel/JSON I/O
  • numpy: Numerical arrays, linear algebra, statistics
  • openpyxl: Read/write Excel .xlsx files
  • xlsxwriter: Write Excel with formatting

Scientific Computing

pip3 install --break-system-packages scipy scikit-learn matplotlib
  • scipy: Optimization, interpolation, signal processing, statistics
  • scikit-learn: ML models, preprocessing, metrics
  • matplotlib: Plotting (use Agg backend: import matplotlib; matplotlib.use('Agg'))

File Formats

pip3 install --break-system-packages python-pptx python-docx Pillow PyPDF2 pyyaml
  • python-pptx: PowerPoint files
  • python-docx: Word documents
  • Pillow: Image processing
  • PyPDF2 or pypdf: PDF reading
  • pyyaml: YAML parsing

Web & APIs

pip3 install --break-system-packages requests beautifulsoup4 lxml

Geospatial & Domain-Specific

pip3 install --break-system-packages shapely geopandas  # GIS
pip3 install --break-system-packages obspy              # Seismology
pip3 install --break-system-packages rdkit-pypi          # Chemistry (may need conda)
pip3 install --break-system-packages astropy             # Astronomy

Pre-installed Check

Before installing, check what's available:

pip3 list 2>/dev/null | head -40
python3 -c "import pandas; print(pandas.__version__)" 2>/dev/null

Common Issues

  • matplotlib backend: Set matplotlib.use('Agg') before importing pyplot
  • Missing C libraries: apt-get update && apt-get install -y libgdal-dev for geopandas
  • Compilation: Some packages need gcc: apt-get install -y build-essential
  • Timeout: Large packages (torch, tensorflow) may timeout — check if pre-installed first
