muller-export

name	muller-export
description	Export and integrate MULLER datasets with other formats - Arrow, Parquet, JSON, NumPy, MindRecord. Use when user wants to export data, convert formats, or integrate with other frameworks.
compatibility	Requires Python 3.11+, muller package installed

MULLER Export & Integration

IMPORTANT: How to Use This Skill

DO NOT create new Python files. Always use the existing script:

• Use scripts/export.py for all export and integration operations

Execute the script directly with python3 command. Never write new scripts to the project root.

DEMO MODE: Speed Instructions

When executing operations:

• Run commands immediately without pre-explanation
• Do not summarize or explain results after execution
• Only show the JSON output from the script
• Skip all follow-up suggestions unless user asks

When to Use This Skill

Use this skill when the user wants to:

• Export datasets to Arrow format
• Export datasets to Parquet files
• Export datasets to JSON format
• Convert datasets to NumPy arrays
• Export to MindRecord format (for MindSpore)
• Integrate with PyTorch, TensorFlow, or other frameworks

Available Script

scripts/export.py

Handles export and format conversion operations.

Operations:

• to-arrow - Export to Apache Arrow format
• to-parquet - Export to Parquet files
• to-json - Export to JSON format
• to-numpy - Convert tensors to NumPy arrays
• to-mindrecord - Export to MindRecord format
• get-info - Get export information

Usage:

# Export to Arrow
python3 .claude/skills/muller-export/scripts/export.py to-arrow \
  --path ./my_dataset --output ./output.arrow

# Export to Parquet
python3 .claude/skills/muller-export/scripts/export.py to-parquet \
  --path ./my_dataset --output ./output_dir

# Export to JSON
python3 .claude/skills/muller-export/scripts/export.py to-json \
  --path ./my_dataset --output ./output.json

# Convert tensor to NumPy
python3 .claude/skills/muller-export/scripts/export.py to-numpy \
  --path ./my_dataset --tensor embeddings --output ./embeddings.npy

# Export to MindRecord
python3 .claude/skills/muller-export/scripts/export.py to-mindrecord \
  --path ./my_dataset --output ./output.mindrecord

Quick Reference

Export formats: Arrow (columnar exchange), Parquet (storage/analytics), JSON (web APIs), NumPy (ML frameworks), MindRecord (MindSpore).
