SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps users determine if a marimo notebook can be executed within WebAssembly (WASM) environments, avoiding compatibility issues.

Core Features & Use Cases

  • Dependency Analysis: Checks whether required packages are compatible with WASM via Pyodide.
  • Code Pattern Validation: Identifies potentially incompatible code patterns such as system calls or threading.
  • Use Case: Developers verifying that their machine learning notebook with common libraries can run directly in a browser environment without native dependencies.

Quick Start

Use the wasm-compatibility skill to scan a notebook and obtain a detailed compatibility report, identifying any issues that need fixing.

Frequently Asked Questions about wasm-compatibility

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I check if my Python notebook is compatible with WebAssembly?▼

You can check Python notebook compatibility with WebAssembly by analyzing package support in Pyodide and scanning code for incompatible system calls or threading patterns before browser deployment.

Why does my Python notebook fail to run in a browser WebAssembly environment?▼

Your Python notebook may fail in a browser WebAssembly environment due to unsupported native dependencies in Pyodide or unsafe code patterns like system calls and threading that WASM constraints prohibit.

How do I adapt machine learning notebooks with native dependencies for Pyodide?▼

To adapt machine learning notebooks for Pyodide, evaluate your required packages to verify WASM support and replace incompatible native dependencies with browser-safe alternatives to enable direct execution.

What code patterns cause compatibility issues in WebAssembly notebooks?▼

Unsafe system calls and threading patterns cause compatibility issues in WebAssembly notebooks because they violate WASM constraints and prevent secure browser execution.

Do I need to remove threading from my Python code to run in Pyodide?▼

You need to scan for and adapt threading patterns in your Python code to run in Pyodide, as WebAssembly environments have specific constraints that often restrict native threading operations.
