PyMOL-RS: Modern molecular visualization in Rust with WebGPU rendering

PyMOL-RS Python Bindings

Python bindings for PyMOL-RS, a modern molecular visualization tool built in Rust with WebGPU rendering.

Installation

pip install pymol-rs

Jupyter Widget

PyMOL-RS includes an anywidget-based widget for interactive visualization in notebooks. Works in JupyterLab, Jupyter Notebook, VS Code, and Google Colab.

pip install pymol-rs[widget]

from pymol_rs.widget import Viewer

view = Viewer()
view.show()
cmd = view.get_cmd()
cmd.fetch("1CRN")
cmd.show("cartoon")
cmd.color("green", "chain A")

Features:

• Fire-and-forget commands — cmd.fetch(), cmd.show(), cmd.color(), etc.
• Synchronous queries — request/response channel for commands that return data
• Local file loading — load structures from the local filesystem into the browser viewer
• Picking support — optional click-to-select atoms (Viewer(picking=True))
• Configurable layout — width and height parameters with sensible defaults
