Yes. Low install friction, no mandatory dependencies, active maintenance, permissive licensing, and a modular design that lets you pull in only what you need make this a practical choice for Python developers, especially those in machine learning and scientific computing. The lack of security vulnerabilities and top-5000 popularity tier reinforce its stability.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.11 or later.
- Low friction installation with no runtime dependencies; actively maintained with recent commits and a permissive license.
- The modular design means you install only what you need via optional extras.

What it is and what it does
Etils is a collection of independent utility submodules designed to be imported individually, each providing specialized tools without forcing you to install unrelated dependencies. The package includes tools for pathlib-like access to cloud storage (gs://, s3://), tree utilities for nested structures, numpy and array type annotations, dataclass helpers, and generic Python utilities. Because each submodule is self-contained, importing epy won't pull in TensorFlow or JAX unless you explicitly install those extras.
The package is actively maintained, has no mandatory runtime dependencies, and uses a permissive Apache license. It targets Python 3.11 and later and is positioned for developers working with machine learning frameworks and scientific computing who want lightweight, à la carte utilities rather than a monolithic dependency.
Use it for
- Use etils.epath to work with cloud storage paths (gs://, s3://) with a pathlib-like interface.
- Use etils.etree to manipulate nested structures compatible with tf.nest, jax.tree_utils, or DeepMind tree.
- Use etils.array_types to add type annotations for JAX, NumPy, and other array libraries in your codebase.
- Use etils.edc for dataclass utilities and helpers when building machine learning pipelines.
- Use etils.epy for generic Python utilities without pulling in framework-specific dependencies.
