etils (eclectic utils) is an open-source collection of utils for python.

Each top-level submodule is a self-contained independent module (with its own BUILD rule), meant to be imported individually. To avoid collisions with other modules/variables, module names are prefixed by e (arbitrary convention):

from etils import epath  # Path utils
from etils import epy  # Python utils
from etils import ejax  # Jax utils
...

Becauses each module is independent, only the minimal required libraries are imported (for example, importing epy won't suffer the cost of importing TF, jax,...)

• etils.epath: pathlib-like API for gs://, s3://,...
• etils.etree: Tree utils for tf.nest, jax.tree_utils, DeepMind tree.
• etils.enp: Numpy utils.
• etils.ecolab: Colab utils.
• etils.array_types: Typing annotations for jax, numpy,... arrays
• etils.edc: Dataclasses utils.
• etils.epy: Collection of generic python utils.
• etils.eapp: Absl flags/app utils.
• API design guide.

Because each module is independent and require different dependencies, you can select which modules deps to install:

pip install etils[array_types,epath,epy]
