opentau.utils.import_utils

Utilities for checking package availability and versions.

This module provides functions to check if packages are installed and optionally retrieve their versions without importing them, which is useful for conditional imports and dependency checking.

Functions

is_package_available(pkg_name[, return_version])

Check if a package is available and optionally return its version.

opentau.utils.import_utils.is_package_available(pkg_name: str, return_version: bool = False) → tuple[bool, str] | bool

Check if a package is available and optionally return its version.

Copied from https://github.com/huggingface/transformers/blob/main/src/transformers/utils/import_utils.py

This function checks if the package spec exists and grabs its version to avoid importing a local directory. Note: this doesn’t work for all packages.

Parameters:

• pkg_name – Name of the package to check.

• return_version – If True, return a tuple of (available, version). If False, return only the availability boolean. Defaults to False.

Returns:

If return_version is False, returns a boolean indicating availability. If return_version is True, returns a tuple of (available, version).
