### 类型和验证

这些环境变量只能处理文本字符串，因为它们是外部于 Python 的，并且必须与其他程序和整个系统兼容（甚至与不同的操作系统，如 Linux、Windows、macOS）。

这意味着从环境变量中在 Python 中读取的任何值都将是 `str` 类型，任何类型的转换或验证都必须在代码中完成。

*   TPU Enhancements:
    *   Refactor `TpuClusterResolver` to move shared logic to a separate pip
        package.
    *   Support configuring TPU software version from cloud tpu client.
    *   Allowed TPU embedding weight decay factor to be multiplied by learning
        rate.
*   XLA Support:
