hermetic CUDA and hermetic Python is now available for Tensorflow, a lot of the
requirements installed on the original container can be removed to reduce the
footprint of the container and make it more reusable across different ML

Estas variables de entorno solo pueden manejar strings de texto, ya que son externas a Python y tienen que ser compatibles con otros programas y el resto del sistema (e incluso con diferentes sistemas operativos, como Linux, Windows, macOS).

Eso significa que cualquier valor leído en Python desde una variable de entorno será un `str`, y cualquier conversión a un tipo diferente o cualquier validación tiene que hacerse en código.
