positional arguments:

:`FILE`: Path to local cuDNN archive file to install
:`VERSION`: Version name of cuDNN you want to install


`activate`
~~~~~~~~~~

`activate` subcommand activates an installed cuDNN.
This command does not download an archive file unlike `install`.

::

   usage: cudnnenv activate [-h] VERSION

positional arguments:
