Usage

::

usage: cudnnenv [-h] {install,install-file,activate,uninstall,version,versions,deactivate} ...

positional arguments: {install,install-file,activate,uninstall,version,versions,deactivate}

:install: Install version :install-file: Install local cuDNN file :activate: Activate installed version :uninstall: Uninstall version :version: Show active version :versions: Show avalable versions :deactivate: Deactivate cudnnenv

optional arguments: -h, --help show this help message and exit

install

`install` subcommand installs a given version of cuDNN and activate it.
Use `activate` subcommand to only activate installed version.

::

   usage: cudnnenv install [-h] VERSION

positional arguments:

:`VERSION`: Version of cuDNN you want to install and activate. Use `versions` subcommand to check the available versions.

`install-file`

install-file subcommand installs a given local cuDNN file and activate it. You can only install tar.gz file, can not use deb packages.

::

usage: cudnnenv install-file [-h] FILE VERSION

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:

:`VERSION`: Version of installed cuDNN you want to activate.


`uninstall`

uninstall subcommand uninstalls a given version of cuDNN from your environment.

::

usage: cudnnenv uninstall [-h] VERSION

positional arguments:

:VERSION: Version of cuDNN you want to uninstall.
