[docs]def extension_context(extension_name='cpu', **kw):
"""Get the context of the specified extension.
All extension's module must provide `context(**kw)` function.
Args:
extension_name (str) : Module path relative to `nnabla_ext`.
kw (dict) : Additional keyword arguments for context function in a extension module.
Returns:
:class:`nnabla.Context`: The current extension context.
Note:
Deprecated. Use :function:`nnabla.ext_utils.get_extension_context` instead.
Example:
.. code-block:: python
ctx = extension_context('cuda.cudnn', device_id=0)
nn.set_default_context(ctx)
