"""
Logs API usage(module and name) within an organization.
In a large ecosystem, it's often useful to track the PyTorch and
TorchVision APIs usage. This API provides the similar functionality to the
logging module in the Python stdlib. It can be used for debugging purpose
to log which methods are used and by default it is inactive, unless the user
manually subscribes a logger via the `SetAPIUsageLogger method <https://github.com/pytorch/pytorch/blob/eb3b9fe719b21fae13c7a7cf3253f970290a573e/c10/util/Logging.cpp#L114>`_.
Please note it is triggered only once for the same API call within a process.
It does not collect any data from open-source users since it is no-op by default.
For more information, please refer to
* PyTorch note: https://pytorch.org/docs/stable/notes/large_scale_deployments.html#api-usage-logging;

Implements the Stochastic Depth from `"Deep Networks with Stochastic Depth"
<https://arxiv.org/abs/1603.09382>`_ used for randomly dropping residual
branches of residual architectures.

Args:
input (Tensor[N, ...]): The input tensor or arbitrary dimensions with the first one
being its batch i.e. a batch with ``N`` rows.
p (float): probability of the input to be zeroed.
mode (str): ``"batch"`` or ``"row"``.
``"batch"`` randomly zeroes the entire input, ``"row"`` zeroes
randomly selected rows from the batch.
training: apply stochastic depth if is ``True``. Default: ``True``
