[docs]def set_dump(target, enabled=True):
"""
Enable or disable dump for the `target` and its contents.
`target` should be an instance of :class:`mindspore.nn.Cell` or :class:`mindspore.ops.Primitive` .
Please note that this API takes effect only when Synchronous Dump is enabled and the `dump_mode`
field in dump config file is ``"2"`` . See the `dump document
<https://www.mindspore.cn/docs/en/r2.4.1/model_train/debug/dump.html>`_ for details.
The default enabled status for
a :class:`mindspore.nn.Cell` or :class:`mindspore.ops.Primitive` is False.
Note:
1. This API only supports being called before training starts.
If you call this API during training, it may not be effective.
2. After using `set_dump(Cell, True)` , operators in forward and backward
computation (computation generated by the grad operations) of the
cell will be dumped.
3. For :class:`mindspore.nn.SoftmaxCrossEntropyWithLogits` layer, the forward
computation and backward computation use the same set of
operators. So you can only see dump data from backward computation.
Please note that :class:`mindspore.nn.SoftmaxCrossEntropyWithLogits` layer will also use
the above operators internally when initialized with `sparse=True` and
`reduction="mean"` .
Args:
target (Union[Cell, Primitive]): The Cell instance or Primitive instance
to which the dump flag is set.
enabled (bool, optional): ``True`` means enable dump, ``False`` means disable dump.
Default: ``True`` .
Supported Platforms:
``Ascend``
Examples:
.. note::
Please set environment variable `MINDSPORE_DUMP_CONFIG` to the dump config file and set `dump_mode` field
in dump config file to 2 before running this example.
See `dump document <https://www.mindspore.cn/docs/en/r2.4.1/model_train/debug/dump.html>`_ for details.
