[文档]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 Asynchronous Dump is enabled and the `dump_mode` field in dump config file is "2". See the `dump document <https://www.mindspore.cn/tutorials/ experts/en/r2.0.0-alpha/debug/dump.html>`_ for details. The default enabled status for a :class:`mindspore.nn.Cell` or :class:`mindspore.ops.Primitive` is False. .. warning:: This is an experimental prototype that is subject to change or deletion. Note: 1. This API is only effective for GRAPH_MODE with Ascend backend. 2. This API only supports being called before training starts. If you call this API during training, it may not be effective. 3. After using `set_dump(Cell, True)` , operators in forward and backward computation (computation generated by the grad operations) of the cell will be dumped. 4. 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.
