	void dnnl::graph::set_constant_tensor_cache(int flag)

Control the enabling or disabling of constant tensor cache.

This API must be called once before compilation stage. By default, constant tensor cache is enabled in the library.



.. rubric:: Parameters:

.. list-table::
	:widths: 20 80

	*
		- flag

		- Set to positive value to enable the cache and set to 0 to disable the cache. Negative values are invalid.

.. ref-code-block:: cpp
	:class: doxyrest-title-code-block

	int dnnl::graph::get_constant_tensor_cache()

Return the enabling status of constant tensor cache.
