AutoMixedPrecisionListsBF16 is a class for fp32/bf16 op types list. The lists are used for an
|
|
algorithm which determines op's execution mode (fp32 or bf16).It can update pre-defined
|
|
fp32 list and bf16 list according to users' custom fp32 bf16 lists.

|
|
Args:
|
|
custom_bf16_list (set): Users' custom bf16 list.
|
|
custom_fp32_list (set): Users' custom fp32 list.
|
|
custom_fp32_varnames (set): Users' custom fp32 variables' names.

|
|
.. code-block:: pycon
