enable_operator_stats_collection¶

paddle.amp.debugging. enable_operator_stats_collection ( ) [source]

Enable to collect the number of operators for different data types. The statistical data are categorized according to four data types, namely float32, float16, bfloat16 and others. This function is used in pair with the corresponding disable function.

Examples

>>> 
>>> import paddle
>>> paddle.device.set_device('gpu')

>>> conv = paddle.nn.Conv2D(3, 2, 3)
>>> x = paddle.rand([10, 3, 32, 32])

>>> paddle.amp.debugging.enable_operator_stats_collection()
>>> # AMP list including conv2d, elementwise_add, reshape2, cast (transfer_dtype)
>>> with paddle.amp.auto_cast(enable=True, level='O2'):
...     out = conv(x)
>>> # Print to the standard output.
>>> paddle.amp.debugging.disable_operator_stats_collection()
>>> # <------------------------------------------------------- op list -------------------------------------------------------->
>>> # <--------------- Op Name ---------------- | -- FP16 Calls --- | -- BF16 Calls --- | --- FP32 Calls--- | -- Other Calls -->
