collect_operator_stats

paddle.amp.debugging. collect_operator_stats ( ) [源代码]

上下文切换器能够收集不同数据类型的运算符数量。按照 float32、float16、bfloat16 等四种数据类型进行分类统计数据算子调用次数，在退出 context 时打印。

返回

无返回值

代码示例

import paddle

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

with paddle.amp.debugging.collect_operator_stats():
    # 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.
