numpy.distutils.ccompiler_opt.CCompilerOpt.feature_ahead#
方法
- distutils.ccompiler_opt.CCompilerOpt.feature_ahead(names)[源代码]#
返回 'names' 中的特征列表,在移除所有隐含特征后保留原始特征。
- 参数:
- 'names': 序列
CPU 功能名称序列(大写)。
- 返回:
- CPU 功能列表,按 'names' 中的顺序排序。
示例
>>> self.feature_ahead(["SSE2", "SSE3", "SSE41"]) ["SSE41"] # assume AVX2 and FMA3 implies each other and AVX2 # is the highest interest >>> self.feature_ahead(["SSE2", "SSE3", "SSE41", "AVX2", "FMA3"]) ["AVX2"] # assume AVX2 and FMA3 don't implies each other >>> self.feature_ahead(["SSE2", "SSE3", "SSE41", "AVX2", "FMA3"]) ["AVX2", "FMA3"]
