for (a_val, b_val) in zip(a, b): print(a_val, b_val) 将输出: 1 4 2 5 3 6 创建对象的Copy Python中可以使用通用的copy函数复制一个对象。浅拷贝是通过使用copy.copy调用的: import copy new_list = copy.copy(old_list) 深拷贝: import copy new_list = copy.deepcopy(old_list) 这个St...

MapIterwas removed from the public numpy C-API, so it was not possible to adapt the C-code forAdvancedIncSubtensor1; instead aNotImplementedErroris raised, so this Op defaults to the python implementation, which usesnp.add.at. Dropped support for Python 2 in C code. ...
cmake 和 python 大概代表了新一代跨平台编译工具的两种方向。第一种 (cmake) 是延续并改良传统 automake, autoconf 工具链,将之合为一体,但最终仍然生成 Makefile, Visual Studio 的 .sln,Xcode 的 .xcodebuild 文件,依赖现有编译工具 (make, nmake, vcbuild, xcodebuild) 来编译;第二种则是完全消除现有编...
