在“第 3 章”和“创建第一个深度学习 Web 应用”中,我们看到了如何使用 Python 编写 Flask API,我们看到了如何在 Web 应用中使用该 API。 现在,我们知道 API 与语言库的区别以及使用 API的重要性。 我们熟悉一些顶尖组织提供的各种深度学习 API。 在接下来的章节中,我们将了解如何使用这些 API 来构建...
Python是解释型语言,没有严格意义上的编译和汇编过程。但是一般可以认为编写好的python源文件,由python解释器翻译成以.pyc为结尾的字节码文件。pyc文件是二进制文件,可以由python虚拟机直接运行。 Python在执行import语句时,将会到已设定的path中寻找对应的模块。并且把对应的模块编译成相应的PyCodeObject中间结果,然后创建...
