当用户指定了source_dir,则默认使用/ml/usercode作为工作目录执行command。command="python run.py", image_uri="<ServingImageUri>", requirements=["fastapi","uvicorn", ] )print(inference_spec.to_dict()) 当您需要将额外的数据、代码或模型导入推理服务容器时,可以利用pai.model.InferenceSpec.mount()方法...
Continue The continue statement terminates the current iteration of the statement, skips the rest of the code in the current iteration and the control flows to the next iteration of the loop. Pass As explained above, the pass keyword in Python is generally used to fill up empty blocks and is...
题目地址:https://leetcode.com/problems/flatten-nested-list-iterator/description/ 题目描述 Given a nested list of integers, implement an iterator to flatten it. Each element is either an integer, or a list – whose elements may also be integers or other lists. ...

以下示例显示了存储为两个字节无符号二进制数(typecode "H")的数字数组,而不是通常的Python int对象列表的每个条目通常16个字节: >>> >>> from array import array >>> a = array('H', [4000, 10, 700, 22222]) >>> sum(a) 26932 >>> a[1:3] array('H', [10, 700]) 该collections...
https://leetcode.com/problems/flatten-nested-list-iterator/ 展平嵌套的list。 从调用的方式来看,总会调用到最后,所以在构造函数中递归展开所有的数放到一位数组中。 另一种方式是把nested list压到栈中,需要的时候再从栈中拿。 注意需要调用注释中的isInteger(),getInteger()和getList()三个方法。
