1. Python: In Python, the pickle library provides the save function. It allows you to save any serializable Python object to a file. The basic syntax is as follows: import pickle data_to_save = [1, 2, 3, 4, 5]
The optional arguments(可选参数) cmp, key, and reverse have the same meaning as those for the list.sort() method (described in section Mutable Sequence Types). cmp specifies(指定) a custom comparison function of two arguments (iterable(可迭代的) elements) which should return a negative(复数)...

Numpy save is a function from the Numpy package forPython. What this function does is simple: Numpy savesavesyour Numpy data to a file that can be stored on your computer and shared with others. Specifically,np.save()saves Numpy arrays as a binary file with the ending.npy. ...
# Load all tensors onto the CPU, using a function torch.load('tensors.pt', map_location=lambda storage, loc: storage) # Load all tensors onto GPU 1 torch.load('tensors.pt', map_location=lambda storage, loc: storage.cuda(1)) ...
In this example, we create a directory namedproject_images/and save an image aschicago_saved.jpgin that directory. Theos.makedirsfunction ensures that the directory exists before saving the image. Conclusion In this tutorial, I explained how tosave images in Pythonusing various libraries like Pillo...
二、insert可以一次性插入一个列表，而不用遍历，效率高， save则需要遍历列表，一个个插入。看下这两个函数的原型就清楚了，直接输入函数名便可以查看原型，下面标红的部分就是实现了循环，对于远程调用来说，是一性次将整个列表post过来让mongodb去自己处理，效率会高些 > db.user.insert function (...
