问题描述

抱歉，这是否更好地属于我上一个问题的页面: np.savetxt触发ValueError.为什么? 但我认为目前我不会再收到任何答复.

Sorry if this better belongs on the page of my previous question: np.savetxt triggers ValueError. Why? but I don't think I'm going to get any more replies there at this point.

allow_pickle建议仍然无效，因此我可以尝试些什么呢?

The allow_pickle suggestions still don't work, so what I can try instead?

还有，泡菜是什么?我只知道它是一种食物.

Also, what's a pickle? I've only ever known it as a type of food.

谢谢

推荐答案

Pickle是一种将python对象转换为字节流的序列化技术.泡菜最常用于分布式环境中的网络通信. 例如，如果您有一个群集，并且想要将特定的python对象从一台计算机传递到另一台计算机，则最常见的方法是对对象进行腌制，将其通过网络，然后在另一台计算机上将其拆开. 它们也可以用作一种压缩技术，以在本地fs上有效保存巨大的python对象. 要使用泡菜，您必须导入库

Pickle is a serialization technique converting python objects into byte streams. Pickles are most commonly used for network communication in a distributed environment. For example,if you have a cluster and you want to pass a specific python object from one machine to another , the most common way to do this is by pickling the object,pass it through the network and then unpickling it on the other machine. They can also be used as a compression technique for efficiently saving a huge python object on your local fs. For using pickles you have to import the library

    import pickle.py

然后允许程序读取/写入腌制的文件

and then allow the program to read/write pickled files

    allow_pickle = true
