Store large dictionary to file in Python

由 怎甘沉沦 提交于 2020-12-30 07:44:43
问题 I have a dictionary with many entries and a huge vector as values. These vectors can be 60.000 dimensions large and I have about 60.000 entries in the dictionary. To save time, I want to store this after computation. However, using a pickle led to a huge file. I have tried storing to JSON, but the file remains extremely large (like 10.5 MB on a sample of 50 entries with less dimensions). I have also read about sparse matrices. As most entries will be 0, this is a possibility. Will this reduce

问题 I've just read the following posts on the same topic: Facebook like notifications tracking (DB Design) and Database design to store notifications to users Some solutions were offered but not exactly what I need and how it should be for a Facebook-like notification system. In a notification, we often have some links pointing to the user who took some action, link to a post or video he commented on, link to anything, and ofter we have several links in a single notification. notification -------

Laravel - How to revert local storage symlink and refresh

由 喜欢而已 提交于 2020-12-28 18:28:16
问题 When I save images to storage they show in the storage/app directory, but they don't show in public/storage . I also noticed that a storage/app/public directory seems to have been created which also contains everything within storage/app. I can't work out how I managed to cause this mess, and I think it might make sense to revert these directories to how it should have been to begin with (with a new laravel project), remove any existing symlinks, and start again - does this sound like the

Kubernetes volumes简介

由 こ雲淡風輕ζ 提交于 2020-10-29 11:25:54
Kubernetes volumes简介 　　容器中的磁盘文件生命周期比较短暂，在一些比较复杂的容器应用中会产生一些问题。一、容器crash后，kubelet会重启该容器，但这些文件会丢失掉。二、pod中的多个容器经常需要共享文件。因此，Kubernetes的Volume应然而生，用于解决这些问题。 背景 　　在Docker中，也有 volumes 这个概念，volume只是磁盘上一个简单的目录，或者其他容器中的volume。生命周期也不受管理，并且直到最近他们都是基于本地后端存储的。Docker现在也提供了volume driver，但是现在来说功能也较弱（比如官网提到的Ceph volume driver，现在已经没有维护了）。 　　Kubernetes的volume，有着明显的生命周期——和使用它的pod生命周期一致。因此，volume生命周期就比运行在pod中的容器要长久，即使容器重启，volume上的数据依然保存着。当然，pod不再存在时，volume也就消失了。更重要的是，Kubernetes支持多种类型的volume，并且pod可以同时使用多种类型的volume。 　　内部实现中，volume只是一个目录，目录中可能有一些数据，pod的容器可以访问这些数据。这个目录是如何产生的，它后端基于什么存储介质，其中的数据内容是什么，这些都由使用的特定volume类型来决定。
