Train complicated nn models with tf.eager (better with TF2 symbolic support)

问题 Is there (more or less) simple way to write a complicated NN model so it will be trainable in the eager mode? Are there examples of a such code? For example, I want to use the InceptionResnetV2 . I have the code created with tf.contrib.slim . According to this link, https://github.com/tensorflow/tensorflow/issues/16182 , slim is deprecated and I need to use Keras . And I really can't use a slim code for training with eager because I can't take the list of variables and apply gradients (ok, I

F# lazy eval from stream reader?

由 只谈情不闲聊 提交于 2019-12-10 15:18:45
问题 I'm running into a bug in my code that makes me think that I don't really understand some of the details about F# and lazy evaluation. I know that F# evaluates eagerly and therefore am somewhat perplexed by the following function: // Open a file, then read from it. Close the file. return the data. let getStringFromFile = File.OpenRead("c:\\eo\\raw.txt") |> fun s -> let r = new StreamReader(s) let data = r.ReadToEnd r.Close() s.Close() data When I call this in FSI: > let d = getStringFromFile(

Guice eager/lazy singleton instantiations

问题 I'm having some troubles understanding how Guice's singleton instantiations works. I've read the available documentation (here - http://code.google.com/p/google-guice/wiki/Scopes ), but I still can't figure out some things: 1) I've integrated Guice with Tomcat, and I've set up some bindings in a ServletModule: bind(MyServlet.class).asEagerSingleton(); serve("myUrl").with(MyServlet.class); serve("myOtherUrl").with(MyOtherServlet.class); (where MyOtherServlet class has a @Singleton annotation

F#: how to evaluate a “seq” to get all its values eagerly?

由 淺唱寂寞╮ 提交于 2019-12-08 17:35:58
问题 We know that in F#, seq is lazy evaluated. My question is, if I have a seq with limited number of values, how to convert it into some data type that contains all its value evaluated? > seq { for i in 1 .. 10 do yield i * i };; val it : seq<int> = seq [1; 4; 9; 16; ...] Thanks a lot. 回答1: The answer from @Carsten is correct: you can use Seq.toArray or Seq.toList if you wish to convert lazily evaluated sequences to lists or arrays. Don't use these function to force evaluation, though. The most

Lazy vs eager evaluation and double linked list building

由 狂风中的少年 提交于 2019-12-06 22:38:47
问题 I can't sleep! :) I've written small program building double linked list in Haskell. The basic language's property to make it was lazy evaluation (see the bunch of code below). And my question is can I do the same in a pure functional language with eager evaluation or not? In any case, what properties eager functional language must have to be able to build such structure (impurity?)? import Data.List data DLList a = DLNull | DLNode { prev :: DLList a , x :: a , next :: DLList a } deriving

hibernate关联关系延时加载异常

最近在学习hibernate，记录一些初学者可能会碰到的问题及解决方案。 下面是我在注解配置了多对一关系（多个用户对应一个组织）后，查询用户列表时返回的报错页面。 原来注解 @ManyToOne() 中的参数 fetch 的默认值是 FetchType.LAZY ，就是默认延时加载关联属性，但是延时后session已关闭，所以会报错。 解决办法是将 fetch 设置为 FetchType.EAGER（ EAGER ： adj.渴望的; 热切的，热情洋溢的; 热心的; 急切; ），解决。 Struts Problem Report Struts Problem Report Struts has detected an unhandled exception: Messages : could not initialize proxy - no Session java.lang.reflect.InvocationTargetException org.apache.struts2.json.JSONException: java.lang.reflect.InvocationTargetException File : org/hibernate/proxy/AbstractLazyInitializer.java Line number : 165 Stacktraces

Ways to avoid eager spool operations on SQL Server

问题 I have an ETL process that involves a stored procedure that makes heavy use of SELECT INTO statements (minimally logged and therefore faster as they generate less log traffic). Of the batch of work that takes place in one particular stored the stored procedure several of the most expensive operations are eager spools that appear to just buffer the query results and then copy them into the table just being made. The MSDN documentation on eager spools is quite sparse. Does anyone have a deeper
