是否有可能将图像嵌入gorilla-repl的markdown单元格中？

我想将图像保存在项目src根目录中的文件夹中,leiningen并能够将图像嵌入到我的工作表中:

![plot 1](img/plot_1.png)

我正在尝试编组包含ISO格式的时间戳的响应,如下所示:

{
...
    "time" : "2014-07-02T04:00:00.000000Z"
...
}

进入ZonedDateTime我的域模型对象中的字段.最终,如果我使用在以下片段中注释的解决方案,它会起作用.在SO上有许多类似的问题,但我想得到一个具体的答案,另一种使用的方法JacksonJsonProvider有ObjectMapper + JavaTimeModule什么问题？

        ObjectMapper mapper = new ObjectMapper();
        mapper.registerModule(new JavaTimeModule());
        JacksonJsonProvider provider = new JacksonJsonProvider(mapper);
        Client client = ClientBuilder.newBuilder()
//                .register(new ObjectMapperContextResolver(){
//                    @Override
//                    public ObjectMapper getContext(Class<?> type) {
//                        ObjectMapper mapper = new ObjectMapper();
//                        mapper.registerModule(new JavaTimeModule());
//                        return mapper;
//                    }
//                })
                .register(provider)
                .register(JacksonFeature.class)
                .build();

我得到的错误:

javax.ws.rs.client.ResponseProcessingException: com.fasterxml.jackson.databind.JsonMappingException: Can not construct instance of java.time.ZonedDateTime: no String-argument constructor/factory method to deserialize from String …

我得到了一个最小的回声状态网络(ESN)的例子,我在试图理解回声状态网络时进行了分析.不幸的是,我有一些问题,理解为什么这真的有效 这一切都分解为问题:

• [什么定义| 什么是ESN 的回声状态？
• 是什么让ESN如此简单快速地学习如Mackey-Glass功能这样复杂的非线性函数？

这里首先是一段显示初始化重要部分的代码:

% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%
% Generate the ESN reservoir
% 
% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

rand('seed', 42);

trainLen = 2000;
testLen  = 2000;
initLen  = 100;
data     = load('MackeyGlass_t17.txt');

%         Input neurons
inSize  = 1; 
%         Output neurons 
outSize = 1;
%         Reservoir size
resSize = 1000;
%         Leaking rate
a       = 0.3; 
%         Input weights
Win     = ( rand(resSize, (inSize+1) ) - 0.5) .* 1;
%         Reservoir weights
W       = …

我设置了一个多模块maven项目,它由一个用于构建nar jni库的模块和一个依赖于该库的jar打包模块组成.

我能够将nar库安装到我的本地maven存储库,但是我无法在依赖模块中使用它.

例如,我跑mvn nar:nar-unpack,我得到:

[INFO] ------------------------------------------------------------------------
[INFO] Building nar-dependent 1.0-SNAPSHOT
[INFO] ------------------------------------------------------------------------

[INFO] Unpacking 0 dependencies to /home/przemek/Documents/stimulant/nar-dependent/target/nar
[INFO] ------------------------------------------------------------------------

似乎没有nar依赖,这显然不正确.此外,尝试执行使用jni库的类的main方法失败:

mvn exec:java -Dexec.mainClass=App

我想把这个java代码翻译成Frege Haskell:

    PApplet pApplet = new PApplet();
    System.out.print(pApplet.toString());
    PApplet.runSketch(new String[]{"test"}, pApplet);

我到目前为止做了:

data PApplet = mutable native processing.core.PApplet
  where
    native new :: () -> IO PApplet
    native toString :: PApplet -> IO String

native runSketch processing.core.PApplet.runSketch
  :: ArrayOf RealWorld String -> PApplet -> IO ()

main _ = do p <- PApplet.new
            pStr <- p.toString
            putStrLn pStr
            args = JArray.fromList ["test"]
            runSketch args p

部分main编译然后我得到那些错误:

E Process.fr:14: type error in expression fromList ("test":[])
    type is : STMutable t1 …

该定义适用于ghci:

recip :: Fractional a ? a ? a
recip n = 1 / n

尝试一下frege-repl我得到了:

E <console>.fr:6: can't resolve `Fractional`, did you mean `Exceptional`
    perhaps?

"Hoogling" Fractional没有给我什么.
