所以我试图通过做一点多处理来加快我的计算时间

我正在尝试使用池工人.

在我的代码的顶部,我有

import Singal as s
import multiprocessing as mp
def wrapper(Channel):
    Noise_Frequincies = []
    for i in range(1,125):
        Noise_Frequincies.append(60.0*float(i))
    Noise_Frequincies.append(180.0)
    filter1 = s.Noise_Reduction(Sample_Rate,Noise_Frequincies,Channel)
    return filter1

然后到时候我用

Both_Channels = [Chan1, Chan2]
results = mp.Pool(2).map(wrapper,Both_Channels)
filter1 = results[0]
filter2 = results[1]

我收到以下错误

Exception in thread Thread-2:
Traceback (most recent call last):
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/threading.py", line 808, in __bootstrap_inner

put(task)
PicklingError: Can't pickle <type 'function'>: attribute lookup …

所以我正在尝试对一个块进行单元测试

我的测试很简单

test("When loading patients, bloc should emmit [Loading], [OwnersLoaded]", (){
      //arrange
      var owners = [Owner(id: "TestId")];
      when (mockPatientsRepository.getOwnersForCurrentPractice()).thenAnswer((_)=>Future.value(owners));
      final List<PatientsState> expected = [patientsBloc.initialState, Loading(), OwnersLoaded(owners)];

      //assert later
      expectLater(patientsBloc, emitsInOrder(expected));

      //act
      useCase.getPatients();
    }); 

所有者确实覆盖了等于和哈希

我的错误信息

Expected: should do the following in order:
          • emit an event that <Instance of 'InitialPatientsState'>
          • emit an event that <Instance of 'Loading'>
          • emit an event that <Instance of 'OwnersLoaded'>
  Actual: <Instance of 'PatientsBloc'>
   Which: emitted • Instance of 'InitialPatientsState'
                  • Instance of 'Loading' …

我似乎无法让反应根 div 来填充浏览器页面。

我已经尝试添加以下 CSS，以及几乎所有的组合

html, body {
    margin: 0;
    height: 100%;
}
.fill-height {
    min-height: 100%;
    height:auto !important; /* cross-browser */
    height: 100%; /* cross-browser */
}

#root > [data-reactroot] { height: 100vh }

所以我正在为网络应用程序创建一个颤振。有点冒险，但我真的只想要一个初始原型，希望当我需要准备好生产时，它至少处于测试阶段。

无论如何，我正在尝试创建一个登录页面，但实际上无法在 TextFiled 中输入任何内容。

我尝试添加/删除 TextEditingController 和输入装饰。我也尝试过 TextField 和 TextFormField

Widget loginWidget() {
    return Container(
      width: 650,
      child: Card(
        margin: EdgeInsets.all(5.0),
        color: UiColors.CardBlue,
        child: Column(
          mainAxisSize: MainAxisSize.min,
          crossAxisAlignment: CrossAxisAlignment.center,
          children: <Widget>[
            Row(
              mainAxisSize: MainAxisSize.min,
              children: <Widget>[
                MaterialButton(
                  minWidth: 300,
                  color: UiColors.CardBlue,
                  child: Text("Login", style: TextStyle(color: Colors.white),),
                  onPressed: (){}, // do nothing, this is already the login
                ),
                MaterialButton(
                  minWidth: 300,
                  elevation: 10,
                  color: UiColors.ButtonBlue,
                  child: Text("Register", style: TextStyle(color: Colors.white),),
                  onPressed: toggleLogin,
                )
              ],
            ),
            TextField(
              controller: usernameController,
              decoration: InputDecoration(
                border: …

我正在尝试使用多处理来处理我的内存问题，但是我无法获取要腌制的函数，而且我不知道为什么。我的主要代码开始于

def main():
    print "starting main"
    q = Queue()
    p = Process(target=file_unpacking,args=("hellow world",q))
    p.start()
    p.join()
    if p.is_alive():
        p.terminate()
    print "The results are in"
    Chan1 = q.get()
    Chan2 = q.get()
    Start_Header = q.get()
    Date = q.get()
    Time = q.get()
    return Chan1, Chan2, Start_Header, Date, Time

def file_unpacking(args, q):
    print "starting unpacking"
    fileName1 = "050913-00012"
    unpacker = UnpackingClass()
    for fileNumber in range(0,44):
        fileName = fileName1 + str(fileNumber) + fileName3
        header, data1, data2 = UnpackingClass.unpackFile(path,fileName)

        if header == None:
            logging.warning("curropted file found at …
