import smtplib 
EMAIL = 'email@email.com'
PASS_EMAIL = '**********'
email = "another@email.com"
smtpObj = smtplib.SMTP('smtp.gmail.com', 587)
smtpObj.starttls()
smtpObj.login(EMAIL, PASS_EMAIL)
smtpObj.sendmail(EMAIL, email, "Hello, a message for testing!")
smtpObj.quit()

如果我通过 gmail 发送邮件，那么一切正常。随着时间的推移，Yandex。mail.ru 和 rambler 不起作用 - 邮件无法到达。也就是说，如果我尝试通过 gmail 向其他邮件服务发送一封信，那么它不会到达他们（即使是垃圾邮件）。怎么修？

如您所见，该模块re不支持\p（匹配某些 Unicode 属性，用于在 RE 中方便地使用 Unicode）。

    def makeCode(self):

        cursor = self.textCursor()

该功能makeBold使所选文本变为粗体，为所选文本makeBG添加背景等。

现在问题：

  • 怎么做双下划线？
  • 如何制作下划线ala：

我永远不会知道，QTextCharFormat没有这样的对象。(

有一个具有以下结构的包：

在此处输入图像描述

这个项目最初是用 python 2 编写的，我正在将它移植到 python 3。走过它：

2to3 -w *.py && rm *.bak

重新设计了一些更微妙的东西（比如重命名为 itertools）。现在发生错误（导入时）：

ImportError: attempted relative import with no known parent package

如何进行永久调用以接受更新 QTextEdit 小部件？

只是线程不起作用：

        self.initUI()

    def initUI(self):
        self.id = 'default'
        self.idl = QLineEdit()
        self.lay.addWidget(self.idl)

        self.log = QPushButton()
        self.log.setText('Connect')
        self.log.clicked.connect(self.setId)
        self.lay.addWidget(self.log)

        self.board = QTextEdit()
        self.board.textChanged.connect(self.send)
        self.board.setMinimumSize(1200, 700,)
        self.board.setStyleSheet('font-size:20px;')
        self.lay.addWidget(self.board)
        thread = Thread(target=self.accept)
        thread.start()
    def setId(self):
        self.id = self.idl.text()

    def send(self):
        requests.get(f'http://localhost:8080/set/{self.id}/{self.board.toPlainText()}/...')

    def accept(self):
        self.board.setText(requests.get(f'http://localhost:8080/get/{self.id}/...').text)


if __name__ == '__main__':

如果您按照上述方式进行操作，则会发生错误：

我正在为 Pascal 编写一个微型 IDE。这是一段非常简化的代码：

class MainWindow(QMainWindow):
    def __init__(self):
        super(MainWindow, self).__init__()

        wid = QWidget()
        self.lay = QVBoxLayout()
        wid.setLayout(self.lay)
        self.setCentralWidget(wid)

        self.initUI()

    def initUI(self):

        self.inp = QTextEdit()
        self.out = QTextEdit()
        self.out.setReadOnly(True)

        self.lay.addWidget(self.inp)
        self.lay.addWidget(self.out)
   ...
   ...
       def run(self):
        try:
            with open('cached/run.pas', 'w') as f:
                f.write(self.inp.toPlainText())

            config = cfg .ConfigParser()
            config.read('settings.ini')
            compiler = config.get('settings-n-preference', 'engine')

            compiling_logs = os.popen(compiler + ' cached/run.pas').read()
            self.out.setText(os.popen('cached/run').read())

            os.remove('cached/run.pas')
            os.remove('cached/run')


        except:
            self.out.setText(compiling_logs)

如果 Pascal 程序不需要输入，则一切正常。好吧，例如：

program Hello;
begin
  writeln ('Hello, world.');
end.

好吧，如果这已经是类似的东西（也就是说，你需要输入一些东西），那么便笺响应程序：

program Hello;
begin
  writeln ('Hello, world.');
  readln;
end.

怎样成为？

假设我这样训练模型：

filename = 'model.h5'
checkpoint = ModelCheckpoint(filename, monitor='val_loss', verbose=1, save_best_only=True, mode='min')
model.fit(trainX, trainY, epochs = 100, batch_size=256, validation_data=(testX, testY), callbacks=[checkpoint])

它保存在 model.h5 中。

我怎样才能重新开始训练她，但保留上次的进度？

也就是说，要：

model.fit(trainX, trainY, epochs = 100, batch_size=256, validation_data=(testX, testY), callbacks=[checkpoint])

再次： 

model.fit(trainX, trainY, epochs = 100, batch_size=256, validation_data=(testX, testY), callbacks=[checkpoint]

相当于：

model.fit(trainX, trainY, epochs = 200, batch_size=256, validation_data=(testX, testY), callbacks=[checkpoint]

我正在尝试从文本中制作一个语料库。问题是文本非常大，我遇到了一个异常：

ValueError: [E088] Text of length 1027203 exceeds maximum of 1000000. The v2.x parser and NER models require roughly 1GB of temporary memory per 100,000 characters in the input. This means long texts may cause memory allocation errors. If you're not using the parser or NER, it's probably safe to increase the `nlp.max_length` limit. The limit is in number of characters, so you can check whether your inputs are too long by checking `len(text)`.

升级安全nlp.max_length吗？这是代码：

import spacy
nlp = spacy.load('fr_core_news_md')
f = open("text.txt")
doc = nlp(''.join(ch for ch in f.read() if ch.isalnum() or ch == " "))
f.close()
del f
words = []
for token in doc:
    if token.lemma_ not in words:
        words.append(token.lemma_)

f = open("corpus.txt", 'w')
f.write("Number of words:" + str(len(words)) + "\n" + ''.join([i + "\n" for i in sorted(words)]))
f.close()

更新

当我尝试这样做时，我仍然得到同样的错误：

import spacy
nlp = spacy.load('fr_core_news_md')
nlp.max_length = 1027203
f = open("text.txt")
doc = nlp(''.join(ch for ch in f.read() if ch.isalnum() or ch == " "))
f.close()
del f
words = []
for token in doc:
    if token.lemma_ not in words:
        words.append(token.lemma_)
