JFrame frame = new JFrame("Testing");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.add(new TestPane());

public class TestPane extends JPanel {
public TestPane() {
setLayout(new GridBagLayout());
setBorder(new EmptyBorder(10, 10, 10, 10));
JTextField field = new JTextField(10);
((AbstractDocument)field.getDocument()).setDocumentFilter(new PropercaseDocumentFilter());
add(field);
}
}
public class PropercaseDocumentFilter extends DocumentFilter {
@Override
public void replace(FilterBypass fb, int offset, int length, String text, AttributeSet attrs) throws BadLocationException {

super.replace(fb, offset, length, text, attrs);
}
protected String modify(FilterBypass fb, int offset, String text, AttributeSet attrs) throws BadLocationException {
if (text.length() > 0) {
Document doc = fb.getDocument();
StringBuilder sb = new StringBuilder(text);
if (doc.getLength() == 0) {
sb.setCharAt(0, Character.toUpperCase(sb.charAt(0)));
} else if (offset > 0 && offset < doc.getLength()) {
if (doc.getText(offset - 1, 1).equals(" ")) {
sb.setCharAt(0, Character.toUpperCase(sb.charAt(0)));

和Python 2.7.14像这样对由cPickle到(LabelEncoder, NumPy array, NumPy array)组成的元组进行腌制：
le_arr1_arr2.pkl我使用pickle.dump((le, arr1, arr2), open("le_arr1_arr2.pkl", "wb"))
1.71版在ML Engine实例（Linux计算机）上进行此操作。
然后将其复制到笔记本电脑（mac）中，然后尝试：
cPickle
我再次使用le, arr1, arr2 = pickle.load(open("le_arr1_arr2.pkl", "rb")) 1.71版，我得到了：
cPickle知道这里发生了什么吗？我很困惑...
谢谢！
