我需要一个包的所有功能的列表，包括未导出的功能，我对single不走运：

import numpy as np
import logging
import sys
import time
import itertools
import timeit


logging.basicConfig(stream=sys.stdout,
                    level=logging.DEBUG,
                    format='%(message)s')


def run():
    series = 2
    resolutions = 2
    buffer_len = 3
    symbols = range(50)

    #mat = np.random.choice(symbols, size=(series, resolutions, buffer_len))

    mat = np.array([
            [[0, 0, 1],  # series 0, resolution 0
             [1, 3, 2]],  # series 0, resolution 1
            [[2, 1, 2],  # series 1, resolution 0
             [3, 3, 3]],  # series 1, resoltuion 1
            # [[4, 5, 6, 10],
            #  [7, 8, 9, 11]],
        ])

    start = time.time()
    index_mat = np.indices((series, resolutions, buffer_len))

    # This loop shifts all series but the one being looked at, and zips the
    # element being looked at with every other member of that row

    #cross_pairs = []
    right_shift_indices = [index_mat[0], index_mat[1], (index_mat[2] - 1) % buffer_len]

    for i in range(series):
        right_shift_indices[2][i] = (right_shift_indices[2][i] + 1) % buffer_len


        # create a new matrix from the modified indices
        mat_shifted = mat[right_shift_indices]
        mat_shifted_t = mat_shifted.T.reshape(-1, series)

        #cross_pairs[i,:,:,:-1] = (np.dstack((single.reshape(-1,1).repeat(series-1,1), mat_shifted_t))).reshape(resolutions, buffer_len, (series-1), 2, order='F')

        right_shift_indices[2][i] = (right_shift_indices[2][i] - 1) % buffer_len
        #cross_pairs.extend([zip(itertools.repeat(x[i]), np.append(x[:i], x[i+1:])) for x in mat_shifted_t])

    circular_in_series_zips = np.stack([mat[:, :, -1], mat[:, :, 0]], axis=2)
    # This creates the final array.
    # Index 0 is the preceding series
    # Index 1 is the resolution
    # Index 2 is the location in the buffer
    # Index 3 is for the first n-1 elements, the following series, and for the last element
    #         it's the next element of the Index 0 series
    # Index 4 is the index into the two element pair
    cross_pairs[:,:,:-1,-1] = in_series_zips

我们可以在import javafx.application.Application; import javafx.collections.FXCollections; import javafx.collections.ObservableList; import javafx.embed.swing.SwingFXUtils; import javafx.scene.Scene; import javafx.scene.image.WritableImage; import javafx.stage.Stage; import javafx.scene.chart.*; import javafx.scene.Group; import java.io.File; import java.io.IOException; import java.nio.file.Path; import java.nio.file.Paths; import javax.imageio.ImageIO; public class Test extends Application { @Override public void start(Stage stage) { Scene scene = new Scene(new Group()); stage.setTitle("Imported Fruits"); stage.setWidth(500); stage.setHeight(500); ObservableList<PieChart.Data> pieChartData = FXCollections.observableArrayList( new PieChart.Data("Grapefruit", 13), new PieChart.Data("Oranges", 25), new PieChart.Data("Plums", 10), new PieChart.Data("Pears", 22), new PieChart.Data("Apples", 30)); final PieChart chart = new PieChart(pieChartData); chart.setTitle("Imported Fruits"); ((Group) scene.getRoot()).getChildren().add(chart); stage.setScene(scene); WritableImage img = new WritableImage(800, 800); scene.snapshot(img); writeImage(Paths.get("/Users/images"), "test.png", img); } public static void writeImage(Path path, String fileName, WritableImage image) { File file = new File(Paths.get(path.toString(), fileName).toString()); try { ImageIO.write(SwingFXUtils.fromFXImage(image, null), "png", file); } catch (IOException e) { e.printStackTrace(); } } public static void main(String[] args) { launch(args); } }中使用getNamespace返回所有未导出的函数
