Pychrm Community Edition calls matplotlib pyplot. Solution of imshow() function image not popping up

Preface

Learn from teacher Wu Enda's deeplearningai Course , Complete programming assignment 2 of the second week , I want to be here pycharm Rewrite the code in , It is found that the image does not display after loading the dataset .

Method 1 ：

Import pylab library (pylab yes matplotlib One of the modules in , Import directly .)
stay plt.imshow(train_set_x_orig[index]) Add a sentence after pylab.show()

import numpy as np
from matplotlib import pyplot as plt
import h5py
import scipy
from PIL import Image
from scipy import ndimage
import scipy.misc
import pylab


def load_dataset():
    train_dataset = h5py.File('datasets/train_catvnoncat.h5', "r")
    train_set_x_orig = np.array(train_dataset["train_set_x"][:])  # your train set features
    train_set_y_orig = np.array(train_dataset["train_set_y"][:])  # your train set labels

    test_dataset = h5py.File('datasets/test_catvnoncat.h5', "r")
    test_set_x_orig = np.array(test_dataset["test_set_x"][:])  # your test set features
    test_set_y_orig = np.array(test_dataset["test_set_y"][:])  # your test set labels

    classes = np.array(test_dataset["list_classes"][:])  # the list of classes

    train_set_y_orig = train_set_y_orig.reshape((1, train_set_y_orig.shape[0]))
    test_set_y_orig = test_set_y_orig.reshape((1, test_set_y_orig.shape[0]))

    return train_set_x_orig, train_set_y_orig, test_set_x_orig, test_set_y_orig, classes


train_set_x_orig, train_set_y, test_set_x_orig, test_set_y, classes = load_dataset()

index = 5
plt.imshow(train_set_x_orig[index])
pylab.show()
print("y = " + str(train_set_y[:, index]) + ", it's a '" + classes[np.squeeze(train_set_y[:, index])].decode(
    "utf-8") + "' picture.")

Method 2 ：

stay plt.imshow(train_set_x_orig[index]) Add a sentence after plt.show()

PS

1. The online solution is pycharm–>File | Settings | Tools | Python Scientific | Uncheck the Show plots in tool window, But mine pycharm There is no Python Scientific This option
2. pycharm Use plt Don't show picture solutions
   This blog explains why jupyter Can be displayed in and pycharm Cannot display .
3. I feel that the image source of China University of science and technology is very easy to use

pip3 install -i https://pypi.mirrors.ustc.edu.cn/simple/ pylab
