UnicodeDecodeError с matplotlib.animation в Python 3

0 голосов
/ 23 января 2020

Этот код хорошо работает с Python 2.7.17 (python test.py), но выдает кучу сообщений об ошибках с Python 3.6.9 (python3 test.py).

Что не так с code?

Я видел несколько похожих вопросов, включая UnicodeDecodeError, но не могу это исправить.

Я нахожусь на рабочем столе Ubuntu 18.04.3.


Мой код: 

import cv2
import matplotlib.pyplot as plt
import matplotlib.animation as animation

imgarr = []
imgarr.append(cv2.imread('../../img/circle-1.png', cv2.IMREAD_GRAYSCALE))
imgarr.append(cv2.imread('../../img/circle-2.png', cv2.IMREAD_GRAYSCALE))

fig = plt.figure("ArtistAnimation")

img = []

for i in range(2):
    img.append([plt.imshow(imgarr[i], cmap='gray')])

ani = animation.ArtistAnimation(fig,
                                img,
                                interval=250,
                                blit=True,
                                repeat_delay=0)

plt.show()
