Я пытаюсь прочитать из журнала и графика некоторые данные о расстоянии от изображения, из которого они получены, например:
import time
import numpy as np
import re
import matplotlib.pyplot as plt
from scipy.spatial import distance
log_path = 'path/to/log/2018-10-31_log.txt'
log = open (log_path, "r")
lines = log.readlines()
i = 0
distances1 = []
distances2 = []
image_numbers = []
for line in lines:
image_name = (line.split()[2])
image_number = re.search('_image(.*).jpg',image_name)
distance1 = float(line.split()[5])
distance2 = float(line.split()[8])
distances1.append(distance1)
distances2.append(distance2)
image_numbers.append(image_number.group(1))
plt.plot([distance1],[image_numbers])
plt.show()
Однако при запуске кода я получаю следующую ошибку:
Traceback (most recent call last):

TypeError: unhashable type: 'numpy.ndarray'
списки distance1 и image_numbers действительно довольно велики и содержат более 16000 значений в каждом, но я не понимаю, как подойти к этой ошибке. Что мне здесь не хватает?
