关于机器学习:Anaconda-jupyter-notebook路径读取错误提示路径不存在解决方案

当我在 jupyter notebook 里想展现一张图片时，我应用了以下代码：

import matplotlib.pyplot as plt
import skimage.io as io
 
path = "E:\pythonFiles\YOLOX\YOLOX_outputs\yolox_l\vis_res\2022_06_06_16_26_36\dog.jpg"
image = io.imread(path)
plt.imshow(image)

而后 jupyter notebook 给出了报错：

FileNotFoundError: No such file: 'E:\pythonFiles\YOLOX\YOLOX_outputs\yolox_l is_res 2_06_06_16_26_36\dog.jpg'

独自看报错的最初一行：

FileNotFoundError: No such file: 'E:\pythonFiles\YOLOX\YOLOX_outputs\yolox_l is_res 2_06_06_16_26_36\dog.jpg'

本次报错最重要的是最初一行，这其实是在阐明，零碎读取到的门路与咱们本人输出的门路并不一样，所以才没有读取到相应的文件，那么为什么不一样呢？我感觉大略是因为 \v ,\t,\s 这样的字眼自身有其非凡的意义，放在字符串里时变成了占位符，所以产生了这样的谬误。
解决办法也很简略，间接应用两个斜杠即可。
也就是说将原来的门路：

E:\pythonFiles\YOLOX\YOLOX_outputs\yolox_l\vis_res\2022_06_06_16_26_36\dog.jpg

改写成：

E:\pythonFiles\YOLOX\YOLOX_outputs\yolox_l\\vis_res\\2022_06_06_16_26_36\dog.jpg
