我正在Google Colab上的文件中工作,并使用以下代码:
import numpy as np
import matplotlib.pyplot as plt
import os
import cv2
DATADIR="/Users/boris/PetImages"
CATEGORIES= ["Dog","Cat"]
for category in CATEGORIES:
path = os.path.join(DATADIR, category)
for img in os.listdir(path):
img_array = cv2.imread(os.path.join(path,img), cv2.IMREAD_GRAYSCALE)
plt.imshow(img_array, cmap="gray")
plt.show()
break
break
我正在尝试在Mac上导入两个文件夹。但是,我继续收到以下错误:
---------------------------------------------------------------------------
FileNotFoundError Traceback (most recent call last)
<ipython-input-36-4ea265030377> in <module>()
9 for category in CATEGORIES:
10 path = os.path.join(DATADIR, category)
---> 11 for img in os.listdir(path):
12 img_array = cv2.imread(os.path.join(path,img), cv2.IMREAD_GRAYSCALE)
13 plt.imshow(img_array, cmap="gray")
FileNotFoundError: [Errno 2] No such file or directory: "/Users/boris/PetImages/Dog"

Google colab在无法访问本地文件系统的远程虚拟机上运行。要使用这些文件,您首先必须将它们上传到Colab机器。
有关在Colab中访问数据的各种方法的信息,请参见https://colab.research.google.com/notebooks/io.ipynb。
