在 google colab 中访问目录

Question

good evening guys, i am using google colab, because it supports GPU and TPU and without it, i can't run many Deep Learning codes on my computer, i have installed already google colab ,just question is following: let us suppose my working directory is this https://drive.google.com/drive/u/0/folders/1EvNegzEhMp0NtKXY_Hm9jsBpA4Amwcs

here i can upload images, csv files and so on, i have searched a lot of material about this one and i found following

from google.colab import drive
 drive.mount('/content/drive')

i have run this code and follow instructions and finally i got : Mounted at /content/drive

after that i have uploaded simple file to this directory and run following code

from google.colab import drive
drive.mount('/content/drive')
import matplotlib.pyplot as plt
import numpy as np
import cv2
import skimage
from skimage import data
from skimage import io
Image =cv2.imread('palm.jpg')
io.imshow(Image)

AttributeError: 'NoneType' object has no attribute 'dtype' , i have searched documentation about this error and found, that my Image might be [] , so what is reason of an error? please help me

Answer 1

Mention full path of image in code '/content/drive/MyDrive/Machine Learning/OpenCV/palm.jpg'

from google.colab import drive
drive.mount('/content/drive')
import matplotlib.pyplot as plt
import numpy as np
import cv2
import skimage
from skimage import data
from skimage import io
Image =cv2.imread('/content/drive/MyDrive/Machine Learning/OpenCV/palm.jpg')
io.imshow(Image)

Answer 2

When you mount your drive, look for the "drive" folder in your contents. You have to find the path to the image from that folder. It may be something like img_path = '/content/drive/My Drive/sample.jpg' .
