本文介绍了Google Colab无法访问驱动器内容的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
即使我将我的Google Drive(及其中的数据集)定义为google colab,但是当我运行我的代码时,也会出现此错误:FileNotFoundError:[Errno 2]没有这样的文件或目录:'content/drive/My Drive /....
Even though I defined my Google Drive(and my dataset in it) to google colab but when I run my code I give this error:FileNotFoundError: [Errno 2] No such file or directory: 'content/drive/My Drive/....
我已经在google colab中定义了google驱动器,我可以通过google colab访问它,但是当我运行代码时,我会提示此错误
I already defined google drive in google colab and I can access to it through google colab but when I run my code I give this error

print(prediction)
推荐答案
安装后,移至数据集文件夹.
After mounting, move into the dataset folder.
cd content/drive/My Drive/Convolutional_Neural_Networks/dataset/
请勿使用!.
然后将目录设置为./training_set
Don't use the !.
Then set your directory as ./training_set
