keras - Google Colab 无法访问驱动器内容

Question

即使我将我的 Google 云端硬盘(以及其中的数据集)定义为 google colab，但是当我运行我的代码时，我给出了这个错误:FileNotFoundError: [Errno 2] No such file or directory: 'content/drive/My Drive/....

我已经在 google colab 中定义了 google drive 并且我可以通过 google colab 访问它但是当我运行我的代码时我给出了这个错误

挂载后，进入数据集文件夹。

cd content/drive/My Drive/Convolutional_Neural_Networks/dataset/

不要使用!。然后将您的目录设置为 ./training_set
