如何在笔记本电脑的云端硬盘中读取文件夹中的文件 [英] How to read files inside a folder in Drive inside a notebook

问题描述

我想从Google Colab Notbook内的驱动器读取数据集. 我怎样才能做到这一点? 我做了这样的事情，但是没有用.

I want to read the dataset from drive inside Google Colab Notbook. how can I do that? I did something like this but it's not working.

train_data_dir = "data/train/"
validation_data_dir = "data/validation/"

数据文件夹如下:

data/
    train/
        dogs/
            dog001.jpg
            dog002.jpg
            ...
        cats/
            cat001.jpg
            cat002.jpg
            ...
    validation/
        dogs/
            dog001.jpg
            dog002.jpg
            ...
        cats/
            cat001.jpg
            cat002.jpg
            ...

推荐答案

我找到了使用驱动器FUSE包装器

您必须先安装驱动器保险丝包装，然后创建一个目录，然后将其安装，该目录是驱动器的根目录，将您的数据集上传到您的google驱动器，然后使用"/content/name_of_your_directory/dataset_name/"

you have to install the drive fuse wrapper then make a directory then mount it, that directory is the root directory of your drive, upload your dataset to your google drive and access it using "/content/name_of_your_directory/dataset_name/"

就我而言，我按照以下步骤操作:

in my case I followed these steps:

!apt-get update -qq 2>&1 > /dev/null
!apt-get install -y -qq software-properties-common python-software-properties module-init-tools
!add-apt-repository -y ppa:alessandro-strada/ppa 2>&1 > /dev/null
!apt-get update -qq 2>&1 > /dev/null
!apt-get -y install -qq google-drive-ocamlfuse fuse

然后

from google.colab import auth
auth.authenticate_user()

3-为Drive FUSE库生成凭据.

from oauth2client.client import GoogleCredentials
creds = GoogleCredentials.get_application_default()
import getpass

4-在Jupyter中解决STREAM和STDIN的顺序错误.

prompt = !google-drive-ocamlfuse -headless -id={creds.client_id} -secret={creds.client_secret} < /dev/null 2>&1 | grep URL
vcode = getpass.getpass(prompt[0] + '\n\nEnter verification code: ')
!echo {vcode} | google-drive-ocamlfuse -headless -id={creds.client_id} -secret={creds.client_secret}

5-创建目录并使用该目录挂载Google云端硬盘.

!mkdir -p yourdirectory
!google-drive-ocamlfuse yourdirectory

6-从类似于我的情况下的代码访问此目录

train_data_dir = "/content/yourdirectory/data/train/"
validation_data_dir = "/content/yourdirectory/data/validation/"
