Question

我已按照大多数教程中介绍的有关如何将自定义数据集上传到google colab的所有步骤进行操作。但是我遇到了一个错误，尝试了很多错误但还是无法解决。

我正在尝试使用自定义数据集训练CNN模型。我尝试使用大多数教程中给出的代码段将其上传到colab。

运行代码段时显示以下错误

#this is the code snippet I have taken from tutorials to upload dataset to google colab.
    !pip install -U -q PyDrive

    # Insert your file ID
    # Get it by generating a share URL for the file
    # An example : https://drive.google.com/file/d/1iz5JmTB4YcBvO7amj3Sy2_scSeAsN4gd/view?usp=sharing
    zip_id = 'https://drive.google.com/open?id=1RqLx88tx2FCV0Z3CHsqVtx7S3_ffE-UW'

    from pydrive.auth import GoogleAuth
    from pydrive.drive import GoogleDrive
    from google.colab import auth
    from oauth2client.client import GoogleCredentials
    import zipfile, os

    # 1. Authenticate and create the PyDrive client.
    auth.authenticate_user()
    gauth = GoogleAuth()
    gauth.credentials = GoogleCredentials.get_application_default()
    drive = GoogleDrive(gauth)

    if not os.path.exists('MODEL'):
        os.makedirs('MODEL')

    # 2. Download Zip
    print ("Downloading zip file")
    myzip = drive.CreateFile({'id': zip_id})
    myzip.GetContentFile('model.zip')

    # 3. Unzip
    print ("Uncompressing zip file")
    zip_ref = zipfile.ZipFile('model.zip', 'r')
    zip_ref.extractall('MODEL/')
    zip_ref.close()

OMG。经过一个小时（几乎8个小时）的互联网研究和头脑风暴，我找到了答案。如果有任何新手在colab上工作并遇到类似错误，这就是我如何解决此错误。上面代码的问题是我们分配文件ID的方式。 zip_id ='https://drive.google.com/open?id=1RqLx88tx2FCV0Z3CHsqVtx7S3_ffE-UW'。我见过的大多数教程都告诉我们，只需右键单击google驱动器中的文件并复制共享链接地址即可获取文件ID。但是文件ID并不是我们复制的全部内容。文件ID仅在id =之后（在本例中为1RqLx88tx2FCV0Z3CHsqVtx7S3_ffE-UW）。将其指定为ID后，错误消失了。希望此回复对其他合作者有所帮助。
