在 Cloud Shell 中运行Google 的 Slaven Bilac 发布的示例代码时，会发生错误。

# Takes about 30 mins to preprocess everything.  We serialize the two

如何修改来自GoogleCloudPlatform/cloudml-samples/flowers的文件以避免这种情况？

查克，

您看到的问题似乎是由于版本不匹配造成的。简单的解决方法是用 preprocess.py 中 default_values dic 中的 temp_location 替换 staging_location：

default_values = {
    'project':
        get_cloud_project(),
    # **here**  
    'temp_location':
        os.path.join(os.path.dirname(parsed_args.output_path), 'temp'),
    'runner':
        'DataflowRunner',
    'extra_package':
        Default.CML_PACKAGE,
    'save_main_session':
        True,
}

我们将很快更新示例以反映这一点。

您是否尝试过运行CloudShell 设置脚本？它有助于管理一些版本，这似乎是这里的核心问题：

curl https://raw.githubusercontent.com/GoogleCloudPlatform/cloudml-samples/master/tools/setup_cloud_shell.sh | bash
