kaggle的output没办法直接下载文件夹,倒是可以下载文件,当你的训练模型很多个文件的时候, 一个一个下载太慢了, 所以先将output压缩一下,然后下载就行了

直接在cell中运行此代码即可

import os
import zipfile
import datetime

def file2zip(packagePath, zipPath):
    '''
  :param packagePath: 文件夹路径
  :param zipPath: 压缩包路径
  :return:
  '''
    zip = zipfile.ZipFile(zipPath, 'w', zipfile.ZIP_DEFLATED)
    for path, dirNames, fileNames in os.walk(packagePath):
        fpath = path.replace(packagePath, '')
        for name in fileNames:
            fullName = os.path.join(path, name)
            name = fpath + '\\' + name
            zip.write(fullName, name)
    zip.close()


if __name__ == "__main__":
    # 文件夹路径
    packagePath = '/kaggle/working/'
    zipPath = '/kaggle/working/output.zip'
    if os.path.exists(zipPath):
        os.remove(zipPath)
    file2zip(packagePath, zipPath)
    print("打包完成")
    print(datetime.datetime.utcnow())

下载即可

清空kaggle/working下指定文件夹 直接在cell中运行下面代码

import shutil
import os

if __name__ == '__main__':
    path = '/kaggle/working/model'
    if os.path.exists(path):
        shutil.rmtree(path)
        print('删除完成')
    else:
        print('原本为空')
