通过google colab使用Mega.nz模块的问题

Question

当我像这样使用大量代码时，我会遇到这样的错误：

def uplaod_mega_nz(root,cloude='google_drive',title1=''):
 if (cloude=='mega'):

   mega = Mega()
   email = '????'
   password = 'password'
   m = mega.login(email, password)
   # login using a temporary anonymous account
   m = mega.login()
   quota = m.get_quota()
   # specify unit output kilo, mega, gig, else bytes will output
   space = m.get_storage_space(kilo=True)
   m.create_folder('yolo_car_database/'+title1+'/')
   folder = m.find('yolo_car_database/'+title1+'/')
   # m.upload('myfile.doc', folder[0])
   for path, subdirs, files in os.walk( root):
      for name in files:
          m.upload(os.path.join(path, name), folder[0])
   # public_exported_web_link = m.export('myfile.doc')
   # public_exported_web_link = m.export('my_mega_folder/my_sub_folder_to_share')
 if (cloude=='google_drive'):
     run_command('mkdir '+root+'/')
     copy_tree(root,'/content/gdrive/My Drive/yolo_car_database/' + title1 + '/')

错误如下：

谢谢。

Answer 1

这可以通过运行第一个块代码来完成，如下所示：

# @markdown <center><h3>Input Your Mega ID</h3></center><br>
from functools import wraps
import errno
import os
import signal
import subprocess
import shlex


class TimeoutError(Exception):
    pass


def timeout(seconds=10, error_message=os.strerror(errno.ETIME)):
    def decorator(func):
        def _handle_timeout(signum, frame):
            raise TimeoutError(error_message)

        def wrapper(*args, **kwargs):
            signal.signal(signal.SIGALRM, _handle_timeout)
            signal.alarm(seconds)
            try:
                result = func(*args, **kwargs)
            finally:
                signal.alarm(0)
            return result

        return wraps(func)(wrapper)

    return decorator


if not os.path.exists("/root/.ipython/ocr.py"):
    from subprocess import run
    from shlex import split

    shellCmd = "wget -qq https://raw.githubusercontent.com/biplobsd/OneClickRun/master/res/ocr.py \
                    -O /root/.ipython/ocr.py"
    run(split(shellCmd))
from ocr import runSh

@timeout(10)
def runShT(args):
    return runSh(args, output=True)


# MEGAcmd installing
if not os.path.exists("/usr/bin/mega-cmd"):
    print("Installing MEGA ...")
    runSh('sudo apt-get -y update')
    runSh('sudo apt-get -y install libmms0 libc-ares2 libc6 libcrypto++6 libgcc1 libmediainfo0v5 libpcre3 libpcrecpp0v5 libssl1.1 libstdc++6 libzen0v5 zlib1g apt-transport-https')
    runSh('sudo curl -sL -o /var/cache/apt/archives/MEGAcmd.deb https://mega.nz/linux/MEGAsync/Debian_9.0/amd64/megacmd-Debian_9.0_amd64.deb', output=True)
    runSh('sudo dpkg -i /var/cache/apt/archives/MEGAcmd.deb', output=True)
    print("MEGA is installed.")
else:
    !pkill mega-cmd

# INPUT YOUR MEGA ID

USERNAME = 'kayeyoc231@llubed.com'  # @param {type:"string"}
PASSWORD = "ss123456"  # @param {type:"string"}
if not (USERNAME == "" or PASSWORD == ""):
    try:
        runShT(f"mega-login {USERNAME} {PASSWORD}")
    except TimeoutError:
        runSh('mega-whoami', output=True)
else:
    print("Please Input your Mega IDs.")
# @markdown *After signing in, use the above cell(Main Cell) to transfer files from Mega to GDrive using the transfer quota of your Mega Pro Account*

然后通过挂载google Drive帐户，如下所示：

from google.colab import drive
drive.mount('/content/gdrive')
!mkdir "/content/gdrive/My Drive/yolo_car_database/"

# !cp /content "gdrive/My Drive/yolo_car_databe"

挂载后，您可以进入google dive文件夹，如下所示：

%cd /content/gdrive/MyDrive/

通过colab代码块销毁此代码：

!mega-cmd 

并将此代码写入其输入终端

sync <Source_path_folder_address> <mega_ns_destination_folder>

例如，ti可以是：

sync /content/gdrive/MyDrive/ .

然后，您可以编写ls命令来查看文件夹是否已同步到mega.nz驱动器。

所有这些都可以在here上看到。

此外，您还可以通过此链接查看mega-cmd帮助：

https://github.com/meganz/MEGAcmd

此外，您还可以在运行此答案第一部分编写的代码块后使用此命令：

from ocr import runSh
 
 
root = <the Colab target folder to be copied to mega.nz drive>
runSh('mega-cd /' )
runSh('mega-mkdir SomeThing ')
runSh( mega-ls ')
runSh('mega-cd SomeThing ')
 
runSh('mega-put '+ root+' . ')
runSh(' mega-ls')
