Colaboratory から、大きなサイズのファイルを、PyDrive を使って Google ドライブにアップロードしようとすると、RedirectMissingLocation 例外が発生して失敗する。
回避方法はこちら。
問題の詳細
サンプルコードは以下のリンクを参照。
外部データ: ローカル ファイル、ドライブ、スプレッドシート、Cloud Storage - Colaboratory
> Google ドライブ > PyDrive
from pydrive.auth import GoogleAuth
from pydrive.drive import GoogleDrive
from google.colab import auth
from oauth2client.client import GoogleCredentials
auth.authenticate_user()
gauth = GoogleAuth()
gauth.credentials = GoogleCredentials.get_application_default()
drive = GoogleDrive(gauth)
なお、投稿時点（2021.7.17）でインストールされていた PyDrive のバージョンは 1.3.1（詳細）。
Colaboratory 上にあるファイルを Google ドライブにアップロードするには、次のようにする。
dfile = drive.CreateFile()
dfile.SetContentFile("path.to.large.file")
dfile.Upload()
ここで path.to.large.file のファイルサイズが大きいと、RedirectMissingLocation 例外が発生して失敗する（詳細）。
RedirectMissingLocation: Redirected but the response is missing a Location: header.
原因と回避方法
原因は PyDrive が依存している httplib2 のバグのようである。
詳細は以下の issue を参照。
httplib2 v0.16.0 breaks the library · Issue #803 · googleapis/google-api-python-client · GitHub
この issue に書かれているように、httplib2 をダウングレードすることで回避できる可能性がある。
なお、投稿時点でインストールされていた httplib2 のバージョンは 0.17.4（詳細）。
pip install -U httplib2==0.15.0
ダウングレードが終わったら、ランタイムを再起動すること。
