从Google Colab下载文件时出现错误104

Question

试图下载保存为~100MB HDF5文件的keras模型文件.

from google.colab import files
files.download('models/mlp_mnist_l.h5')

但我一直得到以下ConnectionResetError

----------------------------------------

ConnectionResetError: [Errno 104] Connection reset by peer

我是否需要重新启动VM并重试但是我将失去经过培训的模型文件,还是有其他方式下载文件？

Answer 1

保存到谷歌驱动器使用Pydrive

# Install the PyDrive wrapper & import libraries.
# This only needs to be done once in a notebook.
!pip install -U -q PyDrive
from pydrive.auth import GoogleAuth
from pydrive.drive import GoogleDrive
from google.colab import auth
from oauth2client.client import GoogleCredentials

# Authenticate and create the PyDrive client.
# This only needs to be done once in a notebook.
auth.authenticate_user()
gauth = GoogleAuth()
gauth.credentials = GoogleCredentials.get_application_default()
drive = GoogleDrive(gauth)

# Create & upload a file.
uploaded = drive.CreateFile({'title': 'filename.csv'})
uploaded.SetContentFile('filename.csv')
uploaded.Upload()
print('Uploaded file with ID {}'.format(uploaded.get('id')))
