Save failed in Google Colab

Question

I opened a number of tabs at the same time. I think that's why Google Colab was not able to support the heavy load. The message stated:

Please use the File menu to download the .ipynb and upload the notebook to make a copy that includes your recent changes.

Answer 1

It turned out to be a network issue. Output is heavy and colab is not able to save it is not able to make a handshake because internet speed is poor. So just switch the internet source and see it working.

Answer 2

This can happen if you open the same notebook in multiple tabs and make incompatible edits to the notebook. At this point, the only way to save your work is to follow the advice in the dialog. To prevent this in the future, avoid simultaneously editing the same notebook in multiple browser windows.

Answer 3

I got the same issue and eventually I found it's because I set up the hardware accelerator.
This would be fixed if reseting the 'Runtime/Change runtime type' to 'None'.

Answer 4

I had the same problem despite ''Runtime > Change runtime type' being already set 'None' beforehand. As the OP I had no other instances of the notebook open.

In the end I did 3 things in the following order:

1. File > Save a copy in Drive
2. File > Save a copy in GitHub
3. File > Save

Just picking the 'Save' from the drop down again did the trick for me. My variables were still loaded all is working as before.

Answer 5

我删除了（重）输出，它成功了，它开始保存而没有失败通知
