Why am I getting an “Error loading notebook” error

Question

I am following the tutorial here:

https://codelabs.developers.google.com/codelabs/cloud-ml-engine-image-classification/index.html?index=..%2F..%2Findex#0

and it is claiming that it will allow me to do image classification on the google cloud. I follow the instructions but when I get to step 4 where I "Start a datalab notebook". It tells me to open the docs folder in Google Cloud DataLab and then open the file called: Hello World.ipynb.

WHen I open this file I get a really weird error that I can't find anything googling. The error is a modal that says:

Error loading notebook

Type u'notebook&_=1495520163792' is invalid

No code loads either from the file. What the heck??? What am I doing wrong?

Answer 1

Can you browse http://localhost:8081/_info and paste the debug information here if possible?

Also, can you create a new Datalab notebook from the "Notebook" menu?

Answer 2

There are two other ways of starting Datalab (the codelab above assumes option #1):

https://codelabs.developers.google.com/codelabs/cpb100-datalab/index.html

Perhaps you will have better luck following Option 2, to run it from CloudShell. Once Datalab is launched, you should be able to continue with the original codelab.

Answer 3

This seemed to happen when connecting to Datalab using Cloud Shell, and should now be fixed.
