How to use Google Colab on local machine

I'm working on deep-learning projects with Google Colaboratory. Because there isn't enough storage space on Google Cloud for my training datasets, I try to use Colab on my local machine.

I followed these tips provided by Google to connect Colab with my computer: https://research.google.com/colaboratory/local-runtimes.html

but I failed at Step 4. The Colab page raised:

Unable to connect to the runtime.

Meanwhile my Ubuntu terminal raised:

[W 22:41:53.396 NotebookApp]Forbidden

[W 22:41:53.396 NotebookApp] 403 GET /api/kernelspecs (10.133.6.71) 1.45ms referer=None

How can I successfully connect Colab with my pc?

Solution

Your invocation of jupyter needs particular arguments to authorize Colab to speak to it. Did you start jupyter with the args indicated?

jupyter notebook \
  --NotebookApp.allow_origin='https://colab.research.google.com' \
  --port=8888 \
  --NotebookApp.port_retries=0

Given that a 403 is a permissions error, I suspect you might be missing the NotebookApp.allow_origin option.
