How can I inspect variables within a Google's Colab notebook? I have tried adding the extension provided by this discussion (Variable Explorer in Jupyter Notebook) to access the variable explorer. Although it has installed successfully, I was not able to use the extension. Is there any other way to do this?
You can install extensions, although widgets don't yet work presently.
The relevant GitHub issue is: https://github.com/googlecolab/colabtools/issues/60
My recommendation is to describe your use-case there to help prioritize.
