Ran above code but got error

I have succesfully installed the stellargraph using the same code from last 1-1.5 months but this error is occuring from last day on same code that was working fine earlier

I am having a similar problem on CoLab. I was able to !pip install stellargraph before, but now get an error.

I found this to be helpful to run StellarGraph on Colab: #2084
