when I run TransformerVisualization.ipynb, it shows right output_string, but doesn't show any visualizations.

I am having the same problem, was able to see the following javascript errors in the console When running

%%javascript
require.config({
  paths: {
      d3: '//cdnjs.cloudflare.com/ajax/libs/d3/3.4.8/d3.min'
  }
});

The following is returned:

And then when calling

attention.show(inp_text, out_text, *att_mats)
