Hi @sampa, you can use captum with and without Insights (interactive tool).
If you want to use it without interactivity, then you can try our tutorials and examples on the README page: https://github.com/pytorch/captum 17
For the insights, I believe that there used to be an option visualizer.render(debug=True). This will help you to see the error log.
Also, in which environment are you trying to run insights ?
