requires python3, tkinter; AND cannot run headless

The server I was attempting to benchmark didn’t have these items, that appear to be required. After installing the additional dependencies, it appears tkinter requires a working x display.

😦 I was so close!

My thoughts: After the .json files are generated, send them to another machine with the additional libraries / dependencies for image generation.

Finally: Thank you for creating, publishing, documenting, and blogging about your work. It has been a resource of mine for the past few years.

Thank you, X should not be required, I will try to reproduce and fix it. Which flavour of Linux do you run?

I have released an almost total rewrite that requires python3. I’ve tested it on a clean Linux box and it seems to work fine, without the issues reported above.
