Hello everyone, I am facing a problem when I run klayout I receive some errors and I can't get rid of them... can someone help me please?

this was the observed behaviour in our case as well. Can you see a klayout window popping up

Here is a screenshot of my case.

yes this is alright, if you want to see a layout do

klayout -e gds_filename.gds

Ohh Thanks my friend I thought the whole time that I am having a problem, I tried an inverter example and it is working fine 🙂
