Hi all, I'm new to analog design and I was following along with this analog tutorial . But I am running into this issue where when I try and display the values of the circuit I am getting this output shown below. I also encountered a similar thing when trying to create my own test bench based on this https://iic-jku.github.io/analog-circuit-design/#large-signal-mosfet-model where I was unable to get the output values like gm. Any help would be appreciated, thanks!

Try print, instead of display.
