Hello everyone,

I tried following the tutorial provided here: py4vasp/0.4.0/; I am following the tutorial on Jupyter Notebook, and I am using a DOS calculation that I have completed.
In the last step, it is said that calc.dos.plot() will return an interactive figure of the plot. However instead of the plot, what I get is (possibly) the input for the graph/figure. Is there a step I am missing? Here is what calc.dos.plot() returns when I tried it:

>>> calc.dos.plot()

Hello!

Are you sure you are running these commands from within a Jupyter notebook environment? This output I would expect if you are running directly from the Python console (indicated by the leading >>>).

Please try to follow the steps listed here before running the py4vasp commands: https://vasp.at/forum/viewtopic.php?p=25889#p25889

Let me know if the issue persists!

All the best,
Andreas Singraber

Thank you!
I was inexperienced and could not tell the difference between the console and the notebook environment. It is as you said, I tried plotting it on the console, which did not work...
Thank you very much for your help!
