Dear all,
I want to plot interpolated |A(v,c,k)| on the interpolated electronic band structure for the selected exciton state following, https://www.yambo-code.eu/wiki/index.ph ... _databases.
But, by using exc_kspace_plot.py, it shows an error:
"Traceback (most recent call last):
File "exc_kspace_plot.py", line 90, in <module>
exc_on_bands = yexc.interpolate(yel,path,states,lpratio=50,f=None,size=0.5,verbose=True)

I think it is caulsed by abipy, but I did install it successfully.
By the way, the DFT code is QE(pw.x) and the uninterpolated electronic band structure with the selected exciton state is plotted successfully.
The exc_kspace_plot.py file is attached.
Any sugesstion is appreciated.
Best,
