spool load GMTSAR interferogram error

[Stephen0255]

Hi,
I install pyrocko and kite using commands below on a ubuntu-24.04 machine
conda install -c pyrocko pyrocko
conda activate pyrocko
pip install utm
pip install kite,
when I load the GMTSAR interferogram, it shows:

(pyrocko) zs@zs-VM:/work/pyrocko/kite$ ls
phasefilt_mask_ll.grd
(pyrocko) zs@zs-VM:/work/pyrocko/kite$ spool --load phasefilt_mask_ll.grd

how to resolve it? Thanks in advance.

Please try installing pyqtgraph==0.12.4 and rerun. Does it resolve it?

Thanks for your reply.
I install it using "pip install pyqtgraph==0.12.4" and rerun spool, it shows another error:

any suggestions?

Kite only supports netcdf3, which is very old admittedly. From your traceback: TypeError(f"Error: {self.filename} is not a valid NetCDF 3 file")

Also python3.14 is very optimistic to run ;) .
