Getting Invalid dimensions error while trying to open SEGY file

[warda-rezig]

I am trying to follow this tutorial https://www.youtube.com/watch?v=grGa-B4gV9c about "Dislplaying Seismic Data in Jupyter Notebook using SEGYIO Library" and while opening the SEGY file I got this error:

---------------------------------------------------------------------------

Hi,

Segyio requires a regular cube in order to infer geometry. You can tell segyio.open to ignore any geometry. Have a look here:
