Problems encountered while running trace examples

[999-x]

Hello, this is my first time using xrt. When running the 01BD-SourceZCrystalThetaAlpha script in 07-AnalyzerBent2D, it prompted me with an error in the material script，as shown in the following figure. Because this is my first time encountering Python, I cannot find a solution on my own and cannot follow the error prompt to resolve it.I hope you can help me clarify my doubts,thank you very much!

The error prompt looks like this：
UserWarning: Reading .npy or .npz file required additional header parsing as it was created on Python 2. Save the file again to speed up loading and avoid this warning.

Hi,
As it says, this is a warning, not an error. You can simply ignore it.
A better way is to use the current GitHub version, the material files were updated half a year ago, just we haven't made a release since then.

Excuse me, the current GitHub version is xrt-1.6.0 ?

"The current version" means the present set of files. GitHub can save files when the owner creates a new tag. By adding notes, this makes a new release (or version). You don't need the latest release, this is probably what you have already. You need the green button Code, where you can clone or download.
