Hey @improve100,

Thanks for using our code.

It seems it can finish the localization but get some problem when deconstructing the GPU buffer after finishing the localization.

Did you get the localization results?

[improve100]

I tried to run several other commands in readme, and the terminal would not automatically exit, but the result came out. and i got the result files demo_loc_results.npz and demo_loc_results_updated.npz.

[Chen-Xieyuanli]

OK, it then finished already the localization process. The problem should be on the OpenGL glow library or the GPU side. It never happened to me before, and I currently have no solution. Let's just keep this issue open and see whether we could find the solution later.
