Problem with vislor

[jmbenlloch]

I have successfully clone the project, installed nix-shell and direnv. I could run as well the mlem examples and the jupyter notebook to compare the results. But when I have tried to run any of the vislor examples I am getting an error:

$ cargo run --bin vislor -- ball

@jacg, are you familiar with this error? What should I do?

[jacg]

I'm have deleted most of the exchanges in this thread, as they were very noisy, and didn't really contribute anything to understanding the problem. I have left the original problem report and the final solution.

[jacg]

Please check out the fix-vislor branch, and try running

nixGL cargo run --bin vislor -- ball

that is, prepend the command you were trying before, with nixGL.

[jmbenlloch]

Everything worked using the fix-vislor branch and the command you provided!
