[leandrolcampos]

The name of my device now:

--- DEVICE ---

Number of devices: 1
  Name:     �]}�2V

Before it was something like NVIDIA GeForce RTX 4070 Laptop GPU.

[RossBrunton]

Should be fixed by #145913 ; sorry about that - I don't have a Nvidia device for testing.

I think there's also another issue with the version number which may cause failures, which I'm currently working on and will push a fix for soon.

Edit: #146049 for the other change.

[RossBrunton]

Both issues should be fixed, so the test should pass now on Nvidia.

[leandrolcampos]

Thanks for the update, @RossBrunton!
