Can I ignore warnings for jaxlib and TPU?

[ToshiyukiBandai]

Hi all,

JAX gives me the following two warnings. I get them when running on both CPU and GPU. Can I safely ignore them? Or, do they indicate some issues in my GPU or performance degradation? In fact, nvidia-smi indicates that there is a segmentation fault, which I don't know what it means...

I0712 19:59:38.064383 140590477190976 xla_bridge.py:884] Unable to initialize backend 'rocm': module 'jaxlib.xla_extension' has no attribute 'GpuAllocatorConfig'

Segmentation fault

It's safe to ignore. rocm is for amd device, and tpu is for google's cloud tpu, neither relevant with nvidia device.

However, segmentation fault in nvidia-smi might point to an issue with nvidia software, probably unrelated to jax.

I see, thank you!
