# For the moment we only support the CPU and GPU backends of jaxlib. The TPU
|
|
# backend will require some additional work. Those wheels are located here:
|
|
# https://storage.googleapis.com/jax-releases/libtpu_releases.html.
|
|
|
|
# For future reference, the easiest way to test the GPU backend is to run
|
|
# NIX_PATH=.. nix-shell -p python3 python3Packages.jax "python3Packages.jaxlib-bin.override { cudaSupport = true; }"
|
|
# export XLA_FLAGS=--xla_gpu_force_compilation_parallelism=1
|
|
# python -c "from jax.lib import xla_bridge; assert xla_bridge.get_backend().platform == 'gpu'"
|
|
# python -c "from jax import random; random.PRNGKey(0)"
|
|
# python -c "from jax import random; x = random.normal(random.PRNGKey(0), (100, 100)); x @ x"
|
|
# There's no convenient way to test the GPU backend in the derivation since the
|
|
# nix build environment blocks access to the GPU. See also:
