I want to install the dependencies for chapter 2.

Mix.install([
  {:nx, "~> 0.5"},
  {:exla, "~> 0.5"},
  {:benchee, "~> 1.0"}
])

Throws the error, that xla has to be bild manually, by setting a variable.

** (RuntimeError) none of the precompiled archives matches your target
Expected:
* xla_extension-x86_64-windows-cpu.tar.gz
Found:
* xla_extension-aarch64-darwin-cpu.tar.gz
* xla_extension-aarch64-linux-gnu-cpu.tar.gz
* xla_extension-x86_64-darwin-cpu.tar.gz
* xla_extension-x86_64-linux-gnu-cpu.tar.gz

You can compile XLA locally by setting an environment variable: XLA_BUILD=true

How is this done?

As alternative I I tried to use torchx:

** (Mix.Error) “nmake” not found in the path. If you have set the MAKE environment variable, please make sure it is correct.
