Got an error when trying to do pixie install.

Developers attempting to participate in Intrinsic's AI for Industry Challenge (AIC) are hitting a significant technical roadblock. The challenge's official toolkit, hosted on GitHub, fails to install on Linux systems using ARM64 (aarch64) architectures. When users run the required `pixi install` command after cloning the repository, they encounter a clear error: "The workspace does not support 'linux-aarch64'." The system currently only lists 'linux-64' and 'osx-arm64' as supported platforms, effectively locking out a segment of developers using popular hardware like Raspberry Pi 4 boards or other ARM-based Linux machines.

This issue, documented in the challenge's discussion forums, reveals a gap in the toolkit's cross-platform compatibility. The error message suggests a workaround—adding the platform manually with `pixi workspace platform add`—but this is a developer-facing fix, not a solution for all participants. The problem is compounded by its timing, as the challenge is active and this barrier prevents entry for those on affordable or embedded ARM hardware. The discussion links to broader topics about the difficulty of running ROS (Robot Operating System) on Pi 4, highlighting a persistent pain point in the robotics and industrial AI development community where ARM support is often an afterthought.
