Have you correctly updated your environment to include the location of the required headers for hip? The error message is saying it can’t find a header that is required.

From the [documentation](https://pyfr.readthedocs.io/en/latest/installation.html#hip-backend):

> The HIP backend targets AMD GPUs which are supported by the ROCm stack. The backend requires: **ROCm \>= 4.5.0**

however from your screenshot it appears as if you are using `4.3.1`.
