extent analysis

TL;DR

The issue is likely due to the Intel Arc A770 GPU not supporting double precision floating point operations, causing the Triton Inductor compilation to fail.

Guidance

Check GPU support: Verify that the Intel Arc A770 GPU supports double precision floating point operations.
Use a different data type: Try using a different data type, such as float32, to see if the issue persists.
Update drivers and software: Ensure that the GPU drivers and software are up-to-date, as newer versions may include support for double precision operations.
Use a different compiler: The error message suggests a UnicodeDecodeError, which may be related to the compiler used; try switching to a different compiler, such as clang-cl, to see if the issue resolves.

Example

No code example is provided, as the issue appears to be related to hardware and software configuration rather than code.

Notes

The error message indicates a UnicodeDecodeError, which may be a red herring; the actual issue is likely related to the GPU's support for double precision operations. Additionally, the use of the Intel Arc A770 GPU may be the root cause of the issue, as it may not support the required operations.

Recommendation

Apply a workaround by using a different data type, such as float32, to avoid the double precision operation issue. If possible, consider using a different GPU that supports double precision operations.
