Why does Milvus return an illegal instruction error during startup?
Milvus requires your CPU to support a SIMD instruction set: SSE4.2, AVX, AVX2, or AVX512. CPU must support at least one of these to ensure that Milvus operates normally. An illegal instruction error returned during startup suggests that your CPU does not support any of the above four instruction sets.
You can see Milvus CPU Support - #2 by rrchan for more info about how to check that your CPU is supported.
