   The pyarrow wheels are compiled assuming SSE4.2 is available. You CPU is quite old and does not support that instruction set. You will have to build pyarrow/libarrow yourself see the [docs](https://arrow.apache.org/docs/cpp/env_vars.html#envvar-ARROW_USER_SIMD_LEVEL) on how to control the SIMD level.
