Hi @taosun1

Your toolchain does not support sve.

Can you please share the output of the following command aarch64-linux-gnu-g++ --version ?

Hope this helps.

@morgolock thanks, I finally built successfully inside this container https://hub.docker.com/r/armswdev/tensorflow-arm-neoverse. I guess we can close this issue.
