Have you solved it yet?

I met same problem... I think this problem comes from bazel instead of mediapipe

[FunnyWii]

I Solved this problem via upgrading gcc&g++ from 9 to 10.

Hi @tonystratum,

Can you try out the suggestion mentioned by @FunnyWii, And please let us know if this still an issue?

Thank you!!

[tonystratum]

@kuaashish certainly will try! @FunnyWii have you upgreaded the compiler within docker build environment? If so, how? Thanks

[tonystratum]

@FunnyWii @kuaashish built gcc 10.5.0 inside the debian:buster image, still Error: unrecognized option -march=armv8.2-a+i8mm+fp16

[tonystratum]

@FunnyWii please, could You share the steps for upgrading the toolchain?

@FunnyWii please, could You share the steps for upgrading the toolchain?

sry for the late response, I update gcc via sudo apt install gcc-10

My platform is Jetson Orin NX

[tonystratum]

@FunnyWii Yeah no worries, thanks! @kuaashish I just wanted to know if Coral TPU is still supported at this point. The Coral's Mendel Linux is based on Debian Buster, and the toolchain there (gcc-9) does not compile the fresh XNNPACK (what @FunnyWii is actually saying). We would need to update toolchain on both the Mendel linux and the docker build environment here

Hi @tonystratum,

Currently, the new Task API supports Edge devices such as the Raspberry Pi 4, as mentioned on the referenced page. For legacy solutions, we supported the Coral TPU, If this is the case, we will not be able to assist you, as support for the legacy solution has completely ended.

Thank you!!
