I could sucessfully install armnn and pyarmnn for 32 bit raspberry pi os and could run a tflite model. Is there a pyarmnn and armnn version that could be installed on 64 bit raspberry pi os. Please provide the link
There are pre-built binaries available for bullseye version of Debian, which you can download and install with apt-get... Unfortunately the latest Raspbian is still Buster, so if you want to try out armnn and pyarmnn, you could add bullseye to sources.list like that

sudo apt-get update && sudo apt-get install python3-pyarmnn libarmnn-cpuacc-backend22 libarmnn-cpuref-backend22Obviously it's a hack and stability of a system is not guaranteed - so this "method" is only good for testing.
