Hello Weilly_li

The documentation includes tensorflow 1.12v because is the version installed on the NU of the MX8MP, there is no actualization to 2.4v but in general the demo should work.

Dear All,

I solved this problem about the newest bsp can't compile tensorflow DEMO issue by myself.

Please follow step

(1) Build BSP L5.10.35.2.0.0 SDK of i.MX8MPlus

      $ source ./imx-setup-release.sh -b bld-xwayland      $ Add in local.conf
         IMAGE_INSTALL_append += " packagegroup-imx-ml"
         TOOLCHAIN_TARGET_TASK_append += "tensorflow-lite-dev armnn-dev  onnxruntime-dev"

      $  bitbake -c populate_sdk imx-image-full

       Tip :  tensorflow-lite-staticdev package has some problem for this version 

(2) Install SDK

      $  cd /home/weilly/fsl-yocto-8mp/bld-xwayland/tmp/deploy/sdk

      $ ./fsl-imx-xwayland-glibc-x86_64-imx-image-full-cortexa53-crypto-imx8mpevk-toolchain-5.10-hardknott.sh

(3) Setting Environment

     $ source /opt/fsl-imx-xwayland/5.10-hardknott/environment-setup-cortexa53-crypto-poky-linux

(4) Download Tensorflow Lite Source Code

     $ git clone https://github.com/tensorflow/tensorflow 

     $ git checkout v2.4.0

(5) Compile Code

     $ cd /tensorflow/tensorflow/lite/examples/label_image

    $ $CC -o label_image_weilly label_image.cc bitmap_helpers.cc ../../tools/evaluation/utils.cc \

        -I=/usr/include/tensorflow/lite/tools/make/downloads/flatbuffers/include \

        -I=/usr/include/tensorflow/lite/tools/make/downloads/absl \

        -ltensorflow-lite -lstdc++ -lpthread -lm -ldl -lrt

Hi, @Bio_TICFSL 

      還有什麼方式可以幫忙解決嗎? 不然無法生出 SDK ~ 去編譯 Tensorflow ~感恩

Dear Bio_TICFSL,

Thank your reply!!  but I still need newest compile method of tensorflow c++ .
Today, I tryed compile label_image code using bazel, it can work on i.MX8M Plus. Unfortunately this method can't use NPU ....do you have some suggest ?
