Hi,

Rencenly, I want to compile C/C++ DEMO about label_image of Tensorflow .

But This document getting information is too old , Can you tell me usage about tensorflow 2.4.1 ? Thank

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.

Regards

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 ?

Hi, @Bio_TICFSL

i have confirmed add it . so I know this toolchian's problem of "tensorflow-lite-staticdev"

BSP : L5.10.35.2.0.0

Platform : NXP i.MX8MPlus

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 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
