Vx delegate issue

[Mohan51]

Hi, I want to build ML models to GPU. for that I am trying to build Vx delegate by following the document(https://www.nxp.com/docs/en/user-guide/IMX-MACHINE-LEARNING-UG.pdf). but facing aarch64 errors.I will paste the error below..please provide any updated document for IMX-MACHINE-LEARNING-UG.it will help for us to build the Vx delegate.and I am using Linux and I am using IMX8M nano board

Error:

Always getting this error Compiling tensorflow/compiler/mlir/tensorflow/ir/tf_ops.cc [for host] failed: (Exit 1): gcc failed: error executing command..please help me.I am referring "https://www.nxp.com/docs/en/user-guide/IMX-MACHINE-LEARNING-UG.pdf" 2.6.2.3 step2 while using bazel

Hi @brian14  getting this error while building Vx delegate reduced flux-ERROR: /tensorflow/tensorflow/compiler/mlir/tensorflow/BUILD:593:11: Compiling tensorflow/compiler/mlir/tensorflow/ir/tf_ops.cc [for host] failed: (Exit 1): gcc failed: error executing command

[Mohan51]

please someone could help me to findout a way for building Vx delegate..tried many ways but end up with this error

[brian14]

Hi @Mohan51, 

Thank you for contacting NXP Support.

Here is the latest manual from our website:
i.MX Machine Learning User's Guide (nxp.com)

Could you please point me to the chapter or section that you are following?

[Mohan51]

Hi @brian14  thank you for your reply. I got stuck while doing 2.6.2.3  in Page-9

Step2:"Build the benchmark_model_plus_flex target with a full TensorFlow Operator Set" .

Command: bazel --output_base=/tensorflow/docker-build/ build --config=monolithic
--config=elinux_aarch64 -c opt --cxxopt='--std=c++17' --
host_crosstool_top=@bazel_tools//tools/cpp:toolchain //tensorflow/lite/
delegates/flex/test:benchmark_model_plus_flex_full

I am getting error while doing this step.All the steps and configurations before this step is done successfully.I am posting the error again for your reference.

Hi @Mohan51, 

I'm trying to replicate the issue.
In the meantime, could you please try with the BSP version L6.1.36_2.1.0​?

Have a great day!

[Mohan51]

Hi, I am unable to find the BSP L6. so cloning the latest branch lf-6.6.3.-1.0.0
