Vx delegate issue

Mohan51 — Thu, 14 Mar 2024 08:57:57 GMT

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:

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?

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 — Fri, 22 Mar 2024 04:50:46 GMT

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