Encountered Error "Illegal instruction" when Running Model Optimizer on TensorFlow Model Binaries

Content Type: Error Messages   |   Article ID: 000058875   |   Last Reviewed: 05/20/2022

Environment

OpenVINO 2021.2.185 Up Squared Board with Intel Pentium N4200 (4 cores) Ubuntu 18.04.5 LTS

Description

Encountered error Illegal instruction when running Model optimizer using various TensorFlow models.

Resolution

The TensorFlow prebuilt model binaries are enabled with Intel® Advanced Vector Extensions (Intel® AVX) instructions. When you're configuring the Model Optimizer by running the install_prerequisites or install_prerequisites.tf scripts, they download only the TensorFlow prebuilt binaries with AVX instructions. The Intel® Pentium® Processor N Series (formerly known as Apollo Lake) does not support AVX; therefore, these processors do not support the TensorFlow prebuilt binaries.
