intel-tensorflo-avx512 bus error

wanben — Wed, 06 Apr 2022 06:56:35 GMT

I run these code and tensorflow with :

pip install intel-tensorflow==2.8.0

will show:

2022-04-06 06:56:10.744124: I tensorflow/core/platform/cpu_feature_guard.cc:151] This TensorFlow binary is optimized with oneAPI Deep Neural Network Library (oneDNN) to use the following CPU instructions in performance-critical operations: AVX2 AVX512F FMA

How can I fix it?

Hi,

Thank you for posting in Intel Communities.

Q: This TensorFlow binary is optimized with oneAPI Deep Neural Network Library (oneDNN) to use the following CPU instructions in performance-critical operations: AVX2 AVX512F FMA

To enable them in other operations, rebuild TensorFlow with the appropriate compiler flags.

A: This is not an error; it is just telling you that it can and will take advantage of your CPU to get that extra speed out.

Q: I tensorflow/core/common_runtime/process_util.cc:146] Creating new thread pool with default inter op setting:

Bus error (core dumped)

A: The issue was mainly with the memory space. Please free up space within the user home path.

We were unable to reproduce the issue from our end.

Details of our machine

Machine details: Cascade Lake

Operating system: Ubuntu 20.04

Base Toolkit version used: 2022.1.2 (https://www.intel.com/content/www/us/en/developer/tools/oneapi/base-toolkit-download.html?operatingsystem=linux&distributions=webdownload&options=online)

Python version available with that base toolkit:3.9

We are trying in Windows machine also. Will update you once we get the results.

Details needed

Could you please share with us the following details so that we investigate the issue from our end?

1. Operating system you are using

2. Python version you are using

Workaround

You could try installing Intel® Optimization for TensorFlow* from Intel® AI Analytics Toolkit from here:

Available for Linux*

TensorFlow* version: 2.6

https://www.intel.com/content/www/us/en/developer/tools/oneapi/ai-analytics-toolkit-download.html?operatingsystem=linux
