@IanSMoyes,
Could you please share the make and model of the CPU on your machine and output of the cat /proc/cpuinfo command with us.

Starting with v1.6, TensorFlow binaries use AVX instructions which may not run on older CPUs. For more information, please take a look at the hardware requirements for installing TensorFlow. Also check similar issues #33038, #29788 for reference.

Thanks!

Your CPU does not support AVX. You have to compile from source or use a newer machine / a VM in the cloud.

@IanSMoyes,
Please follow this guide to build TensorFlow from source on Linux machines.

Make sure you have all the required dependencies installed as mentioned in the tested build configurations. Thanks!
