Illegal instruction (core dumped) after running import tensorflow

Question

I created a fresh virtual environment: virtualenv -p python2 test_venv/ And installed tensorflow: pip install --upgrade --no-cache-dir tensorflow

Answer 1

Unfortunately, 1.6 has given many people the same error. I received it after installing 1.7 on a machine with an old Core2 CPU. I've settled with 1.5, as I can't fit the big graphics card in the machine with the up-to-date processor!
