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

I had a similar issue and it turned out that it is due to I have slightly old CPU and that doesn't work very well with 1.6+ versions of TensorFlow https://www.tensorflow.org/install/source

Note: Starting with TensorFlow 1.6, binaries use AVX instructions which may not run on older CPUs.

So as mentioned before you can either install TensorFlow 1.5, or if you still want the latest version of TF, you will need to install it with conda instead (both solutions worked with me)

For conda installation:

conda create -n tensorflow
conda install tensorflow-gpu -n tensorflow
