i got this error message when importing tangent.

vicky@linux:~$ python -c "import tangent"
Illegal instruction

other modules like numpy, sklearn is working fine.

This might be due to some dependencies clashing when used together. Does importing tensorflow and autograd on their own also work? What about if you try to import all of them in the same terminal?

[vck]

@mdanatg yes, tensorflow too. Autograd isn't affected.

This is likely TensorFlow issue 17411:
tensorflow/tensorflow#17411

TensorFlow official binaries no longer support non-AVX CPUs:
"Starting with TensorFlow 1.6, binaries use AVX instructions which may not run on older CPUs."
