Illegal instruction (core dumped)

I’m trying to do the tutorial at https://awslabs.github.io/sockeye/tutorials/seqcopy.html.

Here is what I did:

git clone https://github.com/awslabs/sockeye.git
cd sockeye
pip3 install -r requirements/requirements.txt
pip3 install .

The following message shoes up.

cd ..
mkdir seqcopytask
cd seqcopytask
wget https://raw.githubusercontent.com/awslabs/sockeye/master/docs/tutorials/seqcopy/genseqcopy.py
python3 genseqcopy.py

python3 -m sockeye.train -s data/train.source \
>                          -t data/train.target \

Illegal instruction (core dumped)

Is there a way to debug this?

Also, please mention your OS, hardware, etc. One way to compile all of this information is to run:

curl --retry 10 -s https://raw.githubusercontent.com/apache/incubator-mxnet/master/tools/diagnose.py | python3

as recommended in the MXnet repo. Secondly, you could try to obtain a stacktrace by setting:

DMLC_LOG_STACK_TRACE_DEPTH=100

then running your training again.
