Core dumped on examples


I am trying to start examples from the Jupyter notebook but I receive this kind of error:

/usr/local/bin/tlt-train: line 32:   473 Illegal instruction     (core dumped) tlt-train-g1 ${PYTHON_ARGS[*]}

This is the full log provided by executing this command:

tlt-train detection -e $SPECS_DIR/det_train_resnet18_pascal_voc.txt \
                     -r $USER_EXPERIMENT_DIR/experiment_dir_unpruned \
                     -k $API_KEY \
                     -n resnet18_detector

I am using Xubuntu 16.04, nvidia driver: 384.130, GPU: 1060GTX 6GB
I think this configuration should work and the problem is somewhere else.
I did not touch any of the configuration files, only downloaded PASCAL VOC dataset (as required)

Do you have any ideas what causes this error and how to fix it?


any fix for this? I’m having the same issue. Using GPU: NVidia RTX 2080

Hi amertahir,
The customer nikki_dzhurov created this topic on May 7th. He used TLT EA version.
TLT GA is released on Sep 26th.

So your case is not the same as his. BTW, would you please check if your TLT is GA version?
$ docker pull

See tlt doc for more details.


I think the reason for the problem was missing AVX2 instruction set in my previous Xeon processor. And yes, @Morganh is right, I was using EA version back then. I will try the GA soon probably.

Best Regards

Thanks nikki for the info:)
