Core dumped (onmt-train)

Hello there,

I have looked at other subjects but could not find the answer to my issue.

I have installed OpenNMT-py via pip on a server (running on Ubuntu 18.04). I launched the preprocessing, which worked beautifully, but with the training I get the following error (first picture is the error, second is the dmesg result) :

(Again, I tried to take a look online for this issue but could not find an appropriate solution).

Does anyone know what the issue is ? Could someone help me ?

I have OpenNMT-py installed on my mac on everything works fine with the same data (but I cannot use it since this is a small test set to see if everything works, but I will end up using a much larger dataset, hence putting everything on a server).

I have successfully (or so said the terminal) installed OpenNMT-tf, but when typing
onmt-main -help
I also get the Illegal instruction (core dumped) result…

Anyone has any idea why ? I tried to uninstall and reinstall but it’s not working at all

You should probably check your VM documentation to emulate the host CPU. The emulated processor shown above does not have sufficient features.
