ODM fails after extracting features with exception : child returned 1

Hello ,
I am trying to process 1000 images in OpenDroneMap using opensfm-dense parameter. But the process fails in between with this error :
Traceback (most recent call last):

Exception: Child returned 1

The ODM is natively installed in a Virtual Environment running ubuntu 16.04.6.
The installation was perfect. I am able to process the data without the “–use-opensfm-dense” .
Any Suggestions? Am i doing something wrong? Here’s link to the sample dataset i have been using. (I can’t share the complete dataset , sorry for that)

One very interesting finding. THe processruns without any error in the EC2 instance , but if I try the same thing in my local system then it fails with that particular error.

Any suggestions why that can happen?

@smathermather Could you help me out on this?

Any suggestions on what can be the problem???
And One more question: Does the processor matter? As in Intel vs AMD for processing?
Because if I am running in AMD processor it fails at that above mentioned step. Otherwise works fine in INtel processors… Is it just a coincidence or the processor matters ?

Thank you.
