[3dem] Issue with RelionRefine3D

Hey, I know this issue has been asked recently, but I was wondering if
anyone had any idea as to how to resolve this.  I received this error when
attempting to run 3D auto-refine in Relion:

Dumped data: error_dump_pdf_orientation, error_dump_pdf_orientation and
error_dump_unsorted.
slave 3 encountered error: ERROR:
No orientation was found as better than any other.

A particle image was compared to the reference and resulted in all-zero
weights (for all orientations). This should not happen, unless your data
has very special characteristics. This has historically happened for some
lower-precision calculations, but multiple fallbacks have since been
implemented. Please report this error to the relion developers at

             github.com/3dem/relion/issues

File: /programs/x86_64-linux/relion/2.1_cu8.0/src/gpu_utils/
cuda_ml_optimiser.cu line: 1710

Does anyone have any idea as to what might cause this and any fixes?
