RepeatModeler-2.0 BuildDatabase error

Question

[1041853545]

I am new to bioinformatics and have installed RepeatModeler successfully however when I run the code

./BuildDatabase -name lh -engine ncbi out.fa

I got a error:

Number of sequences (bp) added to database: 0 ( 0 bp )

I try to read the help about https://github.com/Dfam-consortium/RepeatModeler/issues/13 but it doesn't work. Someone please advise on how to fix this. Thanks

My first guess is that the file "out.fa" is empty or not in FASTA format.
