Using the latest version (on Ubuntu, installed from pip3) and I get an error:

I'm 99% sure the issue is that by specifying --type taxa you are not downloading the accession nucl_gb file.

You can get the file from:

• ftp://ftp.ncbi.nih.gov/pub/taxonomy/accession2taxid/
• https://ftp.ncbi.nih.gov/pub/taxonomy/accession2taxid/

The taxdump.tar.gz file is in the parent directory of the above, should you need it.
