There appear to be a couple bugs in get_iers_eop_IAU2000A. In order to get it to work, I had to change the URL to "https://datacenter.iers.org/products/eop/rapid/standard/csv/finals2000A.all.csv" and shift the indices of the last 4 fields in EOPDATA by 4 columns. Although a more robust fix would be to use the values in the header to get the indices of the columns just in case the format changes again.
Thank you for reporting, we have actually already fixed that with #25, and that update will be included in a new patch of the package that will be published soon.
