      I don't know if you have seen this error, but I'll put it here so that we have a record. On this line (line 34), the program fails with an error of

        Haven't seen this. I will do more testing to see what's going on.

        Did you use the extracted NRL V2 archive? I haven't implemented the entire functionality in this MR. It needs to download the archive first and extract it and then pass the Path of the folder as root to NRL() method. The default is also online NRL v1 which needs to be fixed.
