What I Did

Ran:

import yaml
from pywhip import whip_csv

with open("specs.yaml") as whip_specs_file:
    specifications = yaml.load(whip_specs_file)

    observations_whip = whip_csv("occurrence.txt", 
                             specifications, delimiter='\t')
    with open("report_observations.html", "w") as index_page:
        index_page.write(observations_whip.get_report('html'))

With:

country:
   allowed: [BE, NL]
eventDate:
    dateformat: '%Y-%m-%d'
    mindate: 2016-01-01
    maxdate: 2018-12-31
individualCount:
    numberformat: x  # needs to be an integer value
    min: 1
    max: 100
