The used dataset raalst/squad_v2_dutch was kindly provided by Henryk 
it contains train and validation. 
I declared 20% of Train to function as Test
when using raalst/squad_v2_dutch, be sure to clean up quotes and double quotes in the contexts

def cleanup(mylist):
    for item in mylist:
        if '"' in item["context"]:
            item["context"] = item["context"].replace('"','\\"')
        if "'" in item["context"]:
            item["context"] = item["context"].replace("'","\\'")             

The pretrained model was pdelobelle/robbert-v2-dutch-base, a dutch RoBERTa model  

results obtained in training are :
