hey @zakarianamikaz ,
check this directory: https://github.com/oudalab/Arabic-NER/tree/master/ar_output_all/model0
the model after training should have the accurary.json, urs does not have it, better way is you debug and figure out why u are mission that file, suggest you read a little bit about how spacy works with its model traning.
