When generating link recommendations via querying the MySQL-tables, the model-file is written to the temp-folder (e.g. /tmp/simple.linkmodel.json), such that for subsequent link-recommendations calls for other articles in the same language, the model can be loaded directly without another MySQL-query. When we re-run the training-pipeline we add the updated model to the MySQL table, however, if the old model-file still exists in the tmp-file the DataetLoader will not query the new model but still use the old model.

Possible solution:

• delete model file in tmp-folder when running the training-pipeline for a given language (not sure if recommended)
