a CNN should be used instead of the BERT model in the train.py script, because it can handle the type of data better.
The CNN should not be too complex, but also not too simple and should be generated using Tensorflow.
The CNN should be integrated into the logic and adapted according to the word vectors used. Change the code of it, as good as you can.
