Missing import statements for TextCNN and numpy

[cclauss]

• TextCNN is not properly imported in ./a02_TextCNN/p7_TextCNN_model_multilayers.py
• numpy is not properly imported as np in ./a00_boosting/a08_boosting.py
• predict is an undefined name in ./a07_Transformer/a2_predict.py
• reload() was moved in Python 3
