ImportError: cannot import name 'SpacyTokenizer'

[maykonmichel]

Hello, I'm trying to follow your excellent medium post, but I'm getting this ImportError: cannot import name 'SpacyTokenizer' error when I run make train

$ make train

Enter model file: experiments/greetings/copynet.json
Enter model directory (default is /tmp/models/copynet): 
Serializing model to /tmp/models/copynet/run_001
Is this correct? [Y/n] Y
