Keras 2 API tips

“Old” Keras Dense declaration in Keras 2 API :

model.add(Dense(11, input_dim=11, init=”uniform”, activation=”relu”))

is now:

Dense(11, input_dim=11, activation=”relu”, kernel_initializer=”uniform”)

If when adding you

  • TypeError: add() got an unexpected keyword argument ‘init’

How to install nltk (Windows and Mac)

If you are getting this error: ‘tokenizers/punkt/PY3/english.pickle’

Most likely is because you haven’t downloaded necessary nltk packages, don’t worry is quite easy:

  • Open a terminal (cmd in Windows)
  • Run Python by typing in the terminal Window python then write everything belo
    • conda install -c anaconda nltk
    • import nltk
  • Look for a new program that will pop up and btw show available packages from here:
  • I installed the “popular” option and that got rid of the issue

Happy coding,
