Issue with loading library keras-contrib

[iamyihwa]

Hello David! Thanks for the great book!

I have ran an error when running CycleGan notebook: 05_01_cyclegan_train.ipynb
It is due to an error 'keras_contrib' library not found.

So I have installed the library separately, from the github of keras-contrib .

import os
import matplotlib.pyplot as plt

from models.cycleGAN import CycleGAN
from utils.loaders import DataLoader

---------------------------------------------------------------------------
ModuleNotFoundError                       Traceback (most recent call last)
<ipython-input-6-647ffcce73df> in <module>
      2 import matplotlib.pyplot as plt
      3 
----> 4 from models.cycleGAN import CycleGAN
      5 from utils.loaders import DataLoader

~/GAN/GDL_code/models/cycleGAN.py in <module>
      5 #have replaced above with below line on 2019 7 8
      6 #due to an error
----> 7 from keras_contrib.layers.normalization.instancenormalization import InstanceNormalization
      8 from keras.layers import Input, Dense, Reshape, Flatten, Dropout, Concatenate
      9 from keras.layers import BatchNormalization, Activation, ZeroPadding2D, Add

ModuleNotFoundError: No module named 'keras_contrib'

After installing the library, it seems to work okay, but need to change slightly the command
following this
From this :

from keras_contrib.layers.normalization import InstanceNormalization
To this:
from keras_contrib.layers.normalization.instancenormalization import InstanceNormalization

However from the notebook it still doesn't work.
I have tried it both from the same conda environment ..
Any ideas?

I had to install the keras_contrib module independently 😣.
Install keras_contrib via:

sudo pip install git+https://www.github.com/keras-team/keras-contrib.git

I haven't yet reached the cycleGAN example yet. Do let me know if it worked for you. 🙆‍♀️
