ImportError: cannot import name 'normalize_data_format'

[yuyijie1995]

When I use keras2.2.2 to import the layer instanceNormalization ,the error happened .What should I do?
The full error log like below
File "D:\yuyijie\kerasceshi\keras-yolo3\yolo_IN.py", line 5, in
from keras_contrib.layers.normalization import InstanceNormalization
File "D:\yuyijie\kerasceshi\keras-yolo3\keras_contrib_init_.py", line 4, in

Looks like this was brought up previously (#291) and is part of an open pull request (#292).

Will there be any new release anytime soon to make it compatible with the up-to-date keras version?

keras 2.1.6

I am facing the same issue.Though i have keras 2.1.6 installed. Not able to use keras_contrib

[apoorvadixit21]

if i import keras_contrib, this error comes in spyder and it tell me to do this "from keras.backend.common import normalize_data_format". But when i actually go for this facing the similar issue again.What to do

[keisen]

The currently keras-contrib has compatibility with keras2.2.1+,
then but incompatibility with before keras2.2.0.
So you have to update keras to 2.2.1+ or to downgrade keras-contrib to older than currently.

@keisen Which is the last keras-contrib version that supports keras 2.2.0 and how can I install it? I don't find any relases in this repo. Current master seems to be 2.0.8. Thank you.

[world4jason]

same question here, how do i know which version of keras-contrib match keras 2.0.8?

@maderafunk
my keras version is 2.0.8, and here is my temporary solution
because keras.utils.conv_utils#normalize_data_format() already moved into keras.backend.common in new version of keras.
I just simply edited line 15 in the file "convolutional.py"

#from keras.backend.common import normalize_data_format
from keras.utils.conv_utils import normalize_data_format

that file might locate at "/usr/local/lib/python3.5/dist-packages/keras_contrib/layers/convolutional.py"
and this work for me

Hi, @maderafunk .
It might be 4d48c68 .
So please try below:

pip install git+https://github.com/keras-team/keras-contrib.git@4d48c687433c53a3495357e99cb059ede74e7f02 -U

If I made a mistake , sorry.

[maderafunk]

Thank you, that works @keisen .
Maybe it would make sense to have release tags updated with the keras version, to ensure compatibility?
