AttributeError: module 'tf_keras.backend' has no attribute 'logsumexp'
Closed this issue · 6 comments
In colab, first pip install tf-keras , then
import tf-keras as keras
dir(keras.backend) #No logsumexp
keras.backend.backend() #tensorflow
from keras import backend as K
K.logsumexp #AttributeError
import tensorflow as tf
tf.__version__ #2.15.0
keras.__version__ #2.15.1
No logsumexp found, but still there is.
How to get this function?

Thanks for your reply. from keras import backend as K do include logsumexp in early days before Keras merging into Tensorflow and this is routine going to backend for logsumexp, e.g., here, here and here, etc. However, backend of Keras became inconsistent since Keras 2, I think? See this issue reported 3 years ago.
In a word, since function logsumexp is not decorated as like others in backend, how can we import logsumexp in Keras 2?
@gitfourteen,
logsumexp method was deprecated from keras.backend. Please use it the same function under TF. Please check here for more information. Thank you!
