keras-vis: ImportError: cannot import name '_Conv' from 'keras.layers.convolutional'

_Conv method not available with later version keras 2.4, the way to solve this is use Conv2D API. You can update the saliency.py module as I did below

$ diff visualization/saliency.py visualization/saliency.py.org

Sorry for late reply.

Try this: pip install keras==2.2.2 & pip install tensorflow==1.10.0

Let me know, the solution worked or not

try this: my version, got from pip list tensorflow 2.4.1 keras 2.4.3 keras-vis 0.5.0

change following lines in saliency.py from Python38\Lib\site-packages\vis\visualization\ 6 from keras.layers.convolutional import Conv2D 7 from keras.layers.pooling import MaxPooling1D, MaxPooling2D, AveragePooling1D, AveragePooling2D and 33 if isinstance(layer, (Conv2D, MaxPooling1D, MaxPooling2D, AveragePooling1D, AveragePooling2D)):

still if you want to use functions like visualize_saliency you may probably get other errors like keras.backend has no attribute identity; which are really hard to solve with current versions of tensorflow and keras, at least I spent ~ 2h and in my case it doesn’t worth anymore.

This lib is far behind the current changes, consider using tf_keras_vis or other visualization libs.

Try this: pip install keras==2.2.2 & pip install tensorflow==1.14.0

solved my issue… installed in Colab

It also works for me although I have to make some changes to my code. I also used Keras 2.2.2 with TensorFlow 2.0 and it was okay too. However, I moved my code to tf.keras and used the method provided in the official Keras documentation and it works like a charm:)

I also have save issue of can’t import ‘_Conv’, but my problem is not solved by Keras 2.2.2 and TensorFlow 2.0. Can you guide me further, what will be the solution without downgrading Tensorflow. Or can you kindly share your code and environment details.
