AttributeError: module 'keras.backend' has no attribute 'get_graph'

Hi. I encounter this error when importing SciANN:

AttributeError: module 'keras.backend' has no attribute 'get_graph'

I have installed the latest version of keras and Tensorflow. Can anyone help me?

Here is the full text of the error:

I also got the same error.

hi, I got the same error

[ziqiang-shi]

I also got the same error. Did you solve it?

[ehsanhaghighat]

It is most likely due to the latest TF changes. Can you try fresh with Python==3.9 or 3.10 and use `pip install -r requirements.txt` from this project: https://github.com/ehsanhaghighat/En-DeepONet

Hi,

I had the same issue. For my project environment I used

python==3.7 numpy==1.21.6 sciann==0.7.0.1 matplotlib==3.5.3 scipy==1.7.3 pandas==1.3.5 plotly==5.18.0 tensorflow==2.11.0

And, It worked perfectly.

I had the same issue in Google Colab that currently has TF 2.14 by default. I installed TF 2.11 and it worked.

I had to uninstall tensorflow-datasets and tensorflow-metadata that had conflicting versions with tensorflow==2.11. Overall I did:

pip uninstall tensorflow-datasets tensorflow-metadata -y
pip install tensorflow==2.11
pip install sciann
