AttributeError: module ‘keras.optimizers’ has no attribute ‘Adam’

[akhtarameen]

I am getting an error when running the “Keras Network Learner” on KNIME. It gives the following error:

ERROR Keras Network Learner 6:16 module ‘keras.optimizers’ has no attribute ‘Adam’
Traceback (most recent call last):
File “”, line 7, in
AttributeError: module ‘keras.optimizers’ has no attribute ‘Adam’

Will appreciate if anyone can help me fix this. I am really not sure which python file I should be looking into, to fix the issue with importing the modules for the training process, as that is what is hinted by the error above. Thanks in advance!

I guess Adam is a class not an Attribute so you need to call it (instanciate it)
sth like
Adam()
If you use KNIME (no python script) you probably should share your work here to get help

@akhtarameen as it happens I just have collected some example how to set up Keras and Tensor Flow 2 (for classification tasks) with the help of the Conda Environment propagation.

If you have a working Miniconda or Anaconda environment configured in KNIME you should be able to just use the propagation and get a working deep learning setup.

You would then have to carefully check and plan what you want to d with the setup and what architecture you want to use.

a simple deep learning network for binary classification using the KNIME...

The setup in the KNIME preferences would look something like this. You can generate a deep learning environment here or try to let the Conda environment propagation do the job for you once you have a basic Miniconda running (regardless of the Python version).

The same thing should also work with Tensor Flow:

Train a simple Multilayer Perceptron using TensorFlow 2 – mlauber71

If you just want (some) Deep Learning without configurations and Python you can just force H2O.ai AutoML to do the job

use H2O.ai auto-machine-learning to just generate deep learning models –...

@mlauber71 ,
Have you experienced any benefits in using KNIME instead of scripting the python code directly?

[mlauber71]

@Daniel_Weikert I think like it is so often the case KNIME provides the platform and the workflow. You can do a lot of things just using Python but KNIME makes it easier to integrate that with other functions.
