However even if I installed Miniconda 3 (Python 3.9.12), all KNIME extensions and set up them I have this error if I run the Kera Learner
ERROR Keras Network Learner 3:32 Execute failed: An error occurred while creating the Keras network from its layer specifications. Details: Deep learning Python back end installation tests failed. Cause: Python library âtensorflowâ or one of its dependencies is missing. Python library âkerasâ or one of its dependencies is missing. In case Python packages are missing: you can create a new Python Conda environment that contains all packages required by the KNIME deep learning integrations in the âKNIME Deep Learningâ Preferences.
If I perform conda list -n py3_knime I saw that there wasnât neither keras neither tensorflow. I was able to install package keras using
conda install --name py3_knime keras
but I faced an error with
conda install --name py3_knime tensorflow-mkl
Shouldnât KNIME install them when a new environment is created? Is there any suitable log to solve it?
Thank you! I tried both of the workflow and I was unable to work with both of them.
This is the log

@giuliovialetto this very much looks like the Python configuration is not up to date. I am planning on updating the examples and writing a proper article about the setup of the KNIME deep learning environment which still is somewhat confusing sometimes and constantly evolving it seems
What I would suggest in the meantime is reading about KNIME and Python and conda in my article. Then I would recommend resetting the mentioned workflows and see if the environment propagation would build the correct python environment (make sure to use the one for your operating system):
A condensed version about what to do to setup KNIME and deep learning is here though it is not a fully articulated set of instructions (working on that):
