Hello everybody. I am kinda new to the subject of environments. Can someone give me a help with integrating Python with Knime please? I have installed Knime, Anaconda and Python. I am trying to run this workflow [image] Multivariate Time Series Analysis with an RNN - Training – kathrin This is a simple example workflow for multivariant time series analysis using an LSTM based recurrent neural network and implemented via the KNIME Deep Learnin… and I get these errors ERROR Keras Network Learner 3:148 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 ‘tensorflow’ or one of its dependencies is missing. Python library ‘keras’ 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 “KNIME Deep Learning” Preferences.

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 “KNIME Deep Learning” Preferences. When installing python, I installed newest version 3.11.2 and after that in command prompt I pip installed tensorflow and keras. When I go to knime preferences and go to Python settings it asks me to select ( or create new) Python 3 Conda environment. But all it offers as a base are Python 3.6, 3.7, 3.8, and 3.9. The new one I installed (3.11.2) doesnt get offered. And under preferences under PYthon Deep learning it says Python version 3.9.13 and under that Library keras is missing and Library tensorflow is missing. I am kinda confused about what the environment is and how to set it up. I assume that is a problem here. Seems like I have Pythons installed all over. I have stand alone installation, then some of the versions got istalled with Anaconda and some got installed with Knime. And either there is a conflict or all apps should be using the same version? Please help with advice. Best regards, Dario

Hey Dario, well, the conda env you sent has nothing to do with the suggestions from mlauber. In addition to the following, could you also provide the KNIME Analytics Platform version? Would you mind trying to save from mlaubers post above the content # for Keras nodes... until - onnx-tf==1.5 in a file with the name environment.yml Create an environment from that yml file , the name of the environment is py37_knime_dl_cpu (which is described in your yml file) activate that environment in Preferences --> KNIME --> Python Deep Learning --> Keras or where you want it to use send a screenshot of that page to see whether there are errors send more information about the now occurring errors from the KNIME log (see here how to obtain it) Best regards Steffen

Hi @Dalmatino16,

the OpenSSL issues could be because of the used conda version in your environments. consider using an older conda version as described here:
