Thanks for adding me in the post. I have stopped using the forum since the change, and would not know that you had raised a question.
You need to check you conda environment to ensure that you are consistent with the base packages required by KNIME. Note, in KNIIME 4.7 the Python version is 3.9, whereas, your conda environment is 3.8.
In addition to the standard Python environment you will also need to add a package to convert the html output from Plotly into an image file format. This package is Kaleido. Whilst Kaleido is a very popular package for producing image files from Plotly charts the maintainer has stepped away from the project following a change of job (about two years ago). The package is no longer actively maintained and may break at any point in time. It is a warning to all who rely upon it.
The conda command to install Kaleido is not obvious : conda install -c conda-forge python-kaleido
Thank you for your answer. I had installed kaleido; as I read that it is taken this package by default, but I don’t remember installing it with the mentioned command. Thanks as well for the warning about maintenance discontinuity. Break of the code for this reason would be sad.
I will also install conda back again, with updated Py version. I overrode the QC on base packages assuming they are all included, when creating the environment from KNIME button instead from cmd Anaconda terminal. I’ll dive into as well.
