What can i do?

Hi @AR7 -

Looks like you need to install the mlrose package in your Python environment.

Thank you.
How can i do that?
I am using Anaconda

First, go to KNIME Preferences -> KNIME -> Python and identify the name of the Conda environment that KNIME is using. Once you know that, you can open an Anaconda prompt and give a command like

conda install -n <env_name> <package>

So if your Python environment is called py3_knime, the command would be

conda install -n py3_knime mlrose

Let Anaconda install the package, and when it’s finished, restart KNIME and try running the workflow again.
