Python deep learning extensions on Mac

I am writing to seek assistance with downloading the Python deep learning extensions

in KNIME. Despite having installed Anaconda on my system, I am encountering difficulties accessing these extensions.

Could you please provide guidance on resolving this issue? I have followed the installation instructions carefully, but I am still unable to proceed.

To provide further context, I have attached a screenshot illustrating the problem I am facing.

Thank you for your attention to this matter.
