I just solved my case which was actually that I accidentally have set KNIME_PYTHON_PACKAGE_REPO_URL despite not wanting to do an offline installation (and not having downloaded any packages on a machine that has access to internet / can install the normal way).
Reading through the above again I get that you are actually trying an offline installation - one thing that I am not yet clear on:
- did you download the GenAI extension on a machine that has internet access?
- Did you then move it from that machine to the machine w/o internet access?
- Did you then, on the machine w/o internet access set KNIME_PYTHON_PACKAGE_REPO_URL to the folder you have moved the downloaded packages to?
I see that the documentation has been linked above already, but just wanted to check in…
