error installing Knime AI extension

Can you try a folder outside the KNIME folder without any blanks.

Then maybe you can try the whole thing with the version 5.3.3 (in any case we hope that the December version of 5.4 will make things much easier)

The file does not show much other than that the packages are being used locally which is what we want. Maybe you can set up a fresh log file in debug mode to identify possible problems.
