Linux KNIME 3D-e-Chem Warnings

[rjrich]

After installing the 3d-e-Chem nodes in KNIME 3.6.0 for Linux (Linux Mint 19 64-bit Xfce, based on Ubuntu 18.04 64-bit), upon starting KNIME, I get the following warnings in the KNIME console:

1:26:9 Selected directory '/tmp/knime_tc_b3vo54jya1wd' cannot be accessed!
WARN Create File Name 1:27:9 Selected directory '/tmp/knime_tc_lp6wiiklplaw' cannot be accessed!
WARN Create File Name 1:28:9 Selected directory '/tmp/knime_tc_f1sfo1jxwhgi' cannot be accessed!
WARN Create File Name 1:29:9 Selected directory '/tmp/knime_tc_gxeax8fygbge' cannot be accessed!
WARN Qed Calculator 1:30 Could not find templates folder templates/ in plugin org.knime.knip.knimepython

WARN Create File Name 1:32:9 Selected directory '/tmp/knime_tc_cnvpshoxpxo8' cannot be accessed!

Can these warnings safely be ignored? If not, how can I correct this problem?

Thank you.

You can ignore these warnings.

These are a result of the Silicos-IT nodes being implemented as metanodes which contain Create file name nodes. During KNIME startup these nodes perform unsuccessful validations.

The directories that cannot be accessed will be created in the metanodes before the Create file name nodes execute, so the nodes work as expected. This is a problem that I have been unable fix, see 3D-e-Chem/knime-silicos-it#6

The warning WARN Qed Calculator 1:30 Could not find templates folder templates/ in plugin org.knime.knip.knimepython I cannot reproduce with a clean KNIME install with just 3D-e-Chem nodes installed.

The QED Calculator node does not use Python templates. org.knime.knip.knimepython is the namespace of the KNIME Image Processing feature. When I install the KNIME Image Processing - Python Extensions feature I get the same warning.

Created issue 3D-e-Chem/knime-silicos-it#7 for this warning.
