ROC Curve bug in 4.2.1 when generating an image

KNIME Analytics Platform
1

Hi KNIMEler,
I’m using KNIME 4.2.1 on a Windows machine. When running the ‘ROC Curve’ (Java Script) node - with the flag ‘generate image’ set - the first time after loading the workflow, the (i) execution time is ‘endless’ (~30sec for ~8000 records) and (ii) the image generation fails and in the KNIME.LOG the following traces are shown.

2020-09-01 19:12:44,031 : ERROR : KNIME-Worker-8-ROC Curve 5:25 : : AbstractImageWizardNodeModel : ROC Curve : 5:25 : Initializing view failed: timeout: Timed out receiving message from renderer: 60.000

Re-executing the ‘ROC Curve’ node again (after reset) succeeds (after 3 secs!) with a generated image.
It seems to me, that there are some ‘Chrome’ initialization issue with the bundeled version.

Hi Erich,

on Windows we frequently encounter problems with Windows Defender slowing down the startup of Chromium. To verify that this is the problem you can temporarily turn off Defender and try to generate the image and compare runtimes. Once confirmed, you can set exceptions in Defender to exempt Chromium from the regular scans.
This could also apply to any other anti virus software that is installed on your system.

Hope this helps,
Christian
