Hi
I am using CV node for MLR. After I'd run my test I got the following error: ERROR KNIME-Worker-19 X-Aggregator Execute failed: Error while writing to buffer: Blob file location "/home/anna/knime_2.3.1/col_0/000/000" does not exist.
Any ideas what does it mean?
Thanks
Is there any way for us to reproduce the problem? Can you send us the workflow, including the data? What version of KNIME are you using?
Regards,
Bernd
Hi
Thank you for information. I wanted to bulid MLR for a toxicity data. I generated chemical descriptors using CDK and I wanted to build the model using CV to predict IC_50.
I found that some descriptors are seen as missing cells (don't know why yet - in excel all descriptors value are displayed) and this coused the errror. Using the missing value node resolved my problem.
Kind regards
Anna
