Hi

How to deal with the following error:

ERROR Weka Predictor (3.7) 0:89       Unable to clone input data at port 1 (Weka model): Java heap space

Hi Malik,

if possible, you have the increase the size of the memory which KNIME may use on your local machine (=heap size). The model simply seems to be too big.

see https://tech.knime.org/faq#q4_2

Depending on the amount of memory (RAM) you have on your local machine you can set the value. For example if you have 4GigaByte of memory you can set the value to 2G or 3G.

Hope this helps,

Christian
