I am using KNIME Analytics Platform v3.3.3.v201707231738.
I created a workflow using Palladian TextClassifierModelLearner and TextClassifierModelWriter to write a file named 'palladian-model.palladianDictionaryModel'.
And then in another workflow, I am trying to use Palladian TextClassifierModelReader node pointing the the saved model file above.
Palladian TextClassifierModelReader is erroring out with the following line in the log:
ERROR TextClassifierModelReader 0:313 Execute failed: Not in GZIP format
(answered via E-Mail)
For completeness, here's the solution:
[…] can you please try saving it with a filename of e.g. "palladian-model.palladianDictionaryModel.gz"? (use .gz file extension)
It might be, that GZIP compression is only applied when the file extension is explicitly given and the reader expects a compressed file.
