knime_io package

[najihyeon]

Hello,

I am trying to run a code but it keeps throwing me this error in pyspark Environment.

code :
import knime.scripting.io as knio

error:
No module named ‘knime’

I want to use this module to execute the code.

“df = knio.input_tables[0].to_pandas()”

or

Is there a way to install and use the package “knime_io”?

knime_io
thank you.

best,
NJH

@najihyeon I think you will have to install the new Python extension:

How to Set Up Your Python Extensions | KNIME

If you are interested in a more detailed discussion about KNIME and Python I have this blog entry:

KNIME and Python — Setting up and managing Conda environments

Also this:

Pickle data from KNIME python script node

@Agi the import has been changed to: import knime.scripting.io as knio While the syntax about the to_pandas() should be correct. Not sure if this will affect the pickle thing. Parquet might be another format you could use to transfer data. Where you can switch out the import in Spyder by the one you will use in knime.

Hello.

I have the same issue when using the knime_io package in the “PySpark Script” node.

I think “PySpark Script” node doesn’t have knime_io package.

So, I was wondering If there is a way that I can install this package on Spark environmemt.

Thanks,
hhkim

Hi,

right now, only the Python integration can use knime_io, knime_jupyter, and their more current parts knime.scripting.io and knime.scripting.jupyter.

@hhkim, this also applies to your question in an older thread.

Best regards
