Invalid version

[pirotex]

Hi all,

I am trying to build my nodes. I already did it a few months ago. But now the pipeline is quite the same but I got an exception

2023-02-15 10:42:53,393 : ERROR : ModalContext : : Node : Off-target : 4:18 : Configure failed (Py4JException): An exception was raised by the Python Proxy. Return Message: Traceback (most recent call last):

raise InvalidVersion(f"Invalid version: ‘{version}’")
packaging.version.InvalidVersion: Invalid version: ‘4.6.3.v202209271016’

What does it mean? Is it an invalid KNIME version, or is something wrong with the build system?

My KNIME is 4.6.1
I use the following line from the last version of the tutorial to build the extension:

build_python_extension.py --knime-version 4.6 src build

My conda environment file is:

name: offtarget_env_internal
channels:

• knime
• conda-forge
  dependencies:
• python=3.9 # base dependency
• knime-python-base>=4.7 # base dependency
• knime-extension>=4.7 # base dependency
• keras
• packaging
• h5py
• tensorflow-cpu
• py4j
• pandas
  Maybe it is because knime-extension is 4.7 in the env file?

Hi pirotex,

good question. You’re thought could be right with the 4.7 version. In your environment offtarget_env_internal, could you try downgrading via the following command?
conda install knime-python-base=4.6 knime-extension=4.6 -c knime -c conda-forge
Does that help?
If not, we will dig further

Best regards
Steffen

Hi Steffen,

Looks like it works, after I downgraded to 4.6. Thanks.

Additional question, can I somehow provide two pipelines in one repository for building for the 4.6 version and for the 4.7 version for apple M1/M2?

Hey, glad it worked.
To provide different information for the different pipelines for 4.6 and 4.7, respectively, I suggest maintaining different branches on GitHub. About how it could look like especially with tensorflow and the resulting different yamls for different OS, you can examine this example and its corresponding bundling ymls: Word2VecPyNodeTF/knime.yml at main · sim2000dg/Word2VecPyNodeTF · GitHub
Have a look at the current 4.7 guide in the following section for the setup in the knime.yml regarding apple silicon (arm-64) builds:
Create a New Python based KNIME Extension

Best regards
