To me it looks like a python package is missing in the installed python modules but i don’t know if that is really the case. And if it is the case I don’t really know how to solve the problem since I just downloaded the packages via conda install as explained in the tutorial.
I still use KNIME AP 4.6 if that’s important for this issue.
I’m glad that you try it out!
4.6 is one important issue, indeed. Please use the guide for 4.6 instead of the latest 4.7 guide: Create a New Python based KNIME Extension
The difference is the creation of the conda package
Could you retry with such a package with the 4.6 version instead of your used knime_ext package?
Additionally, I am curious about the missing package. Could you please go to C:\Users\your_user\Anaconda3\envs\knime_ext\lib\site-packages and send me a screenshot of the version of the knime_extension package? It might look like the following:
conda activate knime_ext
conda list knime
and copy the outcome.
Furthermore, could you have a look whether in the site-packages folder, the tree structure looks like this? Especially with the folder having the files schema.py, table.py and views.py?
thank you for your fast answer. Sorry for my late reply.
I removed the 4.7 knime python packages from the conda envoirement and installed the 4.6 versions. This resolved the issue and I am now able to create my own Nodes with Python. So thank you very much.
I don’t know if you still need the other information but I couldn’t recreate the error, I’m sorry.
After installing the 4.6 version the folders look like this:
There is no folder called just knime.
If you’d like to receive additional information feel free to ask.
