Question about KNIME python numpy output

Hello,

I am very good at Python and Tensorflow, but I am newbie of KNIME.

I have a question.

Assuming that I am using “Python source” module in KNIME.

import tensorflow as tf

from tensorflow import keras

import numpy as np

import matplotlib.pyplot as plt

fashionmnist = keras.datasets.fashionmnist(trainimages, trainlabels), (testimages, testlabels) = fashionmnist.loaddata()

I want to use “train_images” numpy variable as output, and the dimension is (60000, 28, 28).

However, I found that numpy cannot be used for output of “Python source” module, but only “pandas dataframe” can be used. But, my data is 3d data, so conversion (from numpy to pandas) would be tricky…

Do you have any good solution for this?

Thank you!!!
