Dear KNIME users,
I am using a Python Script (1 =>1) Node to make a prediction with a LSTM Keras neural network. After the algorithm finished the prediction I transform the nparray into an DataFrame so that I can copy it into the output_table.
For the transformation I am using pandas pd.DataFrame function.
After that I am printing the fist 5 rows with head()
function and the console shows following output:
Prediction
0 162.258362
1 169.368301
2 133.968216
3 136.190872
4 147.283401
Anyways this happens within the node. If I want to execute the node directly in the workflow the output_table does not match with the result of my prediction.
I am using output_table = pd_yhat.copy()
to copy my prediction table to the output_table.
So my question is: Why does this happen? Does anyone have an idea why the internal print of the prediction table is okay and after I copied it to the output_table and execute the node it outputs such huge numbers with no relation to the real values?
Thank you very much in advance.
