Issue with Python Script - Node

Hi Community,

I have been using the “Python Script” - Node in KNIME to score some of my models. For some weeks now though it is not working anymore and I get an error message (see below). I am not using “numpy” or “str” in an explicit way. The only packages Im using are pandas, pickle and datetime.

I would be very happy if somebody could help me out with this.

Thanks in advance!

ERROR Python Script 3:1 Execute failed: module ‘numpy’ has no attribute ‘str’.

np.str

was a deprecated alias for the builtin

str

. To avoid this error in existing code, use

str

by itself. Doing this will not modify any behavior and is safe. If you specifically wanted the numpy scalar type, use

np.str_

here.

The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at:
