Cause

 

There have been some changes to NumPy version 1.24.0 onwards and np.bool has been deprecated. As such, it is not compatible with the Alteryx package in the Python tool.
 



Resolution

 


NumPy version 1.19.1 is pre-installed with Python tool. If you have upgraded the NumPy version to 1.24.0 and above but if you do not need to use this version, please downgrade the version to a lower version than 1.24.0. The minimum version should be version 1.19.1 to ensure compatibility.
