Error: "AttributeError: module 'numpy' has no attribute 'bool'" 


Running a Python script containing method to read in the incoming data set returns the following error if there is a boolean data type:

AttributeError: module 'numpy' has no attribute 'bool'

Environment Details

  • Alteryx Designer
    • Version(s): All
  • Numpy
    • Version > 1.23

Example of the full error as seen from the engine log file:




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.



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.
