AttributeError: module 'numpy' has no attribute 'float'.
`np.float` was a deprecated alias for the builtin `float`. To avoid this error in existing code, use `float` by itself. Doing this will not modify any behavior and is safe. If you specifically wanted the numpy scalar type, use `np.float64` here.
The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at:
    https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations

Hi Shiraz,

Thanks for your message and pointing this out. I think you are using an old version of the code as all the "np.float" references have now been removed since version 2.2.2.

You can get the latest version of Dans_Diffraction directly from GitHub: $ pip install git+https://github.com/DanPorter/Dans_Diffraction.git

This reminds me though that I haven't updated the PyPi package for some time so I should get round to this.

Please let me know if you have any further problems or any questions about the software.

[DanPorter]

I have now updated the version available through PyPi, please run the command: $ pip install --upgrade Dans_Diffraction
