New Poppy Installation Broken?

[Kokomodo]

Hi,

I'm new to POPPY and have basic to intermediate python skills. I installed the poppy package with the dependencies as described in requirements.txt (as well as synphot_refactor) but get the following error when running the first (most simple) example:

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

Has numpy been updated since the last poppy release? The versions all match the requirements.txt file.

This is my code:

1 import poppy

2 import scipy

3 import numpy

4 import matplotlib

5 import synphot_refactor

6 poppy.version

7 numpy.version

8 print("Hello World.")

9 osys = poppy.OpticalSystem()

10 osys.add_pupil( poppy.CircularAperture(radius=3)) # pupil radius in meters

11 osys.add_detector(pixelscale=0.010, fov_arcsec=5.0) # image plane coordinates in arcseconds

12

13 psf = osys.calc_psf(2e-6) # wavelength in meters

14 poppy.display_psf(psf, title='The Airy Function')

Obviously lines 6 and 7 are incorrect. I'm not sure why the text edit lost the underscores, and yes they should be inside print calls. For some reason I cannot highlight the code in the issue post to format it properly.

this looks like https://github.com/spacetelescope/poppy/issues/544 which was fixed in https://github.com/spacetelescope/poppy/pull/545, until the next release you might try try cloning the develop branch and installing that (option 2, https://poppy-optics.readthedocs.io/en/latest/installation.html):

git clone https://github.com/spacetelescope/poppy.git
cd poppy
pip install -e .

Actually, I'm pretty sure I cloned the repository the first time I installed it rather than using pip. Given that I never made it past the first example, I may blow out the first install and try again. Maybe I hosed something up in the environment?

Okay...addendum. I blew out the old directory and started from scratch. I suspect that I screwed up something in the environment, or installed something outside the environment by mistake. This time I was careful to clone, create the environment, install from requirements.txt...and I did not install synphot yet. This all seemed to work. Man, that logging file is VERBOSE.

Or, maybe I did use the pip install the first time. Who knows?

Thanks for your help.
