AttributeError: module 'numpy' has no attribute 'float'.

[LKPatel1]

I am following the beginners guide to run the codes but getting the following error, even after updating numpy version.

Traceback (most recent call last): File "/home/lpatel/src/demcoreg/demcoreg/dem_align.py", line 21, in from imview.lib import pltlib File "/home/lpatel/src/imview/imview/init.py", line 3, in from .lib import * File "/home/lpatel/src/imview/imview/lib/pltlib.py", line 19, in cpt_rainbow = gmtColormap.get_rainbow() ^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/lpatel/src/imview/imview/lib/gmtColormap.py", line 19, in get_rainbow d = gmtColormap(fn, reverse=rev) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/lpatel/src/imview/imview/lib/gmtColormap.py", line 74, in gmtColormap x = np.array( x , np.float) ^^^^^^^^ File "/home/lpatel/anaconda3/envs/ev1/lib/python3.11/site-packages/numpy/init.py", line 319, in getattr raise AttributeError(__former_attrs__[attr]) 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. Did you mean: 'cfloat'?

Thanks David for fixing this. :-)

Hello David I need a bit of help from you to coregister my DEMs (Svalbard region). I have entered as per the instructions provided but getting the error "Input images do not intersect". The all the image files are having similar projection (WGS84), even then its showing the same error.

Please check and let me know

I have attached the cropped DEMs also for your reference.

Thanks in advance for your help.

Thanks for the detailed report. Both DEMs must have a projection with units of meters for dem_align.py. You can use gdalwarp -r cubic -t_srs EPSG:XXXXX input_dem.tif output_dem_proj.tif where XXXXX is the UTM zone for Svalbard. Or some other local projection. Still need to add some checks for this: https://github.com/dshean/demcoreg/issues/28

Thanks David It is working well, It was the projection error. I reprojected the layers in a local projection with the units as meter, and I got the results. Thanks alot for your immediate response and help provided.
