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

@molinav I installes the hotfix branch

pip install git+https://github.com/matplotlib/[email protected]#subdirectory=packages/basemap

Hence I'm using the following package versions (pip list):

• basemap 1.3.9
• numpy 1.25.2
• matplotlib 3.7.3

I tested the new version with a few simple examples and it worked for me.

Thanks!

Thanks for pointing the bug! Just out of curiosity, which numpy version are you using?

[quickbrett]

I'm using the following versions:

• matplotlib 3.7.3
• numpy 1.25.2
• basemap 1.3.8

@quickbrett thanks for raising this issue and proposing the fix and @molinav thanks for maintaining this still great package. I actually got the same error, I think it is related to the latest numpy versions.

It seems that numpy.float was removed with its release 1.24.0 (https://numpy.org/devdocs/release/1.24.0-notes.html). I will replace it with the Python builtin float as suggested in the link.

Hopefully I can get some time soon to start a basic unit test collection, because these issues would be identified immediately with the automatic tests.

@quickbrett I just added the patch in a hotfix branch (1.3.9), your small example now works after the correction. I took this moment to correct all the references to numpy.float that I found in the whole library, mostly replaced with numpy.float64.

I am not sure when I will release 1.3.9, maybe I will do a couple of bugfixes more that are still around before tagging.

@quickbrett I have just added a couple of unit tests for Basemap.shadedrelief based on your snippet, so I am finally closing this issue. The bugfix will come with basemap 1.3.9 (hopefully soon).
