release numpy.float fixes

[bmegli]

Hi @fsuarez6,

I am asking you as the author and official maintainer of the package.

Could the #7 fixes be released (bump package.xml version, bloom)?

With the removal of deprecated attributes in numpy, dependent ROS packages will now fail at runtime in noetic with updated numpy (e.g. pip version).

Some examples:

• baldor makes the package fails moveit/moveit_calibration#133
• https://github.com/crigroup/handeye
• ...

Kind regards

Edit:

• clarified when the problem happens

I've reverted #7 and will work on a proper fix so that we don't break previous ROS packages

For reference:

• deprecated
  • https://numpy.org/doc/stable/release/1.20.0-notes.html#using-the-aliases-of-builtin-types-like-np-int-is-deprecated
• expired
  • https://numpy.org/doc/stable/release/1.24.0-notes.html#expired-deprecations

Also, the problem may not happen on clean Focal + Noetic.

The apt numpy version is 17.4 (before deprecation and expiry).

apt-cache policy python3-numpy
python3-numpy:
  Installed: 1:1.17.4-5ubuntu3.1
  Candidate: 1:1.17.4-5ubuntu3.1

So the problem stems from something else updating numpy through pip and overriding system version.
(for general public)

@fsuarez6, I am fine to close this issue.

After investigation:

• clean Focal + Noetic should have older version of numpy that doesn't have this problem
• problem is caused by pip installed numpy >= 1. 24.0

You may still want to figure out forward and backward compatible solution but this is not urgent.
