Fix deprecated numpy.float in cocoeval.py

[sadra-barikbin]

Fixes #505

[psyhtest]

This is really urgent now.

[cchan-lm]

Agreed. This is very urgent and we would not like to downgrade our version of numpy. Thanks!

[cchan-lm]

Did a hacky workaround without downgrading numpy, which happens to work for our needs until this repo gets updated. Needs to be done at the beginning of your script that imports pycocotools or at the topmost level of your package but YMMV:

from packaging import version
import numpy as np

if version.parse(np.__version__) >= version.parse("1.24.0"):
    np.float = np.float32

Could we get this merged @tylin, @pdollar?

[mikel-brostrom]

Sadly, nobody seems to maintain this repo anymore 😢

[jerpint]

can confirm with the latest versions of numpy, pycocotools breaks.

The fix proposed by @cchan-lm works but can definitely have unintended side effects

[wilderrodrigues]

So, is pycocotools dead? Should someone take over and make sure those merge requests get updated? We also need this Numpy changes.

[cchan-lm]

It might be... https://cocodataset.org/ mentions partnership with FiftyOne, so I wonder if this means pycocotools is no longer being maintained in favor of FiftyOne?

This script could be a good alternative to use from now on
