Passing max_detection_thresholds to MeanAveragePrecision breaks the calculation

[aamster]

🐛 Bug

Passing max_detection_thresholds other than 100 to MeanAveragePrecision causes .compute to return -1 for map

To Reproduce

Take the example at https://github.com/Lightning-AI/torchmetrics/blob/master/examples/detection_map.py but pass max_detection_thresholds=[50] to MeanAveragePrecision

Expected behavior

it should not return -1

Duplicate of #1153 it seems.

Hi @aamster,
Could you try running from master?

pip install https://github.com/Lightning-AI/torchmetrics/archive/master.zip

To me it seems the issue was fixed by this PR: #1712, because running the example as you are proposing seems to be producing the right answer.

@SkafteNicki it is fixed on master. I will close this issue then
