'numpy.float64' error

[zeynepiskenderoglu]

I am trying to train instance segmentation model with mmdetection using dataset and I got this error
TypeError: 'numpy.float64' object cannot be interpreted as an integer

I want to segment with mmedetection (You can also find the mmdetection repo here. https://github.com/open-mmlab/mmdetection ) using the dataset in the link. https://github.com/pedropro/TACO

TACO dataset is a dataset in COCO format used for garbage detection. Classes in them ['Aluminium foil', 'Battery', 'Aluminium blister pack', 'Carded blister pack', 'Other plastic bottle', 'Clear plastic bottle', 'Glass bottle', 'Plastic bottle cap', 'Metal bottle cap', 'Broken glass', 'Food Can', 'Aerosol', 'Drink can', 'Toilet tube', 'Other carton', 'Egg carton', 'Drink carton', 'Corrugated carton', 'Meal carton', 'Pizza box', 'Paper cup', 'Disposable plastic cup', 'Foam cup', 'Glass cup', 'Other plastic cup', 'Food waste', 'Glass jar', 'Plastic lid', 'Metal lid', 'Other plastic', 'Magazine paper', 'Tissues', 'Wrapping paper', 'Normal paper', 'Paper bag', 'Plastified paper bag', 'Plastic film', 'Six pack rings', 'Garbage bag', 'Other plastic wrapper', 'Single-use carrier bag', 'Polypropylene bag', 'Crisp packet', 'Spread tub', 'Tupperware', 'Disposable food container', 'Foam food container', 'Other plastic container', 'Plastic glooves', 'Plastic utensils', 'Pop tab', 'Rope & strings', 'Scrap metal', 'Shoe', 'Squeezable tube', 'Plastic straw', 'Paper straw', 'Styrofoam piece', 'Unlabeled litter', 'Cigarette']

I obtained the data by following the instructions in the Getting started section in the TACO github repo. I separated the annotations.json file as test, train and valid with the help of https://pypi.org/project/echo1-coco-split/ link.

As you can see below, when I run it for the train after giving the path of the test, train and valid annotation files and images I have obtained to the config file in mmdetection for the train process, I get an error in the Evaluating section after the train part is finished.

TypeError: 'numpy.float64' object cannot be interpreted as an integer`

I converted the values in the segmentation part of the annotation files from float to integer, and I did the same for the values in the box part. but the problem was not fixed.
on this line where train for mmdetection is started train_detector(model, datasets, cfg, distributed=False, validate=True)
If validate=False, the train process is finished without an error, but since there is no validation, I cannot determine my accuracy (such as precision, recall). Also, although it was not the best result, it was not a correct train because it saved the last log. If I solve the float problem in the validation part here, I will continue my train process in a healthy way.
