Getting error while to train mask_rcnn for custom coco dataset. #4267

fsultana44 commented 3 years ago

I am trying to train my custom coco data set for instance segmentation using mask rcnn but I got the error AssertionError: not found any coco record in dataset/COCO/annotations/train.json. For using my custom dataset, namely COCO, I modified the coco_instance.yml and provided the path of my custom datasets (image + annotation). Here is the snippet of the path modification paddle_error1 here are the error messages while I try to train the mask rcnn model. paddle_error22 to get rid of this error, I modified again my custom dataset path in the file coco_instance.yml from / to \ after that I got the another error ValueError: Dataset dataset\COCO is not valid and cannot parse dataset type 'dataset\COCO' for automaticly downloading, whichonly supports 'voc' , 'coco', 'wider_face', 'fruit', 'roadsign_voc' and 'mot' currently Here are the snippet of the error and modification. paddle_error3 paddle_error4 I found the same issue but for language barrier I could not solve my problem by getting ideas from the previous issue.

This problem raise for providing wrong class number in the file coco_instance.yml. My data set had 2 classes, I for got give number of classes 2+1 (1 for background).
