I think you should chang the mask name corresponding to occluded objects and occluded objects on lines 326 and 328 in the /wwwroot/wangguangxu/BCNet-main/detectron2/data/datasets/coco.py file. |
Have you solved this problem? |
|
Have you try this code in COCO2017 dataset successfully? |
|
|
|
You can give the errors for debugging. |
按照教程中的步骤，我们发现读不到图片路劲，我们在config中将图片路径改成了绝对路径，在coco.py文件中将segm = anno.get("segmentation", None)# |
|
Let me see how your data files are placed, I feel like that's the problem here. |
After I download the coco2017 dataset, the path is set as follows: / wwwroot / zhangpan / bcnet main / datasets / coco /. Among them, there are annotations, train2017, val2017, test2017 under the coco folder. |
|
what's in your annotations folder？ |
|
|
you can try to leave the fllowing two jsonfiles only in annotations file.
instance_val2017.json
instance_train_2017_transform_slight_correct.json

@zhang-pan Have you executed it successfully? |
Thank you very much for your help, because our computer server is now being used by others and the GPU memory is insufficient. I will try it as soon as the server is idle and inform you of the results. |
Ok, have you downloaded KINS datasets?I can't find it. |

Oh thanks.I will try it .You can contact me for qq(934466043). |
OK |

I met the same problem...This is the problem whether it is my training coco dataset or the dataset I registered myself. The return log is as follows: (solution at the end) [04/24 16:08:31 d2.data.datasets.coco]: Loading datasets/coco/annotations/instances_train_2017_transform_slight_correct.json takes 24.22 seconds. Solve this problem by modifying the code(BCNet/detectron2/data/datasets/coco.py", line 332): |

Thank you for your reply, but I still have a few questions. If it is convenient, can you tell me your email, and I would like to consult further. |

You can double-check the path of the changed and the name of the image. |
I want to know whether the json file that the training reads in is instances_train2017.json or instances_train_2017_transform_slight_correct.json. |
When i use the dataset created by myself, my dataset contains only one type
