Error in fasterRCNN - Githubissues

maggiezha commented 5 years ago

After installing all the packages, when I ran train_model.py, I got this error: 2.0.0-dev20190519 loading annotations into memory... Traceback (most recent call last): File "trainmodel.py", line 28, in scale=(800, 1216)) File "/home/maggie/Desktop/TensorFlow-2.x-Tutorials/lesson26-fasterRCNN/detection/datasets/coco.py", line 33, in init self.coco = COCO("{}/annotations/instances{}2017.json".format(dataset_dir, subset)) File "/home/maggie/.local/lib/python3.6/site-packages/pycocotools/coco.py", line 84, in init dataset = json.load(open(annotation_file, 'r')) FileNotFoundError: [Errno 2] No such file or directory: '/scratch/llong/datasets/coco2017//annotations/instances_train2017.json'

Then I found this blog has some info, so I tried to download annotation from coco website and changed the directory to the annotation as the second person in this blog suggested: https://github.com/cocodataset/cocoapi/issues/191

but then I got another error: Traceback (most recent call last): File "train_model.py", line 8, in from detection.datasets import coco, data_generator File "/home/maggie/Desktop/TensorFlow-2.x-Tutorials/lesson26-fasterRCNN/detection/datasets/coco.py", line 38 self.cat_ids = self.coco.getCatIds() ^ IndentationError: unexpected indent

dragen1860 commented 5 years ago

it's just a indent error. I dnt know why but i suggest you solved it by yourself. i will test it later. thanks.

Thanks, the problem was solved when I modified the data dir in train_model.py (last time I modified coco.py and it did not work). The training started until epoch 0 200 1.8066142 and reported: tensorflow/core/framework/tensor.cc:755] Type not set Aborted (core dumped) Not sure if this means it was out of memory, but even I used export CUDA_VISIBLE_DEVICES=2 to specify to use my GV100 GPU which has 32GB memory, It did not work and nvidia-smi shows GV100 was not used, instead it always use TITAN V which only has 12GB memory

Hello, have you trained the FasterRCNN on COCO2017? If convenient, could you please share the final detection performance? Thanks.

batch_size设置太大，大于样本数了，所以出现以上错误。调低batch_size即可
