i follow the GETTING_STARTED.md, but when run train.py : Augmentation scales: [1, 0.875, 0.75, 0.66] Could not open input stream Could not open input stream Could not open input stream Could not open input stream Could not open input stream Could not open input stream Could not open input stream

Hi @Zhuysheng , are you able to provide more details, or a minimal code that reproduces the error? Thanks!

[Zhuysheng]

@chaoyuaw first, i use reencode.sh to create the mpeg4_videos , then run
python train.py --lr 0.0003 --batch-size 40 --arch resnet152 \ --data-name ucf101 --representation iframe \ --data-root data/ucf101/mpeg4_videos \ --train-list data/datalists/ucf101_split1_train.txt \ --test-list data/datalists/ucf101_split1_test.txt \ --model-prefix ucf101_iframe_model \ --lr-steps 55 110 165 --epochs 220 \ --gpus 0 1

after print the net, it shows could not open input stream,

@Zhuysheng hey,i met same error,have you figure it out yet ?

[Zhuysheng]

@chaoyuaw @FelixZhang7 sorry, i havent solve it ,any idea?

[Tylerjoe]

maybe you should check the video used for train or test. you can print the video name in data_loader/coviar_data_loader.c to get which video can not be opened
