training error

[kaishijeng]

I use the following script to do training:

python3 train_mvod_basenet.py --datasets /home/sma/2TB/VID2015/ILSVRC/Data/VID --batch_size 60 --num_epochs 30 --width_mult 1

But got errors below:

Any idea why this happens? Thanks,

Just have a look at train_mvod_basenet.py. You also need to provide the path to a cache-directory when you run train_mvod_basenet.py with --cache_path /tmp
