[LXWDL]

Hi, when i run the following command:
python ./tools/train_net.py --gpu=0 --solver=./models/pvanet_obsolete/example_train_384/solver.prototxt --weights=./models/pvanet/pva9.1/pva9.1_pretrained_no_fc6.caffemodel --iters=110000 --cfg=./models/pvanet_obsolete/cfgs/train.yml --imdb voc_2007_trainval
an error occurs as following:
Loading pretrained model weights from ./models/pvanet/pva9.1/pva9.1_pretrained_no_fc6.caffemodel

Anyone who knows how to solve this problem, I will be very grateful.
