Hello All, I'm trying to run some test on CIFAR100 as well.
I started by changing the CIFAR10 scripts and tried to download the CIFAR100 dataset. This is the scripts content :
#!/usr/bin/env sh
# This scripts downloads the CIFAR100 (binary version) data and unzips it.
DIR="$( cd "$(dirname "$0")" ; pwd -P )"
cd $DIR
echo "Downloading..."
wget --no-check-certificate https://www.cs.toronto.edu/~kriz/cifar-100-binary.tar.gz
echo "Unzipping..."
tar -xf cifar-100-binary.tar.gz && rm -f cifar-100-binary.tar.gz
mv cifar-100-batches-bin/* . && rm -rf cifar-100-batches-bin
# Creation is split out because leveldb sometimes causes segfault
# and needs to be re-created.
echo "Done."
After executing it, this is what I get :
hossein@hossein:/media/hossein/tmpstore/caffe_new$ ./data/cifar100/get_cifar100.sh

Done.
As you see , the download is completed successfully, the files are extracted successfully as well,
but there is an error stating the move command failed! which I have no idea what its talking about!
mv: cannot stat ‘cifar-100-batches-bin/*’: No such file or directory
Here this is the contents of the cifar-100 contents after extraction

#!/usr/bin/env sh
# This script converts the cifar data into leveldb format.
EXAMPLE=examples/cifar100
DATA=data/cifar100
DBTYPE=lmdb
echo "Creating $DBTYPE..."
rm -rf $EXAMPLE/cifar100_train_$DBTYPE $EXAMPLE/cifar100_test_$DBTYPE
./build/examples/cifar100/convert_cifar_data.bin $DATA $EXAMPLE $DBTYPE
echo "Computing image mean..."
./build/tools/compute_image_mean -backend=$DBTYPE \
$EXAMPLE/cifar100_train_$DBTYPE $EXAMPLE/mean.binaryproto
echo "Done."
Which gives me this :
hossein@hossein:/media/hossein/tmpstore/caffe_new$ ./examples/cifar100/create_cifar100.sh
