Couldn't open file: tmp/backup//mnist_lenet/weights

[zzyupupup]

When I execute the command darknetp classifier train -pp_start 4 -pp_end 10 cfg/mnist.dataset cfg/mnist_lenet.cfg to complete the training, the following error occurs

Saving weights to tmp/backup//mnist_lenet.weight
Couldn't open file: tmp/backup//mnist_lenet/weights

I made changes optee/out-br/target/root/cfg/mnist.dataset

backup = models/mnist

after completing training:

Saving weights to tmp/backup//mnist_lenet.weight

But there is no new weight file saved in the folder

execute the command darknetp classifier predict -pp_start 4 -pp_end 10 cfg/mnist.dataset cfg/mnist_lenet.cfg models/mnist/mnist_lenet.weights data/mnist/images/t_00007_c3.png

100.00%: 7
 0.00%: 1
 0.00%: 2
 0.00%: 0
 0.00%: 4

This is obviously wrong,How can I solve it?

Any help is appreciated!

@mofanv Can you help analyze the possible causes? Thanks.
