Cannot write to snapshot prefix

I am new to caffe and was trying out an online tutorial kind of thing. And when I use the solver, this is how it ends up.

Did you find a solution?

[Atena Nguyen]

Seems like the snapshot folder does not exist. Can you make sure that folder  '/home/insane/cats-dogs-tutorial/caffe_models/caffe_model_1/caffe_model_1' exist?
