Good Morning All --

I got caffenet training working smoothly last year but i'm having trouble with the latest release of Caffe. Specifically, I cant seem to point "caffe train" to the train_val.prototxt location. With the solver.prototxt, there is a switch (--solver) to pass in the exact location of the file:

/home/myusername/caffe/build/tools/caffe train \
--solver=/home/myusername/caffe/models/bvlc_reference_caffenet/solver.prototxt

However, there is no such switch for the train_val.prototxt. It seems to be looking in some location, but it isnt clear what commands the location it is looking in...an environment variable? some default location? Because of that, the method always fails with File not found: models/bvlc_reference_caffenet/train_val.prototxt

The full error received is below. How does one point to a specific train_val.prototxt and/or where should one place the train_val.prototxt?

solver.prototxt has the path to the train_val.prototxt file.

This is the first line of my solver.prototxt file

net: "/path/to/train_val.prototxt"
