 You can change this using flags, like user (-u), current directory, and volumes (-w and -v).
 E.g. this behaves like the usual caffe executable:
 
-`docker run --rm -u $(id -u):$(id -g) -v $(pwd):$(pwd) -w $(pwd) bvlc/caffe caffe train --solver=example_solver.prototxt`

 Containers can also be used interactively, specifying e.g. `bash` or `ipython`
 instead of `caffe`.
