caffe.set_mode_gpu() crashes on windows workstation

[braulio barahona]

We have a caffe installation in a Windows workstation we access it via its python interface. It is possible to import caffe to a python interpreter

```

import caffe

```

However, it is not possible to instantiate a model since as far as I understand, the first thing to do is to set mode and gpu

```

caffe.set_mode_gpu();

caffe.set_device(gpu_id);

```

(see: https://caffe.berkeleyvision.org/tutorial/interfaces.html)

caffe immediately crashes after either of those commands:

Any hints as to how to solve it? Anyone with a similar problem? -- As far as I gather the installation of caffe went wrong. I did not do this myself (not that I know how to :/) but in anycase I do not have admin rights to the workstation. 

We are trying to run the Fast(er)-R-CNN models:

Thanks!

Looks like you're missing some python dependencies, perhaps? glog and boost are libraries used with caffe, but might have been located somewhere else when your installation was done. Any chance you've deleted or moved a file folder (a big ask to remember, I know), or updated your version of python/ uninstalled reinstalled a conda distribution recently? 

It might be easier to do a clean install rather than troubleshoot this if you don't know the person who installed it on your system. Tracking down dependencies in windows (especially without C experience) can be a huge pain. This repo helped me a ton doing my windows install.
